Original Medicare generally reimburses CAH facility services based on allowable costs and RHC services through an all-inclusive rate methodology, subject to applicable payment limits. Medicare Advantage reimbursement is governed by applicable payment rules and negotiated contract terms.
Payment method
Look forPercent of charges, Medicare-based rates, fee schedules, carve-outs, and lesser-of provisions
Why it mattersDetermines actual reimbursement by service line
Medicare benchmark
Look forWhether Medicare refers to CAH cost-based rates, RHC AIR, OPPS, or the Physician Fee Schedule
Why it mattersDifferent benchmarks can produce substantially different payments
Escalators
Look forFixed or index-based annual increases
Why it mattersFlat rates lose value each year
Renewal
Look forAuto-renewal and termination notice windows
Why it mattersA missed window extends current rates
The formula is a simplified illustration. Actual revenue also depends on service mix, contractual adjustments, and patient responsibility.
Where contracts fall short
Six common contract gaps
01
Outdated ratesContracts renewed for years without comparing rates to current cost or Medicare-equivalent payment.
02
Undefined benchmark“Percent of Medicare” terms that do not define which Medicare methodology applies.
03
Amendments by referencePayer policy manuals that change coverage, coding, or payment rules without a new signature.
04
Denials and prior authorizationBroad authorization rules and short appeal windows that let revenue lapse.
05
No paid-to-expected monitoringContract terms not loaded in the billing system, so underpayments go unnoticed.
06
Untracked renewalsAuto-renewals and termination notice windows that are not calendared.
Review cycle
A contract review cycle
1Step
InventoryGather every contract, amendment, fee schedule, and policy manual, and calendar each renewal and notice date.
2Step
ModelCompare rates with cost and Medicare-equivalent payment by service line: inpatient, outpatient, emergency department, observation, swing bed, and RHC.
3Step
MonitorValidate remittances, adjustments, and patient responsibility against contract terms each month, and track denials by payer and reason.
4Step
NegotiateStart well before the notice window, with data on cost, access, and quality.
Warning signs
When a contract needs review
Rates have not changed through one or more renewals.
“Percent of Medicare” terms do not name a methodology.
Denials are rising and appeals are not tracked.
Paid amounts are never compared with expected amounts.
No one knows the next termination notice date.
A note on Medicare Advantage.Medicare Advantage plans generally must reimburse noncontracted providers at no less than applicable Original Medicare amounts. These payment requirements provide an important reference point when evaluating negotiated CAH and RHC rates.

Before the renewal date
Three checks before you sign
Know what it should payModel each contract by service line against cost and the applicable Medicare methodology.
Measure what it does payCompare remittances with expected amounts and track denials, so underpayments surface before renewal.
Bring evidence to the tableStart well before the notice window. Rates accepted without review are rarely revisited until the next renewal.

Why Payor Contract Reviews Matter
Protecting commercial and Medicare Advantage revenue for Critical Access Hospitals and Rural Health Clinics
Commercial and Medicare Advantage payments are set by negotiated contract terms, which may use Medicare-based methodologies.
The core questionDoes each contract pay at least what care costs to deliver, and do you collect what it promises?
Contract terms set the revenue
Realized revenue = Rate × Volume − Unrecovered denials − Underpayments
