MPPR (Multiple Procedure Payment Reduction)
A reimbursement policy applied by Medicare and most commercial insurers that reduces payment for secondary and subsequent procedures performed during the same patient encounter, on the grounds that certain overhead and practice expense costs are shared across procedures billed together.
The Multiple Procedure Payment Reduction rule reflects the logic that when a provider performs multiple procedures in a single visit, some costs — the facility, the clinical staff time for setup and documentation — are shared rather than duplicated. Under MPPR, the highest-valued procedure on the claim is typically reimbursed at 100 percent of the applicable rate, while secondary procedures are paid at a reduced percentage — commonly 50 percent for Medicare, though commercial contracts vary.
MPPR is particularly significant for specialties that routinely bill multiple procedure codes per visit. Physical therapy, occupational therapy, chiropractic, and certain surgical specialties are among the most heavily affected. For these practices, the effective per-visit reimbursement — after MPPR reductions — can differ materially from what the headline per-code rate would suggest.
Why MPPR matters for benchmarking
Comparing per-code rates across practices without accounting for MPPR treatment produces misleading benchmarks. Two practices may have identical rates for individual CPT codes but very different effective visit economics if their MPPR terms differ — different reduction percentages, different thresholds, or contractual exemptions for certain codes.
The correct unit of comparison for practices that bill multiple procedures per visit is the effective visit rate — what the practice actually collects per patient visit, across a representative case mix, after all MPPR reductions are applied. This is a more complex calculation than a simple code-level comparison, but it is the only comparison that accurately reflects the economics of the practice.
Negotiating MPPR terms
MPPR reduction percentages and exemptions are negotiable contract terms. Some practices have successfully negotiated more favorable MPPR treatment — higher reimbursement on secondary procedures — as part of broader contract renegotiations. Understanding what terms comparable practices have achieved is as important as understanding headline code rates in specialties where multi-procedure billing is common.
