How FHIRfly Prevents Denials

Most claim denials are preventable with the right data at the right time. FHIRfly provides four API endpoints that catch common denial reasons before claims leave your billing system — turning reactive rework into proactive validation.

NCCI PTP Validation

Query the CMS National Correct Coding Initiative procedure-to-procedure edits in real time. Before submitting a claim with multiple CPT codes, check whether code pairs are allowed together, require a modifier, or are mutually exclusive. This catches the most common coding denials — CO-4 (coding error) and CO-97 (already adjudicated) — before they reach the payer.

GET /v1/ncci/validate

Prevents CO-4Prevents CO-97

MUE Limits

Medically Unlikely Edits set the maximum units of service a provider would report for a single patient on a single day. FHIRfly returns the current MUE value and rationale for any CPT/HCPCS code, so your billing system can flag over-coded claims before submission. MUE violations (CO-151) are one of the easiest denials to prevent.

GET /v1/mue/:hcpcs

Prevents CO-151

PFS/RVU Data

Access the Medicare Physician Fee Schedule with work, practice expense, and malpractice RVU components. Use accurate payment rates to forecast expected reimbursement, identify undercoded services, and ensure claims include all required supporting data. Reduces CO-16 (missing information) denials by validating claims are complete before submission.

GET /v1/pfs/:hcpcs

Prevents CO-16

Coverage Check

Verify that an ICD-10 diagnosis code supports the billed CPT procedure according to Medicare Local and National Coverage Determinations (LCD/NCD). Coverage mismatches — where the diagnosis doesn't justify the procedure — are the single largest category of denials (CO-11). Pre-submission coverage validation eliminates these before they cost you.

GET /v1/coverage/check

Prevents CO-11

AI Agent Integration via MCP Server

Your AI coding assistant (Claude, GPT, etc.) can query all of these APIs in real-time via FHIRfly's MCP server — automatically evaluating every claim before submission. No manual lookups needed.
