Billing tips
Document exact square centimeter measurement with diagram or photographic evidence in operative report
Impact: Prevents 35-40% of documentation-based denials; measurement discrepancies are the #1 audit trigger for graft codes
Bill 15156 for each additional 100 sq cm beyond the first increment to capture full surface area treated
Impact: Failure to bill add-on code 15156 results in average underbilling of $500-$1,500 per case for extensive burns
Verify cultured autograft source with pathology/lab documentation confirming autologous origin before billing
Impact: Allograft or xenograft application uses different codes (15271-15278); incorrect code selection results in 100% denial and potential fraud investigation
Separate E/M services on same day require modifier 25 with clear documentation of distinct evaluation beyond graft procedure decision
Impact: Recovers $150-$300 in otherwise denied E/M services when complications require separate assessment
Use modifier 58 for staged procedures rather than 76/77 to indicate planned serial grafting in burn protocols
Impact: Ensures full reimbursement ($777.29) versus reduced payment (typically 50% or $388.65) for repeat procedures
Coordinate with facility coding to ensure supply charges for cultured graft products (often $5,000-$75,000) are billed separately
Impact: Professional fee of $777.29 does not include graft product cost; facility must bill C-codes or revenue codes to capture supply reimbursement
