Understanding Medical Billing Fee Schedules: Medicare, Medicaid, and Commercial

What Is a Fee Schedule?

A fee schedule is a list of maximum allowable payments for medical services. Every payer — Medicare, Medicaid, and commercial insurers — maintains its own fee schedule that determines how much they'll reimburse for each CPT code.

Understanding fee schedules is essential for setting your practice's charge master, negotiating payer contracts, and projecting revenue.

Medicare Physician Fee Schedule (MPFS)

Medicare's fee schedule is based on the Resource-Based Relative Value Scale (RBRVS), which assigns each CPT code a relative value unit (RVU) consisting of three components:

• Work RVU: Reflects the time, skill, and intensity required to perform the service
• Practice Expense RVU: Covers overhead costs (rent, equipment, supplies, staff)
• Malpractice RVU: Accounts for professional liability insurance costs

The formula: Payment = [(Work RVU × Work GPCI) + (PE RVU × PE GPCI) + (MP RVU × MP GPCI)] × Conversion Factor

The 2025 conversion factor is approximately $32.74. Geographic Practice Cost Indices (GPCIs) adjust for local cost variations.

Medicaid Fee Schedules

Medicaid fee schedules are set by each state and are typically 30–40% lower than Medicare rates. Key characteristics:

• Rates vary significantly by state — some states pay as low as 50% of Medicare
• Some states use managed care organizations (MCOs) with their own fee schedules
• Annual updates may not keep pace with inflation
• Prior authorization requirements are often more stringent than Medicare or commercial payers

Commercial Payer Fee Schedules

Commercial payers negotiate fee schedules individually with each provider or group. Key points:

• Rates are typically expressed as a percentage of Medicare (e.g., 120% of Medicare, 150% of Medicare)
• Rates are negotiable — especially for high-volume providers or in-demand specialties
• Contract terms beyond rates matter too: timely filing limits, appeal rights, and termination clauses
• Fee schedule reviews should be conducted annually to ensure rates keep pace with Medicare updates

Setting Your Charge Master

Your charge master (fee schedule) should be set at or above the highest payer's allowable rate — typically 200–300% of Medicare. Here's why:

• If your charges are below a payer's allowed amount, you'll be paid your charge — leaving money on the table
• Setting charges uniformly high ensures you capture maximum reimbursement from every payer
• Review and update charges annually when Medicare rates change

Maximizing Reimbursement

1. Know your payer mix: Understand what percentage of revenue comes from each payer and prioritize contract negotiations accordingly
2. Benchmark your rates: Compare your contracted rates against Medicare and peer practices in your area
3. Negotiate proactively: Don't wait for contracts to auto-renew — request rate increases with data showing your value
4. Code accurately: Undercoding is as costly as overcoding — ensure services are coded at the appropriate level
5. Review EOBs: Verify that payers are paying according to contracted rates on every claim
