TL;DR: If your rehab clinic is navigating MIPS, MVPs, PDPM, or bundled APMs, five metrics determine your financial and clinical performance: functional outcome scores, visit utilization, patient adherence, denial rates, and cost per episode. Tracking these manually is nearly impossible at scale — here's what each metric means and how to measure it.

Most physical therapy and rehab clinic owners know the concept of value-based care. Fewer know exactly which numbers they're being judged on — and fewer still track those numbers with the consistency that VBC programs demand.

That gap is expensive. Under MIPS, poor quality scores cost practices up to 9% of their Medicare Part B revenue. Under PDPM, inaccurate functional assessments directly distort payment. Under bundled APMs, a single episode with inflated costs eats into shared savings. In each case, the practices that win aren't just providing great care — they're measuring and documenting that care with precision.

This blog breaks down the five core value-based care metrics in healthcare that matter most for rehab clinics, explains how each connects to specific VBC programs (MIPS, MSK MVP, PDPM, and APMs), and shows you what to benchmark against — with authentic data.

Why Metrics Are the Foundation of Value-Based Care in Rehab

Value in healthcare is defined as measured patient outcomes relative to the cost of achieving those outcomes (Porter & Lee, Academic Medicine, 2021). That word — "measured" — is doing a lot of work. No measurement, no value. No value, no reimbursement advantage.

For rehab clinics specifically, the measurement imperative intensified with three converging forces: MIPS quality reporting (mandatory for most PT practices above the low-volume threshold), the 2024 launch of the MSK MVP (the first MIPS pathway benchmarking PTs against clinical peers), and PDPM's shift away from therapy minutes to patient-driven clinical characteristics in skilled nursing facilities.

The result: outcomes tracking in physical therapy is no longer a clinical best practice — it's a financial compliance requirement. A 2025 cross-sectional survey published in PLOS One found that while PTs recognize the value of standardized outcome measures, consistent implementation remains a challenge — particularly in resource-constrained settings. That gap between knowing and doing is exactly where reimbursement risk lives.

The 5 Key Value-Based Care Metrics Every Rehab Clinic Must Track

The table below defines each metric, how to calculate it, what to benchmark against, and which VBC program it directly affects:

Deep Dive: What Each Metric Reveals — and What to Do With It

1. Functional Outcome Scores: The Currency of VBC in PT

Functional outcome scores are the most direct evidence that your clinic is delivering measurable value. In the context of outcomes tracking in physical therapy, tools like FOTO, PROMIS, OPTIMAL, LEFS, and DASH translate clinical improvement into standardized, comparable data — data that MIPS quality reporting and APM contracts actually use.

Under the Rehabilitative Support for Musculoskeletal Care MVP (M1370), 7 of the 10 available quality measures use FOTO-based scores. Practices without systematic outcome data collection at intake, mid-episode, and discharge cannot meaningfully participate in this pathway — and will struggle to demonstrate quality performance in any VBC program.

A June 2025 clinical practice guideline published in Physical Therapy (Mayer et al.) established a core set of outcome measures for assessing physical function in acute care, reinforcing that standardized measurement is now a professional standard, not optional.

2. Visit Utilization: Efficiency Is Now a Measurable Asset

Visit utilization tells a more complex story than it appears. Under fee-for-service, more visits meant more revenue. Under VBC — particularly bundled APMs and the MIPS Cost Category — excessive visits without proportional outcome improvement signal inefficiency and inflate episode costs.

The MIPS Cost Category includes the Low Back Pain episode-based cost measure, calculated by CMS using claims data. Practices with high per-episode visit counts relative to outcome improvements will see this reflected negatively in their Cost score, which carries 30% weight in the total MIPS composite score starting 2025.

The benchmark: 70–85% visit utilization (actual vs. authorized) reflects appropriate care intensity. Below 60% often signals premature dropout; above 95% without documented outcome gains invites scrutiny.

 3. Patient Adherence: The Silent Killer of Outcome Scores

This is the metric most clinics underestimate. Industry data show that approximately 7 out of 10 patients do not complete all authorized visits, with no-show and cancellation rates ranging from 10% to 73% across outpatient settings (Thomas & Shaver et al., Musculoskeletal Science and Practice, 2025).

A 2024 study in JOSPT Open found that among patients with chronic pain, the self-discharge rate was 55%, with higher no-show rates significantly predicting premature dropout. For VBC purposes, this matters beyond the immediate revenue loss: patients who don't complete care plans produce incomplete outcome data, which either lowers quality scores or creates gaps in MIPS submission completeness.

Under bundled APMs, premature patient discharge often leads to unplanned readmissions or escalation of care — both APM penalty triggers. Practices that proactively monitor adherence can intervene early, protect outcomes, and defend their episode cost performance.

4. Denial Rates: The Revenue Metric With a Quality Shadow

Denial rates are typically treated as a billing problem. In a VBC environment, they're also a quality documentation problem. The two are inseparable: the same documentation gaps that cause claims to be denied are the gaps that undermine MIPS quality scores, PDPM MDS accuracy, and APM episode cost calculations.

The numbers are alarming: initial claim denials hit 11.8% in 2024 — up from 10.2% just a few years earlier. Medicare Advantage denials spiked 4.8% from 2023 to 2024. Denial amounts for outpatient coding rose 26% from 2024 to 2025 (MDaudit, 2025). The administrative cost per denied claim increased from $43.84 in 2022 to $57.23 in 2023 (Aptarro, 2025).

For PT practices specifically, CMS triggers Targeted Probe & Educate (TPE) audits when a patient's costs exceed $3,000 in a benefit period — placing high-denial practices at compounded risk of audit and clawback. The benchmark: best-practice PT clinics maintain denial rates below 5%.

5. Cost Per Episode: The Metric That Separates VBC Participants From Observers

Cost per episode is the defining financial metric of value-based care. It answers the question that MIPS, PDPM, and every bundled payment model is ultimately asking: How much does it cost your clinic to achieve a good outcome for a given condition?

A 2025 peer-reviewed study published in the Archives of Physical Medicine and Rehabilitation (via ScienceDirect) demonstrated that digital MSK programs generated per-person savings of over $2,000 in MSK care costs annually compared to in-person care, primarily through surgery avoidance and reduced imaging — illustrating how episode cost management can generate significant payer savings.

Under BPCI-A (Bundled Payments for Care Improvement Advanced) and similar bundled APM structures, practices earn shared savings when their episode costs fall below a target price — and face financial penalties when they exceed it. Knowing your baseline cost per episode by condition is a prerequisite for entering — or even evaluating — any bundled payment arrangement. 

Outcomes Tracking in Physical Therapy: Which Measurement Tools to Use

Selecting the right tool for the right condition is the first step in outcomes tracking that actually feeds your VBC reporting:

PDPM Explained: How Metrics Work in the SNF Setting

The Patient-Driven Payment Model (PDPM) — implemented October 1, 2019 — was CMS's first major shift away from volume-based therapy payments in skilled nursing facilities (SNFs). Under the prior RUG system, SNF therapy payments increased with therapy minutes. PDPM replaced therapy minutes with patient-driven clinical characteristics as the primary payment driver.

PDPM classifies each patient across five case-mix components: PT, OT, Speech-Language Pathology, Nursing, and Non-Therapy Ancillaries (NTA). Each component generates a per diem rate based on the patient's clinical complexity at admission — assessed through the Minimum Data Set (MDS). The PT component specifically weights functional status, primary diagnosis, and comorbidities.

What this means for metrics: Under PDPM, functional outcome documentation through the MDS directly determines payment accuracy. Inaccurate or incomplete functional assessments don't just undermine quality — they cause payment errors. The NTA component, often under-coded, can contribute hundreds of dollars per day when properly documented. Interim Payment Assessments (IPAs) allow recalibration when a patient's condition changes significantly, requiring ongoing functional tracking.

APTA emphasizes that PDPM redefines the relationship between payment and quality measures — making it "ever more important to show the value and cost-effectiveness of physical therapist services within skilled nursing facilities.

How These 5 Metrics Apply Across VBC Programs: PDPM, MIPS/MVP, and APMs

Tracking These Manually Is Nearly Impossible at Scale

Here's the operational reality: a clinic seeing 40 patients per week generates hundreds of data points weekly across outcome scores, visit utilization flags, adherence patterns, billing edits, and episode cost inputs. Correlating these into actionable MIPS quality submissions, PDPM MDS accuracy checks, or bundled payment episode reports manually — across multiple payers, conditions, and clinicians — is not a workflow problem. It's a structural impossibility at any meaningful scale.

The practices that perform best in VBC programs share a common infrastructure: a practice management platform that captures outcomes data as a byproduct of normal clinical documentation — not as a separate administrative task. When functional outcome scores are embedded into note templates, when denial patterns are flagged before claim submission, when adherence alerts trigger automatic patient outreach, the data you need to succeed in VBC programs generates itself.

Spry's AI-powered platform is built for exactly this: integrating outcomes measurement, MIPS quality tracking, denial prevention analytics, and episode cost visibility into a single clinical-administrative workflow — so your team captures VBC compliance data without slowing down care delivery.

Conclusion: Measure What Matters, Manage What You Measure

Value-based care rewards practices that can prove their value numerically. The five metrics covered here — functional outcome scores, visit utilization, patient adherence, denial rates, and cost per episode — are not abstract KPIs. They are the variables that determine your MIPS score, your PDPM payment accuracy, your shared savings eligibility under APMs, and ultimately your clinic's competitive position in an increasingly outcome-driven reimbursement landscape.

The gap between knowing these metrics exist and having systems that track them consistently is where most rehab clinics lose ground. Bridging that gap — through standardized outcome measurement tools, integrated practice management platforms, and proactive denial management — is the defining operational challenge of the VBC transition.

The good news: you don't need to solve it all at once. Start with functional outcome scores. Build the data habit. Then let the rest of the VBC infrastructure follow.
