Billing tips

Verify medical necessity before service; most payers deny chemical peels as cosmetic unless documented for actinic keratosis, precancerous lesions, or medical dermatologic conditions
Impact: Prevents $374.57 write-off and potential patient balance billing disputes; obtain ABN when medical necessity is questionable
Bill in non-facility setting when possible to capture the $161.41 higher reimbursement ($374.57 vs $213.16)
Impact: Increases revenue by 75.7% per procedure when overhead and supply costs are comparable
Do not bill separately for supplies or topical anesthesia; these are included in the PE RVU of 9.26 for non-facility
Impact: Prevents denials and audits for unbundling; supply costs are already factored into the allowed amount
Document specific chemical agent concentration, application technique, and medical indication; avoid cosmetic terminology like 'rejuvenation' or 'anti-aging'
Impact: Increases approval rate from approximately 30% to 70% for borderline medical necessity cases
Check individual payer policies before billing; many commercial payers have explicit cosmetic exclusions while Medicare has local coverage determinations
Impact: Prevents claim submission that will result in automatic denial and appeals workload
For series of peels, verify whether payer requires prior authorization or has frequency limitations (commonly 1 per 90 days)
Impact: Prevents denial of subsequent treatments averaging $374.57 each

Always verify with the specific payer before performing the service.
