The MPPR: Medicare's 50 Percent Therapy Payment Cut

When a therapy visit bills more than one procedure code, or more than one unit of the same code, Medicare doesn’t pay full price for every line. The Multiple Procedure Payment Reduction (MPPR) cuts the practice expense component of every unit after the first to 50 percent of its normal value, a rate in place since April 1, 2013. The reduction is automatic: the contractor ranks the day’s therapy units by practice expense RVU, pays the highest-ranked one in full, and halves practice expense on everything else.

This guide works from the primary sources: the Medicare Claims Processing Manual, §10.7, CMS Transmittal 1194, the American Taxpayer Relief Act of 2012, and the CY 2011 and CY 2026 PFS final rules, then walks the arithmetic using the CY 2026 RVU file. Current as of September 2026.

Why is my second CPT code paid less by Medicare?

Medicare has applied some version of this reduction since January 1, 2011. The CY 2011 Physician Fee Schedule final rule (75 FR 73026) created the therapy MPPR at 25 percent of practice expense. Congress then cut the rate to 20 percent for services paid under the fee schedule (offices and other non-institutional settings) for January 1, 2011 through March 31, 2013, while institutional settings stayed at the rule’s 25 percent, per Social Security Act §1848(b)(7) and CMS Transmittal 1194. Section 633 of the American Taxpayer Relief Act of 2012 then raised it to a flat 50 percent for every setting, effective April 1, 2013, by amending §1848(b)(7) for PFS-paid services and adding §1834(k)(7) for providers paid at PFS rates, which the CY 2011 rule describes as outpatient hospitals, home health agencies, CORFs, “and other entities that are paid by Medicare for outpatient therapy services.” The rate hasn’t moved since, so there’s no institutional-versus-professional advantage to chase anymore.

Mechanically, the manual is direct: “full payment is made for work and malpractice and 50 percent payment is made for the [practice expense].” Only the practice expense RVU is touched. The contractor applies this automatically to any code carrying Multiple Procedure indicator “5”; it isn’t triggered or blocked with a modifier, the way modifier 51 or a bilateral modifier works elsewhere. There is no MPPR modifier to append or omit.

Which therapy codes are subject to the MPPR?

The reduction applies to codes on CMS’s “always therapy” list, “excluding A/B MAC (B)-priced, bundled and add-on codes.” CMS marks each subject code with Multiple Procedure indicator 5 in the PFS National RVU file (RVU26A), defined there as “subject to 50% of the practice expense component for certain therapy services.” The CY 2026 MPPR rate file, linked from the CMS Therapy Services page, lists 51 codes subject to the reduction: PT/OT treatment codes (97110, 97112, 97116, 97140, 97530, and others), PT and OT evaluations (97161-97168), and speech-language codes such as 92507 and 92523.

Three categories are excluded even though they’re always-therapy services. Bundled codes never enter the ranking: hot and cold pack therapy (97010) carries both the “always therapy” and bundled dispositions on the 2026 Therapy Code List and Dispositions (annual therapy update page), so it’s never paid separately or ranked. Contractor-priced and add-on codes are excluded the same way, and “sometimes therapy” codes, such as remote therapeutic monitoring (98980, added 2022), aren’t on the MPPR list at all.

The worked examples below use these CY 2026 non-facility RVUs, national and unadjusted:

Source: PFS National RVU file, January 2026 release (RVU26A). GPCIs are held at 1.0 (national, unadjusted); your locality’s fee schedule will differ. See our CY 2027 fee schedule post for how the conversion factor itself is set.

How the MPPR math works, line by line

The payment formula is [(work RVU x work GPCI) + (PE RVU x PE GPCI) + (MP RVU x MP GPCI)] x conversion factor. Every figure below uses GPCIs of 1.0 and the CY 2026 nonqualifying-APM conversion factor of $33.4009, so these are national, unadjusted illustrations built from the RVU file, not CMS-published payment amounts; your MAC’s amounts will differ.

The ranking rule from §10.7: “contractors shall rank services according to the applicable PE relative value units (RVU) and price the service with the highest PE RVU at 100% and apply the appropriate MPPR to the remaining services.” Ties go to “highest total fee schedule amount.” In CY 2026, 97110 and 97116 share an identical PE RVU (0.41) and total RVU (0.87), so if both were the two highest-PE lines on a claim, that tie-break alone decides which pays in full; the practice has no way to influence it.

Here’s a full 60-minute PT visit billed as 97530 x1, 97110 x2, and 97140 x1 (4 units). Ranked by PE RVU, 97530 (0.60) is highest and is paid in full; the practice expense RVU on every other unit is halved before the total is computed:

Per unit, a reduced 97110 drops from $29.06 to $22.21, a cut of $6.85, or 23.6 percent of that unit; the visit-wide percentage is smaller only because one unit (97530) keeps full payment. Code order on the claim form doesn’t matter: the contractor re-ranks by PE RVU regardless of billed sequence.

Does the MPPR apply to multiple units of the same code?

Yes. The manual is explicit that “the MPPR applies to multiple units as well as multiple procedures.” A visit billed as 97110 x4 and nothing else still has only one full-payment slot: the first unit pays $29.06, and the remaining three pay the reduced rate of $22.21 each.

Billing one code four times instead of mixing codes doesn’t avoid the reduction; the 8-minute rule governs how many units the visit supports, and the MPPR applies to whichever units result.

How the MPPR stacks with CQ/CO and sequestration

The MPPR is one step in a fixed sequence. Per the manual: “the 15 percent reduction is taken last, e.g., after the MPPR (and other reductions where applicable) and right before sequestration.” Working from the 4-unit visit above, here’s the full order, allowed amount through sequestration, with and without the CQ/CO assistant modifier applied to every line:

Two things are easy to miss. Coinsurance is calculated on the MPPR-reduced amount, $20.14, not the unreduced $120.91: the manual states “the reduced amount is also used to calculate the beneficiary’s coinsurance and deductible amounts.” That’s the opposite of CQ/CO, where the 15 percent assistant reduction leaves coinsurance at the full allowed amount, as our CQ/CO post covers using CMS’s $100 example from Transmittal R11129CP. And on the remittance, MPPR-reduced lines carry Group Code CO with reason code 59 and MSN message 30.1, a different pair from the CARC 45 and RARC N851 combination the CQ/CO reduction uses. If a line is short for a reason you can’t trace to either, start with our claim denials guide.

How the MPPR affects the KX threshold

The KX modifier threshold accrues at the MPPR-reduced amount, not the unreduced one. The CY 2026 PFS final rule says so directly: CMS tracks “each beneficiary’s incurred expenses for therapy services annually and count[s] them towards the KX modifier and MR thresholds by applying the PFS rate for each service less any applicable multiple procedure payment reduction (MPPR) amount.” For the 4-unit visit above, $100.70 counts toward the threshold, not $120.91, so the beneficiary reaches it more slowly than the unreduced amount would suggest, the effect CMS anticipated in noting MPPR would let practitioners “furnish more medically necessary therapy services to a given beneficiary before surpassing the caps.” (The manual still calls this “therapy caps”; since 2018 it functions as the KX and medical review thresholds, not a hard cap.)

Does the MPPR apply across PT, OT, and speech on the same day?

Yes, and this is where the reduction surprises practices that treat disciplines as separate claims. The manual states the MPPR “applies to all therapy services furnished to a patient on the same day, regardless of whether the services are provided in one therapy discipline or multiple disciplines.” The CY 2011 final rule confirmed the same for separate sessions billed under one NPI: it applies “when multiple therapy services are billed on the same date of service for the same patient by the same practitioner or facility under the same NPI, regardless of whether those therapy services are furnished in separate sessions.” A group practice or facility counts as one NPI here; different NPIs, such as an independent PT practice and a separate OT practice, don’t get combined. CMS’s rationale for combining same-day, same-NPI services across disciplines was overlapping practice expense: “greeting the patient, obtaining vital signs, and post-visit phone calls.”

Evaluations are squarely inside this rule. Codes 97161 through 97168 carry Multiple Procedure indicator 5, and since eval codes typically carry the highest PE RVU in a visit, an eval almost always claims the full-payment slot, pushing every treatment unit that same day into the reduced tier. Take an eval-and-treat visit: 97161 x1 plus 97110 x2. The eval (PE RVU 1.38) outranks 97110 (PE RVU 0.41) and is paid in full; both 97110 units are reduced:

The $13.70 cut is entirely absorbed by the treatment units, because the eval occupies the top slot whenever it’s on the claim.

Can you avoid the MPPR?

Not by billing technique. The reduction isn’t a modifier a biller appends or withholds, the way modifier 51 or a bilateral modifier work elsewhere; it’s driven by Multiple Procedure indicator 5 on the code itself, applied automatically once more than one indicator-5 unit appears on the same date under the same NPI. Reordering claim lines doesn’t change the ranking, and splitting a visit into artificially separate sessions doesn’t help either, since same-NPI, same-day services are combined regardless of discipline or session.

The only real lever is the code mix: a visit weighted toward practice-expense-heavy codes concentrates the reduction on fewer dollars, while a work-heavy mix has less to reduce. That’s clinical decision-making, not billing strategy; codes billed have to match what was clinically necessary. The policy isn’t unique to Medicare, either: UnitedHealthcare’s Medicare Advantage policy states it is “applying a MPPR to the PE payment when more than one unit or procedure is provided to the same patient on the same day” for “procedures with a Multiple Procedure value of ‘5’ on the Medicare Fee Schedule Database,” per its MPPR for Therapy Services policy (policy version dated March 1, 2026), one confirmed example, not proof every commercial payer mirrors Medicare’s rule.

Getting the MPPR right starts with the unit math, before the reduction ever applies, and with tracking what actually accrues toward the KX threshold rather than the unreduced billed amount. PrismEHR sums timed units across codes as you document and lets organizations define their own billing rules, including minute and unit restrictions by code and payer, enforced at the point of documentation and reinforced again at claim creation, so the units feeding an MPPR-reduced claim and the KX threshold accrual behind it start from the right numbers.
