About CPT 94780

Documentation specificity, correct ICD-10 linkage, and modifier accuracy determine whether 94780 pays cleanly or triggers a denial. Verify CMS National Physician Fee Schedule status, applicable Medicare LCDs, and any payer-specific medical policies before submission.
94780 has 10 NCCI bundling edit pairs documented. Run your scrubber against the NCCI quarterly update before submission. When clinically warranted, use modifier 59 or the X-modifiers (XE, XS, XP, XU) to bypass an indicator-1 edit, with chart documentation supporting the distinct service.
Code Properties
RVU Breakdown
Every CPT code’s Medicare payment is calculated from three Relative Value Unit components: physician work, practice expense, and malpractice. Together they multiply by the conversion factor to produce the payment amount.
Payment = Total RVU × Conversion Factor ($33.4009) × Geographic Adjustment (GPCI). National averages shown. Actual payment varies by locality.
Medicare Payment by State
Medicare adjusts payment by locality based on GPCI (Geographic Practice Cost Index). Higher cost-of-living areas like California and New York pay more. Rural states pay less. Top 12 states shown.
Showing top 12 of 53 states. Full locality data available in CMS PFS Locality file.
NCCI Bundling Edits
10 pairsThese codes trigger National Correct Coding Initiative edits when billed with 94780. An indicator of 0 means the pair cannot be unbundled. Indicator 1 means modifier 59 or X-modifiers may allow separate billing with supporting documentation.
94780 + 0903T: bundled, modifier may bypass (indicator 1)
The most-asked bundling question on this code. Verdict pulled from the current NCCI quarterly file.
Modifier indicator 1 means a modifier may bypass the edit when the clinical scenario supports a distinct, separately identifiable service. Most billers default to modifier 59, but payers prefer the more specific X-modifiers (XE, XS, XP, XU) and pay them with less audit scrutiny. Documentation must establish the separation factor.
HCPCS/CPT procedure code definition
Billing 94780 alongside a bundled code without the correct modifier generates CARC 97 denials. Payers often flag these as audit risks. Document medical necessity for the separate service and apply modifier 59 or the appropriate X-modifier (XE, XS, XP, XU) only when clinically justified.
