Billing tips
Always bill 17107 with primary code 17106; 17107 cannot be reported alone and will auto-deny without the base code
Impact: Prevents 100% claim denial ($438.94 loss per claim)
Report 17107 only once per session regardless of total lesion count beyond 10; do not multiply units even if treating 50+ lesions
Impact: Prevents upcoding audits and recoupment; correct billing per CPT guidelines
Document exact lesion count, anatomical location, and size in operative note; specify medical necessity when treating over 15 lesions
Impact: Reduces audit risk and supports medical necessity; critical for payments exceeding $750 per session
Verify that lesions are vascular (not benign or premalignant) before using 17106/17107; use 17000-17004 or 17110-17111 for non-vascular lesions
Impact: Prevents downcoding from $438.94 to lower-paying codes ($100-200 difference)
For non-facility settings, ensure place of service is correctly coded as 11 to receive the higher rate of $438.94 vs $353.87
Impact: Captures additional $85.07 per procedure with correct POS coding
Check patient's Medicare LCD/NCD and commercial payer policies; many consider treatment of >15 lesions cosmetic unless specific diagnoses present
Impact: Prevents denials for cosmetic exclusions; pre-authorization can save $438.94 write-off
