Payer mix and reimbursement strategy.

What to track.

• Revenue and collections by payer — in dollars and as a percent of total.
• Effective reimbursement per visit by payer.
• Denial and underpayment rates by payer.
• Contract anniversary dates — when can you renegotiate?
• Patient mix shift — is your patient population becoming more or less favorable?

The action plan.

Rank payers by effective reimbursement per visit. For underperformers: renegotiate, restructure (visit length, service offering), or strategically de-emphasize. For high performers: protect the relationship, watch the contract for changes, and grow the volume of the work they value most.

What payer mix actually controls.

Payer mix is the single biggest determinant of practice revenue at a given visit volume. Two practices with the same number of patients can have 30% different revenue based on contracts alone. Mix shapes:

• Revenue per visit across the schedule.
• A/R behavior — some payers pay in 14 days, others in 60.
• Denial rates — concentrated in 2–3 payers for most practices.
• Patient collection burden — high-deductible plans push more to patient responsibility.
• Administrative load — some payers require dramatically more documentation.

The mistakes that compound.

• Contracts that auto-renew at the original rate. Many practices haven’t renegotiated key payer contracts in 5–10 years.
• Acceptance without analysis. New contracts get signed because the patient population needs the access, without modeling the cost-to-collect.
• One payer over-concentration. When 40–50% of revenue comes from one payer, that payer effectively sets the practice’s margins.
• No fee schedule monitoring. Underpayments below the contracted rate are common and rarely caught.

Negotiation as a process.

Most practices treat payer negotiation as a once-every-few-years event triggered by a contract notice. The practices that move their rates treat negotiation as continuous: tracking benchmark data, documenting quality outcomes, knowing exactly which CPT codes drive volume, and approaching renewals with evidence rather than asking. The smaller the practice, the more this work pays off in dollars per provider.

Questions practice owners ask.

Should we drop our worst-paying payer? Only with a full model: patient volume, referral exposure, alternative payers in market, and the operational cost of carrying the contract. The honest answer is sometimes yes, sometimes no — but never “obvious.”

How do we benchmark our rates? Compare to Medicare allowable as a baseline (a payer at 105% of Medicare is meaningfully different from one at 80%). Specialty associations sometimes publish blinded ranges. Brokers can help on larger contracts.

Is going out-of-network ever a fit? For some specialties and some markets, yes. The math depends entirely on patient willingness to pay and the strength of the practice brand. It’s a strategy, not a default.
