PIP is mandatory coverage in no-fault states that pays the policyholder's medical expenses regardless of who caused the accident. Some states use "MedPay" for similar — though typically optional — coverage. The patient's own auto insurer pays bills directly as submitted, up to the policy limit. PIP limits range from a few thousand dollars to unlimited election options, depending on state and policy.

Filing deadlines are strict and state-specific — missing them forfeits your reimbursement entirely. PIP benefits can be exhausted mid-treatment if other providers have already billed against the policy. Always verify remaining PIP benefits at intake, re-verify after any gap in care, and confirm the applicable fee schedule or reimbursement methodology before rendering significant service.

Liability coverage on the at-fault party's auto policy compensates the injured person for damages including medical expenses, lost wages, and pain and suffering. The at-fault insurer does not pay individual bills as they are incurred. All medical damages are presented in a lump-sum demand at case resolution. The injured party — usually represented by a personal injury attorney — negotiates the settlement, and medical providers are paid from proceeds.

To preserve your right to payment, you must treat under a medical lien — a legal agreement that the patient and their attorney acknowledge your bill and agree it will be paid from settlement proceeds. Without a properly executed lien, your bill is unsecured and relies entirely on the patient's voluntary compliance after receiving their check. Cases can take 12–36 months; litigation can extend further.

If PIP is exhausted and the liability case is still pending, some practices bill the patient's group health insurance as a secondary payor to maintain cash flow. The health insurer will generally assert a subrogation lien against the personal injury settlement — meaning they expect reimbursement from settlement proceeds. This approach is situational, not a default strategy, and requires case-by-case COB analysis.

If the patient is on Medicare or Medicaid, the Medicare Secondary Payer Act requires that auto insurance pay primary. Do not bill Medicare as the primary payor for MVA-related services — doing so creates significant compliance exposure, including potential False Claims Act liability. ERISA-governed health plans have particularly aggressive subrogation rights and may reject MVA claims outright while a third-party claim is pending.

Execute the lien before or on the first visit. A lien signed after the case settles provides minimal protection. Lien law is highly state-specific — some states have statutory frameworks (California has one of the most developed); others rely entirely on contract law. A form enforceable in California may be unenforceable in Texas. Engage a healthcare attorney in your state to draft or review your lien form before using it commercially.

At settlement, personal injury attorneys routinely negotiate medical bill reductions to maximize the client's net recovery. You will almost certainly be asked to reduce your lien — this is standard, not bad faith. Your negotiating position depends on documentation quality, the lien's legal enforceability, and your relationship with the attorney. Most well-run practices find negotiated reductions of 25–35% produce the best combination of collection and referral preservation.

Your standard intake forms are insufficient. A dedicated MVA intake packet must capture: accident date and description, police report number and jurisdiction, all auto insurance information (patient's own PIP/MedPay and third-party liability policies), the claims adjuster's direct contact for each policy, the PI attorney's name and contact, and a signed medical lien agreement executed before or on the first visit.

Do not treat a liability MVA patient beyond the initial evaluation without a signed lien. If the patient is represented by a PI attorney, request written lien acknowledgment from the attorney's office before rendering more than one visit. Many experienced PI attorneys will proactively send a letter of protection or lien acknowledgment — if yours does not, request one before proceeding.

Every note must include: a clear mechanism-of-injury link (how the accident produced the presenting impairments), objective measurements — ROM, strength, pain scales, and validated outcome measures (NDI for cervical, PSFS for function, LEFS for lower extremity) — a narrative of functional limitations, progress toward stated goals, and an explicit medical necessity statement for continued treatment.

Documentation quality directly determines how much of your lien you will collect. MVA records are reviewed by defense attorneys, adjusters, independent medical examiners, and courts. Do not use templated, boilerplate clinical notes. Defense reviewers identify and systematically discount templated documentation — it gives them grounds to argue the treatment was cookie-cutter, not individualized and necessary.

For each MVA patient track: PIP/MedPay coverage limit and amount used, dates and amounts billed to PIP, PIP payments received (and any denials or IME cutoffs), lien balance (charges for dates not covered by PIP), attorney contact and periodic case status, settlement activity, lien negotiation correspondence, and final payment. Spreadsheet-based tracking is adequate for low-volume programs.

Standard practice management systems (WebPT, Therabill, Jane, etc.) are not designed for lien tracking — use a supplemental system. Practices carrying more than 10–15 active MVA cases simultaneously should consider dedicated PI billing software or a billing company that specializes in personal injury. The inability to produce case-level collection data is one of the most common due diligence problems in PT transactions involving practices with MVA revenue.

PIP claims have statutory filing deadlines in most no-fault states. Florida: 30 days for full reimbursement; 31–90 days for reduced reimbursement; after 90 days generally denied (Fla. Stat. §627.736(5)(c)). New York: 30 days from date of service (11 NYCRR §65-1.1). New Jersey: depends on insurer policy terms — verify. These deadlines are non-waivable; missing them forfeits your reimbursement entirely.

Submit PIP claims weekly. Do not batch and hold. Confirm receipt with the adjuster and document the confirmation. Follow up on unpaid claims at 30 days — PIP adjusters manage high volumes and delays are common. Build deadline milestone calendars for every active PIP case. For practices in no-fault states, PIP timely filing failure is the single most preventable source of MVA revenue loss.

Auto insurers — particularly in PIP-heavy states — regularly schedule independent medical examinations (IMEs) for injured patients. An IME is a one-time examination performed by a physician selected and compensated by the insurer, often with the objective of concluding that further treatment is not medically necessary. An IME finding can result in the insurer terminating PIP payment prospectively, even if the patient has remaining benefit dollars.

When an IME is scheduled: advise the patient of their right to request and review the IME report; ensure your most recent clinical notes are thorough and current; continue treatment as clinically indicated and document clearly why continued care remains necessary. If PIP is cut off following an IME, discuss with the PI attorney whether a peer review challenge or formal dispute process is appropriate. Many states have mandatory peer review mechanisms and insurer response timelines.

Liability cases take 12 to 36 months to resolve. If you build an MVA program without accounting for this in your cash flow model, you will watch your accounts receivable grow without corresponding cash conversion. For a practice just entering the MVA market, plan for at least 12 months before liability-case cash collections normalize. Maximize PIP billing speed to generate short-cycle cash from MVA cases in the interim.

Mitigate cash flow exposure by: limiting lien exposure per patient to a ceiling based on realistic case valuation (consider at-fault policy limits and competing liens); maintaining discipline about which cases you accept on lien; tracking MVA AR separately from commercial AR in your financial reporting; and establishing an internal cap on total outstanding lien receivable you will carry at any point in time. Many practices find an explicit ceiling prevents lien AR from ballooning during the ramp period.

PIP: $10,000 mandatory (Fla. Stat. §627.736). Covers 80% of emergency medical expenses; 60% for non-emergency. PT is a covered provider. Fee schedule: 80% of 200% of the applicable Medicare fee schedule — the 200% is the ceiling; insurer pays 80% of that amount. Insurers may alternatively apply 80% of reasonable charges. Initial treatment: must begin within 14 days of the accident or PIP is forfeited.

Filing: 30 days for full reimbursement; 31–90 days subject to reduced payment; after 90 days generally denied (§627.736(5)(c)). EUO and IME provisions frequently used by insurers. Active statewide PIP fraud enforcement — documentation must be meticulous. Lien law: No specific outpatient PT lien statute; liens enforced as contracts. Attorney fee arrangements in PI cases are regulated. SOL: 2 years for accidents occurring on or after March 24, 2023 (HB 837, §95.11(3)(a)); 4 years for accidents before that date. Always confirm which limitation period applies based on the accident date.

No-Fault: $50,000 minimum basic economic loss (Insurance Law §5102). PT covered. Fee schedule: NY Workers' Compensation Medical Fee Schedule — Physical Medicine & Rehabilitation section. Patient/attorney submits NF-2 (No-Fault Application); provider submits NF-3 (Attending Physician's Report) to bill. Serious injury threshold (§5102(d)) required to sue for non-economic damages: fracture, permanent loss of use, significant disfigurement, or 90/180-day limitation.

Filing: 30 days from date of service (11 NYCRR §65-1.1) — strict statutory deadline. Insurer must pay or deny within 30 days. Disputes go to mandatory Insurance Department arbitration. IME cutoffs common after 10–15 visits. Anti-fraud protocols are strict. Lien law: NY Lien Law §189 covers hospitals; outpatient PT relies on contract-based liens. 3-year SOL (CPLR §214).

PIP: $250,000 statutory default — if a driver does not affirmatively elect a lower limit, the policy defaults to $250,000 (N.J.S.A. 39:6A-4). Drivers may affirmatively elect lower limits (down to $15,000 minimum); catastrophic coverage at $250,000 is the default, not a high-end option. Drivers also elect limitation-on-lawsuit (verbal threshold) or no-limitation at purchase. PT is a covered provider. Fee schedule: NJ PIP Medical Fee Schedule (N.J.A.C. 11:3-29) — updated periodically; verify current rates with the NJ Department of Banking and Insurance. MCO arrangements may apply depending on insurer.

Filing: No single statutory deadline — varies by insurer policy terms; verify with each carrier. Pre-authorization often required beyond a visit threshold — failure to obtain pre-auth can result in denial. IMEs and peer review common. The verbal threshold election determines ability to sue for pain and suffering. Lien law: Contract-based liens recognized. Attorney ethics rules govern lien handling. 2-year SOL (N.J.S.A. 2A:14-2).

PIP (post-2019 reform, PA 21): Tiered menu — $50,000 (minimum; also the only tier available to Medicaid enrollees), $250,000, $500,000, or unlimited; Medicare Parts A & B recipients may opt out entirely of PIP medical coverage. Medicaid recipients may not opt out — they are limited to the $50,000 tier. Verify patient's coverage tier and insurance type at every intake — Medicare opt-outs have zero PIP coverage. PT covered under Michigan PIP Payment System (MPPS). Fee schedule: MPPS caps reimbursement as a percentage of Medicare rates — substantially lower than pre-reform levels. Rates were phased in under the reform; confirm current MPPS schedule.

Filing: 1 year from date of service (MCL 500.3145). IMEs heavily used. For liability cases, "serious impairment of body function" threshold required for non-economic damages (MCL 500.3135). Lien law: No specific outpatient PT lien statute; contract-based liens recognized. Post-reform, providers may sue PIP insurers directly for unpaid claims (provider standing restored). 3-year SOL for personal injury (MCL 600.5805).

PIP: $40,000 total mandatory ($20,000 medical; $20,000 income/replacement services) (Minn. Stat. §65B.44). PT covered. Fee schedule: Workers' Compensation rates used as the PIP benchmark — verify current PT rates with each insurer. Verbal threshold: Cannot sue for general damages unless medical expenses exceed $4,000, or injury results in death, permanent injury or disfigurement, or 60+ days of disability.

Filing: 6 months from date of service (Minn. Stat. §65B.54, subd. 1) — one of the shortest statutory PIP filing deadlines nationally. Missing it forfeits reimbursement entirely. Submit claims weekly; build deadline calendars at intake. Lien law: Medical Assistance lien applies in certain cases. Outpatient PT uses contract-based liens. ERISA health plan subrogation issues are common. 6-year SOL for auto accident claims (Minn. Stat. §541.05) — one of the longest in the country.

PIP: $8,000 mandatory (G.L. c. 90 §34A). Covers 75% of reasonable medical expenses (80% if insured has qualifying health insurance). PT covered. Fee schedule: Massachusetts Workers' Compensation Medical Fee Schedule applies. Coordination of Benefits: PIP pays the first $2,000 of medical bills automatically. Once that threshold is reached, the insurer issues a PIP Exhaust letter — providers must then bill the patient's private health insurance for subsequent charges before PIP covers any remaining balance up to the $8,000 limit. This is a coordination rule, not a patient deductible. Verbal threshold to sue: $2,000 in medical expenses or serious injury.

Filing: No single statutory deadline — policy terms govern; typically 30–90 days. Verify with each insurer. IMEs used frequently. Lien law: G.L. c. 111 §70A Hospital Lien Act covers hospitals; outpatient PT relies on contract-based liens. Health insurer subrogation rights are significantly limited under MA anti-subrogation rules — consult counsel before billing group health secondary. 3-year SOL (G.L. c. 260 §2A).

PIP: $10,000 mandatory (HRS §431:10C-103). Covers reasonable and necessary medical expenses. PT is a covered provider. Fee schedule: No specific statutory PT fee schedule — insurer applies reasonable charge methodology, often benchmarked to Hawaii Workers' Comp rates or UCR. Verify reimbursement methodology with each carrier before rendering significant service. Threshold to sue in tort: PIP benefits must be exhausted OR injury qualifies as serious injury (death, permanent serious disfigurement, or permanent loss of use of a body part) under HRS §431:10C-306.

Filing: No single statutory deadline — policy terms typically require submission within 30–90 days. Verify with each carrier. Lien law: Contract-based medical liens recognized. No statutory outpatient PT lien framework — engage Hawaii-licensed counsel for lien drafting. 2-year SOL for personal injury (HRS §657-7). Hawaii's relatively small market means attorney referral relationships are especially important for consistent MVA volume.

PIP: $4,500 minimum medical expense coverage (K.S.A. §40-3107) — one of the lowest mandatory PIP limits nationally. Additional income loss and other benefits also available. PT is a covered provider. Fee schedule: No statutory PT fee schedule for PIP — insurer applies reasonable charge. Verbal threshold: cannot sue for pain and suffering unless medical bills exceed $2,000 or injury causes death, permanent disfigurement, fracture, or permanent injury.

Filing: No single statutory deadline — policy terms govern; verify with each insurer. The $4,500 PIP minimum exhausts quickly for most PT patients — prepare lien documents at intake for every Kansas MVA case. Lien law: Contract-based liens recognized. No specific outpatient PT lien statute. 2-year SOL (K.S.A. §60-513). Given the low PIP limit, lien cases dominate; attorney relationship development is critical.

PIP: $10,000 mandatory by default (KRS §304.39-020). Drivers may affirmatively opt out of no-fault in writing, converting to full tort — verify coverage status at intake. PT is a covered provider. Fee schedule: No statutory PT fee schedule — insurer applies reasonable charge. Verbal threshold (if on PIP): cannot sue for pain and suffering unless medical expenses exceed $1,000 or serious injury.

Filing: No single statutory deadline — policy terms govern; verify with each carrier. Critical: 2-year statute of limitations for motor vehicle accidents (KRS §304.39-230, Kentucky MVRA). Unlike general personal injury claims in Kentucky (which carry a 1-year SOL under KRS §413.140), auto accident claims run two years from the date of injury or the date of the last PIP payment, whichever is later. Monitor long-pending cases; the last-PIP-payment trigger can extend the window but also requires careful tracking. Lien law: Kentucky Hospital Lien Act (KRS §376.240 et seq.) covers hospitals only; outpatient PT relies on contract-based liens.

PIP: $30,000 mandatory medical expense coverage (N.D.C.C. §26.1-41-01). PT is a covered provider. Fee schedule: No specific statutory PT fee schedule — insurer applies reasonable charge. The $30,000 PIP limit provides meaningful coverage for most PT treatment courses. Verbal threshold: cannot sue for non-economic damages unless medical expenses exceed $2,500 or injury results in permanent impairment, disfigurement, or 60+ days of disability.

Filing: No single statutory deadline — policy terms govern; verify with each insurer. IMEs used but less aggressively than FL or NY. Lien law: Contract-based medical liens recognized. No specific outpatient PT lien statute. 6-year SOL for personal injury (N.D.C.C. §28-01-16) — one of the longest in the country; longer runway for liability case resolution. Low population means attorney relationships are the primary referral driver.

PIP: $3,000 mandatory medical expense coverage (Utah Code §31A-22-307) — minimum exhausts quickly, often within a handful of PT visits. Additional optional PIP coverage available and frequently purchased. PT is a covered provider. Fee schedule: No specific statutory PT fee schedule — insurer applies reasonable charge. Verbal threshold: cannot sue for general damages unless medical expenses exceed $3,000 or injury involves death, permanent disability, disfigurement, or dismemberment.

Filing: No single statutory deadline — policy terms typically 30–90 days; verify with each carrier. Given the $3,000 PIP minimum, prepare lien documents and confirm attorney representation at intake for every Utah MVA patient. Lien law: Contract-based liens recognized. No specific outpatient PT lien statute. 4-year SOL (Utah Code §78B-2-307). Verify any optional PIP elected by the patient — higher optional tiers significantly change the revenue profile.

Pennsylvania is a choice no-fault state — drivers elect "limited tort" (restricted right to sue for pain and suffering) or "full tort" (unrestricted right) at policy purchase. Mandatory first-party benefit (PIP equivalent): $5,000 minimum. Most drivers elect full tort. PT is covered under the first-party benefit framework. No statutory PT fee schedule — insurer applies its own schedule or reasonable charges.

Filing: Policy terms govern (typically 30–180 days) — verify with each insurer. For full tort electors, liability cases proceed like fault states with no threshold for non-economic damages. For limited tort electors, the "serious injury" exception (death, serious impairment, or permanent serious disfigurement) must be met to pursue pain and suffering. Lien law: Contract-based; no specific outpatient PT lien statute. 2-year SOL (42 Pa. C.S. §5524).

Pure fault state — no mandatory PIP. Optional PIP must be offered by insurers; optional MedPay also available. MVA billing is predominantly liability/lien-driven. No statutory PT fee schedule for auto liability — bill chargemaster rates. Modified comparative fault (51% bar). 2-year SOL (Tex. Civ. Prac. & Rem. Code §16.003). Texas is one of the highest-volume MVA litigation states nationally — attorney referral relationships drive the majority of liability case volume.

Texas Health Care Provider Lien Act (Tex. Prop. Code Ch. 55) provides a statutory lien right for qualifying healthcare providers, including PT practices in many cases. Specific notice and filing requirements must be met for the lien to attach — lien must be filed with the county clerk and copies served on defendant and their insurer. Practices that do not meet statutory requirements must rely on contract-based liens. Tex. Gov't Code §82.065 governs attorney contingency fee arrangements in PI cases generally — document all lien reduction negotiations carefully. Engage TX-licensed healthcare counsel to confirm eligibility and filing requirements.

Pure fault state — no mandatory PIP. Optional MedPay available. MVA billing is predominantly liability-based, making the medical lien the primary payment instrument. No statutory PT fee schedule for auto liability — bill chargemaster rates. BI minimum limits increased to $30,000/$60,000 effective January 1, 2025 (SB 1107), up from the prior $15,000/$30,000. Many policies carry significantly higher limits. Pure comparative fault. 2-year SOL (CCP §335.1).

California Hospital Lien Act (Civil Code §3045.1 et seq.) covers hospitals and certain providers; outpatient PT relies primarily on contract-based liens supported by extensive case law — one of the most developed contract lien environments nationally. Third-party lien assignment to lien buyers is common in California; understand the regulatory landscape before assigning liens. Proposition 213 limits recovery for uninsured drivers. California has specific ethical rules governing attorney handling of medical liens. Engage CA-licensed healthcare counsel for lien form drafting.

Pure fault state — no mandatory PIP. Optional MedPay available. MVA billing is liability-driven. No statutory PT fee schedule for auto liability — bill chargemaster rates. Modified comparative fault (51% bar — if plaintiff is 51%+ at fault, no recovery). 2-year SOL (735 ILCS 5/13-202). Illinois is a high-volume MVA litigation state with a particularly active Chicago-area PI ecosystem.

Illinois Health Care Services Lien Act (770 ILCS 23/1 et seq.) is one of the strongest outpatient PT lien statutes in the country. It applies to licensed healthcare providers including PT. Liens must be perfected by serving written notice on both the defendant and their insurer — failure to properly serve forfeits lien rights. Lien amount is limited to one-third of the gross recovery. The act provides specific enforcement mechanisms. Total aggregate lien amount is capped at 40% of the settlement. Engage IL-licensed counsel to ensure proper perfection.

Georgia: Modified comparative fault (50% bar). Hospital Lien Act (O.C.G.A. §44-14-470) covers hospitals only — outpatient PT uses contract liens. 2-year SOL. High-volume MVA market, especially Atlanta. Virginia: Contributory negligence — any plaintiff fault may bar recovery. Medical Lien Act (Va. Code §8.01-66.2) covers emergency/hospital services; PT uses contract liens. 2-year SOL. North Carolina: Contributory negligence — any fault bars recovery; evaluate every case carefully before accepting on lien. Contract liens only. 3-year SOL. South Carolina: Modified comparative fault (51% bar). Hospital Lien Act (S.C. Code §44-63-10) — hospitals only; PT uses contract liens. 3-year SOL.

Tennessee: Modified comparative fault (50% bar). Tennessee Medical Lien Act (Tenn. Code Ann. §29-22-101 et seq.) covers licensed healthcare providers including PT — one of the stronger outpatient lien statutes in the Southeast. 1-year SOL for personal injury (Tenn. Code Ann. §28-3-104) — one of the shortest in the country; monitor pending cases closely. Alabama: Contributory negligence — any plaintiff fault may bar recovery. Hospital Lien Act (Ala. Code §35-11-370) covers hospitals only; PT uses contract liens. 2-year SOL. Contributory negligence states (VA, NC, AL) carry significantly elevated lien collection risk — apply strict case selection criteria.

Medicare / Medicaid: 14–30 days from clean claim submission. The fastest-pay payor class — highly predictable, electronically adjudicated. Commercial insurance: 30–45 days for in-network claims; 45–90 days for out-of-network. Predictable within a narrow band. PIP (no-fault states): 30–60 days — comparable to commercial if timely filing requirements are met. MVA liability / lien: 12–36 months from date of service to final collection. Litigation cases routinely exceed 36 months. This is the defining operational challenge of MVA billing and the primary reason many practices avoid it.

The cost of deferred collection is real and should be modeled explicitly before launching a program. A lien case billed at $8,000 that resolves in 24 months represents a meaningful opportunity cost relative to the same revenue collected in 45 days from a commercial payor. The financial case for MVA only holds when the effective rate premium — your actual net collection per visit after reductions — is meaningfully higher than your commercial rate. If your commercial rate and your net lien rate are close, the collection delay and operational overhead make MVA billing a poor tradeoff. If the premium is substantial, the math shifts materially in your favor.

Medicare: Sets the reference benchmark. Most PT services reimburse at Medicare rates. Commercial insurance: Contracted rates vary widely — many commercial contracts, particularly with dominant regional payors and Medicaid managed care plans, pay at or even below Medicare rates for PT services. Better-negotiated contracts with major commercial carriers may reach 110–130% of Medicare in favorable markets, but at-or-below-Medicare commercial rates are common across much of the country, especially for smaller or newer practices. MVA liability/lien: You bill at chargemaster — commonly 200–300% of Medicare or higher. After a 25–35% negotiated lien reduction, effective collection frequently lands well above what most commercial contracts pay, even accounting for the write-off.

The rate advantage is most pronounced on high-unit-value treatment days — visits with therapeutic exercise, manual therapy, neuromuscular re-education, and modalities all billed together. Commercial fee schedules often bundle or cap these combinations. Lien billing captures the full chargemaster value of each unit billed, subject only to negotiation at resolution. The premium is also strongest for practices with well-developed chargemasters — those billing at UCR or above, not practices that have let their fee schedules stagnate at near-Medicare levels. Before launching MVA billing, audit your chargemaster. If your gross charges are close to your contracted rates, the lien billing advantage largely disappears.

Your effective lien rate exceeds commercial by 40%+. At that premium, the collection delay is economically justified for a well-capitalized practice. PIP provides short-cycle cash. In no-fault states, PIP income normalizes cash flow while liability cases age. Volume is consistent. Sporadic MVA cases add overhead without proportional return. A program producing 15–20+ MVA cases per month reaches operational efficiency. Documentation already meets a high standard. The marginal cost of MVA-grade documentation is low for practices already operating at that level.

Your chargemaster is near Medicare or contracted rates. The lien premium depends on the distance between your gross charge and what you actually collect from commercial payors. If your chargemaster has stagnated near Medicare levels, fix that first — the premium is built on billing gross. You are in a pure fault state with no PIP penetration. Liability-only MVA programs require 18–24 months before collections normalize — a long runway with no short-cycle PIP income to sustain it. Your practice is within 2 years of a planned sale. Growing lien AR late in a practice's life creates valuation complexity. Buyers discount aged, unverified lien receivables heavily — or exclude them from the purchase price entirely. Your billing and documentation infrastructure needs major investment first. The cost of getting ready may exceed the near-term return.
