Outpatient rehabilitation — physical therapy, occupational therapy, and speech-language pathology — is a fundamentally healthy sector facing a structural financial squeeze that is accelerating. Demand for services has never been stronger, yet practice margins are contracting sharply. Nine converging forces explain why: reimbursement rates falling in real terms for over two decades; a shrinking graduate pipeline burdened by debt; wages rising faster than reimbursement; a proliferating subscription technology stack; a prior authorization regime consuming 13+ staff hours per clinician per week; record medical office rents; Medicare Advantage penetration eroding effective rates for independent practices; PE-backed platforms absorbing margin compression better than independents; and credentialing delays creating invisible revenue gaps with every new hire. This whitepaper documents each pressure with current data and explains why the arithmetic for independent practice owners is increasingly unfavorable — and time-sensitive.
The Medicare Physician Fee Schedule conversion factor stood at $36.04 in 2019. By 2025 it had fallen to $32.35 — a nominal 10% drop over six years. Adjusted for the Medicare Economic Index (which tracks the actual cost of delivering services), the real erosion is far more severe. The professional associations have documented that reimbursement for key outpatient rehabilitation CPT codes is down approximately 40% in real terms since 2002. This is not a projected risk. It is a lived reality for practice owners today.
The 2026 Congressional "restoration" (+3.26%) returns rates only to approximately 2023 levels in nominal terms. It does not compensate for the 2025 cut, does not change the underlying budget neutrality structure, and is itself a temporary measure rather than a permanent fix.
Medicare's Physician Fee Schedule operates under a statutory budget neutrality requirement: increases for some providers must be offset by cuts elsewhere. Outpatient therapy is a perpetual offset target. In 2024, CMS implemented the G2211 primary care add-on code (~$16/qualifying visit), cutting the conversion factor by 3.37%. PT, OT, and SLP absorbed cuts of 3.4–4% that year. Behavioral health received a ~19.1% upward RVU adjustment — also funded partly by rehab offsets.
Compounding the issue: the PTA/OTA modifier, effective January 1, 2022 under the BBA of 2018, permanently sets reimbursement at 85% of the applicable rate for services delivered in whole or part by assistants. For practices relying on PTAs and COTAs to maintain clinical capacity — increasingly common given the DPT/OTD shortage — this is a structural 15% revenue haircut on a meaningful portion of visits.
The Bottom Line: When adjusted for inflation, providers are receiving roughly 40 cents of real purchasing power for every dollar Medicare paid for the same service in 2002. No commercial practice can absorb two decades of real rate decline without structural margin deterioration — especially when every other input cost is rising simultaneously.
A 2025 microsimulation study published in the Physical Therapy Journal — built on original APTA survey data — found that the U.S. had a deficit of 12,070 FTE physical therapists in 2022, the baseline year. That shortfall is projected to persist through 2037 even accounting for projected increases in graduation rates. APTA's 2024 survey found that 72% of PT respondents reported being at capacity or unable to meet local demand. One in three outpatient clinics reported an open PT position in 2023.
The OT picture is equally stark. OTCAS data shows applications to OT graduate programs fell by approximately 50% from the 2016–18 peak through 2024. ASHA projects 15% employment growth for SLPs through 2034 with 13,300 annual openings — demand that the current graduate pipeline is not prepared to meet.
The same reimbursement environment squeezing practice margins is also reducing the career's economic attractiveness to prospective students. OT median wages ($98,340 in 2024) lag those of comparably educated professions: nurse practitioners earn $133,260 and physician assistants earn $129,210 — both with entry-level master's degrees. The ~$30,000–$35,000 annual gap for the same educational investment is a powerful disincentive.
This creates an uncomfortable cycle: practices cannot raise wages sufficiently to attract clinicians (reimbursement won't support it), and they cannot expand capacity (no staff available). APTA's 2024 benchmark showed the overall vacancy rate re-accelerated from 10% in 2023 to 13% in 2024, driven by clinic growth outpacing available talent — with PTA vacancy jumping 17.2% in open positions year over year.
The Compound Effect: Labor scarcity doesn't just make hiring harder — it forces practices to use agency or travel PT staffing at $60–$90+ per hour, 2–3× the cost of a full-time clinician. It caps patient volume when practices can't hire to meet demand. And it reduces enterprise value at sale: an EBITDA profile built on under-staffed capacity is underwritten at a discount by institutional buyers who know the practice needs to hire before it can grow.

Between 2019 and 2024, median wages for PT, OT, SLP, PTA, and COTA all increased by 17–21% — approximately 3.5–4% per year on average per BLS occupational data. The PT median moved from $89,440 to $101,020 (+12.9%); SLP wages rose from ~$79,120 to $95,410 (+20.6%). In competitive urban and suburban markets, full-time experienced DPT clinicians now command $110,000–$120,000+ at market rate. These increases are not discretionary — they reflect a supply-demand reality where clinics that don't raise wages lose staff to competitors or PE-backed platforms.
A mid-career PT at $100,000 + 25% benefits = ~$125,000/year fully loaded, or ~$60/productive hour at 40 hrs/week. At 10–12 visits/day, labor cost per visit approaches $40–$50. Standard Medicare reimbursement for two common PT CPT codes — 97110 Therapeutic Exercise (2 units) and 97530 Therapeutic Activities (1 unit) — returns roughly $85–$100 at current national rates. Add billing overhead, software costs, rent, and administrative staff — and the margin per visit is razor-thin before the owner compensates themselves.
Clinics facing vacancies often resort to contract or travel PT at $60–$90+/hour — 2–3× the cost of staff clinicians — while simultaneously losing revenue from unfilled slots during 60–90 day average hiring cycles.
Why This Doesn't Resolve: Wage growth is driven by structural labor scarcity (Pressure #2) and cannot be reversed by individual practice decisions. The practices that have managed best are those that invested in retention — strong culture, clear career paths, flexible scheduling — rather than relying on compensation alone. These practices also command higher valuations at sale because their labor stability is a credible, diligence-verified asset.
Five years ago, a well-run outpatient PT practice needed a functional EMR, a billing solution, and a scheduling system. Combined software overhead might run $300–$600 per month for a small clinic. Today, the baseline infrastructure expected by institutional buyers, required for HIPAA compliance, and necessary for competitive operations has expanded dramatically. Cloud EMR platforms at $150–$300 per provider per month are table stakes. AI documentation tools — ambient scribing that generates SOAP notes from recorded encounters — have moved from optional to standard in clinics competing for tech-forward clinicians and managing documentation burden.
According to 2026 industry data, most healthcare providers pay $200–$700 per provider per month for cloud-based EMR software alone. Add AI scribing at $100–$200/provider/month, and software overhead for a 5-provider clinic can reach $30,000–$60,000 annually just for those two line items — a cost category that was negligible or non-existent in its current form a decade ago.
The subscription stack creates two compounding EBITDA problems. First, the absolute burden is real and large: a 5-provider outpatient clinic now carries an estimated $43,000–$99,000+ in annual software costs — essentially invisible compared to salaries and rent, but material at institutional valuation multiples. Second, because most costs are per-provider, scaling the practice scales the software overhead proportionally. Growing from 5 to 10 providers roughly doubles EMR licensing, AI documentation spend, and HR software cost — creating a headwind against the margin improvement owners typically expect from growth.
Why This Cannot Be Simply Cut: Institutional buyers building a platform expect and require a compliant, modern software stack. Attempting to downgrade infrastructure ahead of a sale introduces diligence risk and operational red flags. The correct strategy is not to reduce these costs — it is to ensure they are properly categorized and normalized where applicable in the financial recast before any buyer sees the financials. This is work Mihama performs as part of the standard engagement.
The American Medical Association's 2024 nationwide physician survey — 1,000 practicing physicians — documented the scale of the prior authorization burden with precision. Practices complete an average of 43 prior authorization requests per physician per week, consuming an equivalent of 13 hours of physician and staff time. More than 35% of physicians employ staff members working exclusively on prior authorization tasks — a dedicated administrative function that did not exist at this scale two decades ago.
For outpatient rehabilitation specifically, therapy services are subject to prior authorization at an extremely high rate, as APTA noted in its formal comments to CMS. This is particularly acute in Medicare Advantage plans, where PA requirements have expanded significantly even as traditional Medicare fee-for-service has not required PA for most PT/OT/SLP services. Given that MA enrollment now exceeds 50% of Medicare beneficiaries in many markets, this burden is not theoretical for most practices.
Prior authorization is not merely a clinical inconvenience — it is a direct financial drain. The 13 hours of staff time per clinician per week must be staffed and paid. For a front-desk or billing coordinator earning $45,000/year, that is approximately $21–$23/hour of labor cost consumed on non-revenue-generating activity. For a 5-provider clinic, the fully loaded annual cost of PA-related administrative labor can exceed $20,000–$40,000 depending on staffing model — before accounting for denied claims, delayed revenue, or physician time spent on peer-to-peer reviews.
Prior authorization also directly suppresses patient visit volume. Wait times of 1–2 weeks for PA approval on new episodes of care translate to deferred revenue, patient abandonment (82% of physicians report patients abandoning treatment due to PA delays), and incomplete care episodes that reduce outcome scores and referral rates. Revenue not collected from abandoned episodes is lost permanently.
Structural, Not Temporary: Despite pledges from major insurers (UnitedHealthcare, Cigna) to reduce PA volume, only 16% of physicians working with either insurer reported any actual reduction in the number of authorizations completed, per the 2024 AMA survey. CMS finalized rules requiring faster electronic PA responses beginning in 2026, but this addresses response time — not the underlying volume of authorization requirements that have proliferated across commercial, MA, and Medicaid payers. PA burden is a permanent, growing operating cost that must be modeled explicitly in any practice valuation.
Average triple-net asking rents for medical outpatient buildings (MOBs) reached a new national record of $24.92 per square foot in 2024, up 2.7% from 2023 — which was itself a prior record at $24.37/SF. This marks 15 consecutive quarters of declining MOB vacancy since the peak of 8.6% in Q1 2021. By year-end 2024, the national MOB vacancy rate had fallen to 7.0%. In top markets — New York, Boston, Houston, Los Angeles — rents significantly exceed the national average, with Manhattan medical space commanding $60+/SF.
The structural driver is simple: demand from outpatient healthcare providers is outpacing new supply. Net absorption of 18.0 million square feet in 2024 exceeded the 14.3 million square feet of new completions. High construction and borrowing costs are constraining new development, meaning the supply imbalance will persist. For practice owners renewing leases or seeking new space, there is no natural relief valve.
Outpatient rehabilitation practices typically occupy 1,500–4,000 square feet of medical-grade clinical space. At $24.92/SF NNN on a 3,000 SF clinic, base rent alone is approximately $74,760/year — before common area maintenance (CAM) fees, taxes, insurance, and utilities that can add 20–40% on a triple-net structure. In higher-cost markets, total occupancy costs on 3,000 SF can easily exceed $100,000–$150,000 annually.
Practices on leases signed 3–5 years ago at pre-record rents face significant step-ups at renewal. A lease signed at $20/SF in 2020 renewing at market in 2025 represents a 24.6% increase in base rent — typically non-negotiable in a low-vacancy market where landlords have pricing power and a queue of interested tenants. For a 3,000 SF clinic, that step-up alone is $14,760+ per year in additional occupancy expense, or ~$88,560 in reduced enterprise value at a 6x multiple.
The Timing Implication: Practice owners approaching a lease renewal face a choice: absorb the market-rate increase and accept the EBITDA reduction, or attempt to sell before renewal at current occupancy economics. In many cases, executing a sale prior to a significant lease step-up is a meaningful financial decision — the difference between being valued on current economics versus post-renewal economics can represent hundreds of thousands of dollars in proceeds. Mihama advisors routinely model this inflection point as part of transaction timing analysis.
Medicare Advantage enrollment has surpassed 50% of all Medicare beneficiaries nationally, with penetration exceeding 60–70% in major metro markets. This structural shift matters enormously for outpatient rehab practices because MA plans are not required to pay at traditional Medicare fee-for-service rates. Unlike Part B FFS, where the CMS Physician Fee Schedule sets a floor, MA plans negotiate rates individually with providers. For an independent 3–5 provider PT clinic, that negotiation is profoundly one-sided.
MA plans routinely pay at or below traditional Medicare rates, and in many markets pay 5–15% below the Part B fee schedule for PT/OT/SLP services. Some MA plans have implemented additional utilization management requirements — including prior authorization for therapy services that traditional Medicare does not require — effectively creating a dual burden of lower rates and higher administrative cost on the same beneficiary population.
This is where the competitive threat from PE-backed platforms becomes most concrete. A regional PT platform operating 30–50 clinics across a market has meaningful leverage in MA contract negotiations — payers need to offer competitive rates to maintain network adequacy. An independent practice with 1–3 locations has effectively zero leverage. It accepts the offered rate or leaves the network, which is rarely a viable choice when the plan covers a large percentage of the local senior population.
PE-backed consolidators use this leverage asymmetry explicitly: by acquiring independent practices and rolling them into a larger network, they can often renegotiate MA rates upward post-acquisition. That rate improvement is a direct EBITDA driver that independent owners cannot replicate on their own — but it does mean that independent practices are likely leaving money on the table relative to what their patient volume would command inside a larger network.
The Structural Disadvantage Compounds Over Time: As MA penetration continues to grow each year, the share of an independent practice's revenue subject to individually-negotiated MA rates — rather than federally-set Part B rates — increases. Independent practices face a slow, non-linear erosion of their effective reimbursement rate per Medicare-age patient even when the Part B conversion factor holds steady. This is an invisible pressure that doesn't appear as a line item on any fee schedule but shows up directly in revenue per visit over a multi-year horizon.
Private equity investment in outpatient rehabilitation accelerated dramatically from 2015 through 2023, creating regional and national platforms with dozens to hundreds of clinic locations. These platforms compete with independent practices for patients, clinicians, and referral relationships — but with structural economic advantages that compound each of the pressures documented in this whitepaper. The margin compression crisis is real for everyone in the sector, but PE-backed platforms are structurally better equipped to absorb it.
Scale advantages include: centralized billing with lower denial rates; preferred vendor pricing on EMR and software subscriptions (enterprise contracts vs. per-seat pricing); larger networks that support more competitive payer contract negotiation; HR departments that manage recruiting pipelines independent practices cannot afford; and shared administrative infrastructure that spreads fixed overhead across a much larger revenue base. When a platform acquires an independent clinic, many of the margin pressures documented here diminish or disappear almost immediately.
The window during which independent outpatient rehab practices command strong acquisition multiples from institutional buyers remains open — but the dynamics are time-bound. The same PE platforms that are acquiring independent practices today are also building their own de novo clinic networks and improving their operational infrastructure. As platforms mature, they become more selective and less reliant on acquiring independent practices for growth.
More critically: every year a practice operates under margin compression is a year of EBITDA that doesn't compound into sale proceeds. A practice with $400,000 of EBITDA today generating 5–10% annual EBITDA growth is worth more today than it will be worth in two years if margin compression erodes that growth to flat or negative. The arithmetic of waiting is not symmetric — the downside of margin deterioration falls entirely on the seller.
The Right Frame: Selling to a PE-backed platform is not capitulation — it is often the mechanism through which a practice owner monetizes the full value of what they built, participates in upside through rollover equity, and ensures their clinical team has the infrastructure and resources to thrive. The practices that sell well are those that engage a competitive process with multiple buyers — not a single off-market approach — and that present financials prepared by advisors who understand how institutional buyers underwrite healthcare services. That is exactly what Mihama is structured to do.
When a practice hires a new PT, OT, or SLP, that clinician cannot bill insurance independently under their own NPI until they have been credentialed and enrolled with each payer. Post-COVID, credentialing timelines with major commercial insurers and Medicare Advantage plans have extended significantly — 90–180 days is now common, with some payers taking longer. During this window, the practice faces a difficult set of choices: bill under a supervising clinician's NPI (which creates compliance risk in some states and payer contracts), defer the clinician's patient load until credentialing is complete (forgoing revenue), or carry the clinician's full salary while they are partially or fully non-billable.
The financial impact is direct and significant. A DPT hired at $95,000/year generating 10 visits/day at an average net collection of $90/visit produces approximately $225,000 in annual net revenue. A 120-day credentialing delay on even half that capacity represents $37,500 in deferred or lost revenue while full salary and benefits costs continue. For a practice that hires 2–3 new clinicians per year — common given the 13% vacancy rate — this becomes a recurring annual drag.
Credentialing is not a passive waiting exercise — it requires active management. Each payer has different application forms, documentation requirements, and follow-up protocols. Medicare enrollment alone involves PECOS applications, NPI registration, taxonomy code selection, and MAC-specific processing queues. Add four to six major commercial payers and two to three MA plans, and credentialing a single new clinician can require 20–40 hours of administrative staff time. Most practices either absorb this into existing front-office workload (reducing time available for scheduling, billing, and PA management) or pay for dedicated credentialing staff or outsourced credentialing services at $150–$400 per provider enrollment.
Practices that have not invested in credentialing automation or outsourcing often carry a backlog — resulting in clinicians who have been on staff for months but are still not enrolled with key payers, quietly limiting the practice's billable capacity without appearing on any single P&L line as an explicit cost.
Why This Is Relevant to Sale Timing: Practices with unresolved credentialing backlogs — clinicians not yet enrolled with key payers, lapsed re-credentialing creating network gaps — present diligence risk to institutional buyers. Buyers will identify these gaps, model the associated revenue risk, and either price it into the offer or request a working capital adjustment. Resolving credentialing gaps before going to market, and documenting clean enrollment status across all active clinicians and payers, is straightforward to address with adequate lead time and has a direct positive impact on how buyers underwrite the practice.
Each of the nine pressures documented here is structural and directional. Reimbursement rates are not returning to 2019 levels. Wage premiums will not decline while demand grows faster than the graduate pipeline. Software and occupancy costs will not fall. Prior authorization will not disappear. MA penetration will not reverse. Owners waiting for conditions to improve are waiting for a policy reversal that has not materialized in over two decades.
The nine pressures documented here also create opportunities for legitimate, defensible financial normalization. Owner compensation adjustments, non-recurring technology costs, one-time lease-related expenses, and PA-related items with identifiable recast value must be properly documented before any buyer sees the financials. Mihama identifies every available add-back before the marketing process begins.
Institutional buyers pay premium multiples for practices that have managed through these pressures and maintained healthy EBITDA. A well-run 5–10 provider clinic with documented systems, strong payer contracts, and a tenured management team is highly valued even in a compressed-margin environment. The underlying demand for outpatient services is genuine and growing.
Significant lease renewals at current market rents are a direct EBITDA event. Mihama models lease renewal inflection points as part of transaction timing analysis. Selling before a material step-up — while current occupancy economics are reflected in the financials — can produce meaningfully higher proceeds than selling after a renewal locks in higher fixed costs.
Mihama runs competitive auction processes against a national network of institutional buyers — PE platforms, strategics, and family offices — not single-buyer negotiations. The spread between an average offer and a premium offer in today's market routinely exceeds $1–2M for a mid-size practice. Capturing that spread requires a professionally prepared CIM, a defensible financial recast, and structured marketing that creates genuine buyer competition.
Many independent practices have never formally audited what their MA plan contracts pay relative to traditional Medicare benchmarks or what a larger network might negotiate. Mihama helps sellers understand and document their payer rate position — identifying where rate improvement is achievable post-acquisition and how to present that upside credibly to buyers.
Practices that enter a sale process with unresolved credentialing gaps — lapsed re-credentialing, unenrolled new hires, missing provider enrollment documentation — face buyer price adjustments or deal risk. A credentialing audit in the 6 months before going to market is a low-cost, high-return step that Mihama recommends to all sellers as part of standard transaction preparation.
Mihama engages practice owners 6–18 months before a target closing date to maximize preparation time: restructuring owner compensation, identifying recast items, reviewing payer contracts, and preparing the data room. Every month of preparation typically adds more to net proceeds than a month of waiting produces in incremental EBITDA at current margin trajectories.
The margin compression facing outpatient rehabilitation is real, documented, and accelerating across nine simultaneous structural forces. But it does not eliminate the value of well-run practices — it changes what is required to capture that value at the closing table. Mihama works with PT, OT, and SLP practice owners to recast financials, normalize operating costs, time transactions around inflection points, and run competitive processes that return maximum proceeds. If the arithmetic of your practice is tightening, the time to structure a sale is before the trend fully materializes in your EBITDA — not after.
