Policy changes eventually become operating decisions

Most coverage of Medicare payment changes stops at reimbursement. A practice reads that a rule changes payment for certain services, then asks the obvious question: How much revenue is at risk?

That question matters, but it is not the only operator question. Medicare practice expense and related Physician Fee Schedule changes also affect the billing-service decision. If the practice outsources billing, the policy change does not land only in the fee schedule. It changes the economics of the billing contract, the service’s incentive to work marginal claims, and the breakeven point between percentage-based outsourcing, flat-fee outsourcing, and internal staffing.

When Medicare payment assumptions shift, the practice should revisit how it pays for revenue cycle work. The answer is not automatically to switch vendors. The answer is to run the math before the next contract renewal.

How billing-service contracts absorb the change

Most independent practices that outsource billing use one of three structures. The first is a percentage of collections. A billing service may charge 4 to 9 percent of collected revenue, depending on specialty, claim complexity, volume, and scope. Under this model, service revenue moves with practice revenue. If collections fall on Medicare-heavy codes, the billing service’s fee falls too. Incentives remain roughly aligned, although the practice still needs to monitor performance.

The second structure is a flat fee per claim. The service may charge a fixed amount for each claim submitted or worked, regardless of payment amount. That can be clean and predictable, but it means the practice absorbs the full effect of a reimbursement change while the billing cost per claim stays stable.

The third structure is a monthly retainer. For some small practices, retainers can run roughly $5,000 to $15,000 per month depending on scope, staffing, and volume. Retainers may work when the service is broad and the practice has predictable needs. They can become harder to justify when reimbursement changes reduce claim margin.

The contract structure determines how a Medicare change flows through the practice. A percentage contract flexes with collections. A flat-fee or retainer contract may not.

The operator calculation should come first

Start with the top five Medicare procedure codes by volume. For each code, calculate expected post-change revenue per claim using the current fee schedule and locality. Then apply the billing service’s current rate. A 6 percent billing fee on a $120 allowed amount produces a different cost profile than 6 percent on a $90 allowed amount, even though the contract term has not changed.

Next, compare the percentage-based cost to flat-fee benchmarks. A flat-fee model might look attractive if the percentage fee is high and claim complexity is low. It may look less attractive when the claim requires documentation review, denial follow-up, modifier judgment, prior authorization support, or payer-specific appeal work.

Run the same calculation for commercial payer claims. Medicare policy changes may not directly change commercial contracts, but commercial payers create their own pressure through fee schedule updates, bundling edits, prior authorization rules, and denial patterns. A practice with a Medicare-heavy panel should not evaluate billing economics the same way as a practice with mostly commercial reimbursement.

Finally, decide whether the policy change warrants renegotiation, restructuring, or no action. For many practices, the answer will be renegotiate, not switch. But the decision should come from code-level economics, not a general impression that Medicare cuts are bad. Practices reviewing this decision can narrow billing or revenue cycle management (RCM) service candidates by specialty and reimbursement profile before starting another round of vendor calls.

What changes in the next vendor evaluation

For practices currently evaluating billing services, Medicare practice expense changes should alter the questions. Ask how the service handles Medicare-heavy versus commercial-heavy panels. Ask whether performance metrics are separated by payer category. Ask how the service reports denial rate, accounts receivable (AR) days, clean claim rate, and appeal success by payer type.

Contract flexibility also matters. If reimbursement structures shift mid-contract, can the fee model be reviewed? Does the agreement allow a move from percentage to flat fee, or from flat fee to percentage, if volume or payer mix changes? Does the service publish enough performance data to justify the fee when margins tighten?

Practices that have not reviewed billing-service performance in 18 months are more exposed. The service’s margin per claim may have shifted. The practice’s margin per claim may have shifted. The contract may still reflect an older reimbursement environment.

That does not make the billing service the problem. It means the contract should be tested against current economics. Medicare’s CY 2026 Physician Fee Schedule final rule includes conversion-factor increases, a finalized efficiency adjustment for many non-time-based services, and practice expense methodology updates. The code-level impact will not be identical across specialties or service mixes. A broad policy headline is not enough for an operator; the practice needs to know which codes drive revenue, which payer categories drive margin, and which billing contract terms change collection economics.

Run the math before changing the vendor

Policy changes are forcing a billing-service review many practices have not run. That review should not begin with a vendor switch. It should begin with the current contract, top Medicare codes, payer mix, billing fee model, and actual AR days and denial data.

If the numbers still support the current structure, keep it and monitor performance. If they do not, renegotiate before replacing the service. Switching vendors without the calculation only trades one unknown for another.
