The sliding fee scale is one of the defining operational requirements of FQHC status — and one of the most compliance-sensitive billing functions. Here is how it works:
HRSA requirements:
- FQHCs must maintain a Board-approved sliding fee discount policy
- The policy must cover all patients at or below 200% of the Federal Poverty Level (FPL)
- Patients below 100% FPL must be charged no more than a nominal fee (typically $20–$40 per visit, set by the FQHC Board)
- Patients between 100–200% FPL pay on a sliding scale between the nominal fee and the full fee
Billing implications:
- The sliding fee discount is applied to the patient’s portion after insurance — it is not a discount on the billed charge or the payer’s contractual rate
- Patient eligibility for the sliding fee must be documented at least annually — most FQHCs collect income verification at registration and update annually
- The discount must be applied consistently — HRSA compliance reviews specifically look for gaps in application (patients who qualify but were charged full price)
Revenue cycle considerations:
- The sliding fee scale reduces patient AR for eligible patients — billing teams must ensure patient statements correctly reflect the discounted amount, not the full patient responsibility from the EOB
- Write-offs for sliding fee discounts must be categorized correctly in the billing system — distinct from bad debt write-offs — for accurate cost reporting
- FQHCs must report their sliding fee discount program in their annual HRSA Uniform Data System (UDS) report
Common compliance gaps Squadyen finds in FQHC billing audits:
- Income verification not updated annually — patients receiving discounts they no longer qualify for, or paying full price when they should qualify
- Incorrect write-off categorization — sliding fee adjustments coded as bad debt, distorting cost report financials
- Inconsistent application across sites — multi-site FQHCs where some locations apply the policy differently than others
