Billing tips
Accurately measure and document the total surface area in square centimeters before applying the graft; use wound measurement tools and photograph documentation to support the claim
Impact: Prevents downcoding and denials; difference between 15110 (first 100 sq cm at $808.66) and underreporting can mean loss of appropriate reimbursement
Bill add-on code 15111 for each additional 100 sq cm beyond the first when total graft area exceeds 100 sq cm; this code cannot be billed alone
Impact: Each unit of 15111 adds significant revenue; failure to bill additional units can result in leaving substantial reimbursement unclaimed
Separately document and bill for recipient site preparation (CPT 15002-15005) when performed, as this is not included in the graft application code
Impact: Recipient site preparation codes reimburse separately and can add $200-500+ to the total claim when properly documented and medically necessary
Report the anatomic site accurately using body area descriptors; 15110 is specifically for trunk, arms, and legs—not face, neck, hands, feet, or genitalia which have separate codes
Impact: Incorrect site coding leads to automatic denials; using correct anatomic codes ensures proper payment and avoids audit flags
Link appropriate ICD-10 codes that support medical necessity, including burn degree, TBSA percentage, wound chronicity, and failed prior treatments
Impact: Strong diagnosis coding supporting medical necessity reduces denial rates by 30-40% and strengthens appeals for high-value procedures
For facility billing, ensure operating room time, supplies, and harvesting equipment are captured separately on the UB-04; physician professional services are billed separately on CMS-1500
