CMS raised the conversion factor for 2026. That is not the number that decides whether your clinic makes money. Three reductions applied after the fee schedule are.

Key Takeaways

  1. For CY 2026 CMS finalized two conversion factors for the first time: $33.57 for qualifying APM participants and $33.40 for everyone else, up from $32.35.
  2. Four separate eight-minute treatments totaling 32 minutes is two billable units, not four. Three units requires 38 to 52 timed minutes; four units requires at least 53.
  3. MPPR cuts the practice expense value of second and subsequent always-therapy codes by 50 percent on the same day, and practice expense is the largest RVU component in most therapy codes.
  4. Services furnished in whole or in part by a PTA are paid at 85 percent of the otherwise applicable Part B amount. Model PTA leverage at 85, not 100.

Two numbers define the CY 2026 payment year for outpatient physical therapy, and neither is the one most owners quote. CMS finalized a conversion factor of $33.40 for practitioners who are not qualifying alternative payment model participants, up from $32.35 – an increase of 3.26 percent. Qualifying APM participants receive $33.57, an increase of 3.77 percent. For the first time in the program’s history there are two conversion factors rather than one, and the large majority of private outpatient physical therapy practices sit on the lower of them.

A 3.26 percent increase is not a cut, and after several difficult years it is genuinely good news. But the conversion factor is a single input. What arrives in your account per visit is the product of the units you can legitimately bill, the relative value units attached to those codes, and three reductions that apply after the fee schedule has done its arithmetic: the multiple procedure payment reduction, the physical therapist assistant differential, and whatever patient responsibility your front desk does not collect. A practice that treats the conversion factor as the headline is watching the wrong dial.

The cost side keeps its own schedule. The Bureau of Labor Statistics put the median annual wage for physical therapists at $101,020 as of May 2024, with employment projected to grow 11 percent from 2024 to 2034 and roughly 13,200 openings a year over the decade. APTA’s 2024 benchmark survey of outpatient practices found a national vacancy rate of 9.5 percent, nearly double the 4.8 percent BLS reports across all industries, with about 13 percent of all PT and PTA positions at outpatient practices open. Labor is the dominant cost, labor is scarce, and the price of labor is not indexed to the conversion factor.

The Unit Is the Atom of This Business

Outpatient physical therapy economics reduce to two quantities: units billed per visit, and dollars collected per unit. Both are more tightly constrained than owners assume, and the constraints are written down.

CMS is explicit about how the 15-minute timed codes convert to units. When you furnish only one timed code in a day, you cannot bill it at all if it ran under 8 minutes. When you furnish more than one unit, the first unit and any intermediate units must each total at least 15 minutes, and the last unit counts as a full unit only if you provided at least 8 additional minutes. The arithmetic catches people. Four distinct eight-minute treatments totaling 32 minutes is two units, not four. A third unit requires 38 to 52 total timed minutes. A fourth requires at least 53. Time spent on untimed services – evaluations, group therapy, supervised modalities – does not count toward the timed-code total.

Read that as an operations constraint rather than a billing rule and it tells you exactly what your schedule template has to look like. If your target is four units per visit, your treatment blocks must reliably produce 53 or more minutes of one-on-one timed intervention per patient, documented to the minute. If your therapists are running two patients on overlapping blocks that leave roughly 40 real minutes each, you are structurally a three-unit clinic, and no coding seminar will change that. The schedule template is the billing policy. Everything else is commentary.

What MPPR Does to a Multi-Unit Visit

The multiple procedure payment reduction is the quietest few percent in the practice. APTA describes the policy plainly: a 50 percent reduction to the practice expense value of certain CPT codes designated always therapy services, applied to the second and each subsequent code furnished the same day. The service with the highest practice expense RVU is paid in full and the remainder are paid at half their practice expense component. Work and malpractice RVUs are untouched.

Practice expense is the largest RVU component in most therapy codes, which is precisely why halving it on codes two, three, and four is material. It also means the ranking that governs the reduction is by practice expense RVU, not by your fee schedule or your clinical priority. Very few practices model this. They build a fee schedule, look up the Medicare allowable per code, multiply by expected units, and arrive at a revenue projection that is optimistic before a single claim is denied. Model it once against your actual code mix and you will have a planning number you can defend.

Your schedule template is your billing policy. If the block does not produce the minutes, the units do not exist, and no coding seminar will conjure them.

The PTA Question Is a Margin Question

Since January 1, 2022, claims carrying the CQ modifier – outpatient physical therapy services furnished in whole or in part by a physical therapist assistant – are paid at 85 percent of the otherwise applicable Part B amount. CMS applies a de minimis standard: the modifier is required when the minutes furnished by the PTA independent of the physical therapist exceed 10 percent of the total minutes for that service. CMS also defines two narrow exceptions involving the final units of a treatment day, both spelled out in its documentation fact sheet, and neither one is intuitive enough to leave to memory.

The practical effect is that PTA leverage is a genuine margin lever with a known haircut attached. A PTA at a materially lower wage, delivering care paid at 85 percent of the PT rate, can be strongly accretive – or a net loss – depending on the wage differential, the payer mix, and what share of your visits are Medicare. The first mistake is running the staffing model at 100 percent and discovering the 15 percent in the remittance. The second is applying the modifier inconsistently, which converts a payment question into a compliance question you did not want.

Four Numbers, Reviewed Every Month

  • Units per visit, by therapist and by payer class. Not clinic average. The distribution is where the information is, and a two-unit therapist and a four-unit therapist inside the same average is a coaching problem, a template problem, or a documentation problem – and you cannot tell which from the average.
  • Collected dollars per unit. Collections, not charges, divided by units billed. This single figure absorbs your payer mix, MPPR, the PTA differential, denials, and uncollected patient balances. When it drifts, something structural moved.
  • Visits per therapist per clinical day, and the arrival rate behind it. Scheduled visits are a forecast. Kept visits are revenue. A clinic running 18 scheduled and 14 kept has a front-desk and reminder problem, not a capacity problem.
  • Patient responsibility collected at time of service. Deductibles and coinsurance collected at the desk versus billed later. The gap between those two is the most reliably recoverable money in an outpatient clinic.

From the Field

A three-clinic physical therapy practice in the Upper Midwest was averaging just under 2.8 units per visit and could not explain why one location ran a full unit higher than the others. The owner assumed it was a coding-knowledge gap and had already bought two rounds of continuing education. The operational review found the actual cause in the schedule template: the two lagging clinics ran overlapping 30-minute blocks with a shared gym transition, which left roughly 40 minutes of documented one-on-one timed intervention per patient – structurally a two-to-three unit day regardless of what the therapist knew. Rather than deliver a findings memo, our fractional COO engagement rebuilt the template around 45-minute anchored blocks with staggered starts, sat with each front desk through four weeks of rescheduling, retrained the therapists on documenting total timed minutes and total treatment time separately, and worked the first six weeks of remittances alongside the biller to confirm the units were surviving adjudication. Units per visit at the two lagging sites moved to 3.6 within one quarter on the same headcount and the same patient volume.

Advice, Execution, and the Difference Between Them

None of this is privileged information. A competent consultant will identify the unit constraint, the MPPR exposure, and the PTA modeling error inside a two-day engagement and hand you a clear, correct plan. If your practice has a clinic director or operations manager with real unclaimed hours, consulting is frequently the better value and the more economical choice, and we will tell you so on the call rather than sell you something larger.

The difficulty in most outpatient PT practices is not the plan. It is that rebuilding a schedule template is six weeks of rescheduling conversations with patients who liked their old time, retraining therapists on minute documentation while they are treating full caseloads, and reading remittances line by line to confirm the change actually held. That work happens inside your practice, on your calendar, with your staff. A fractional executive does the same analysis and then does that too – sitting with the front desk, reworking the template, running the first months of variance review until the habit sticks.

Be a deliberate buyer here. “Fractional executive” is an unregulated label, and some firms sell ordinary consulting under it. The test is simple: ask whether the person will be working inside your scheduling and documentation systems alongside your staff, or delivering a plan and leaving deployment to you. Both are legitimate services and both have their place. Only one of them is fractional executive work, and you should know which one you are buying before you sign anything.
