Aetna Dermatology Billing
Aetna publishes its coverage positions as clinical policy bulletins, which means most dermatology denials from Aetna were predictable before the claim was filed. The bulletin sets the clinical criteria, the precertification list sets what needs approval first, and the plan document decides whether the member's product carries the benefit at all. Denials arise where a note satisfies the clinician but not the bulletin.
The bulletin is the standard the reviewer applies
For dermatology, Aetna's bulletins cover lesion removal, laser treatment, phototherapy, biologics and cosmetic exclusions in specific clinical language. When an appeal quotes the bulletin's own criteria and points to the line in the note that meets them, it is far more likely to overturn than a general medical-necessity argument.
Bulletins are revised on Aetna's schedule. The version that governs a claim is the one in force on the date of service, and appealing against a newer version is a common own goal.
Precertification and how it fails
- Biologics and phototherapy generally require precertification with documented prior therapy and outcomes.
- An approval covers specific codes, units and a date range; anything performed outside that window is denied even though an approval exists.
- Site-of-service rules can move a payable procedure to a non-payable location for the same member.
Cosmetic definitions and modifier 25
Aetna applies cosmetic exclusions strictly, so the covered symptom — bleeding, pain, inflammation, functional impairment — must appear in the narrative rather than only in the diagnosis code.
Same-day evaluation billed with a procedure is a routine downcoding target. The note has to show a separately identifiable service, not a paragraph that restates the procedure.
Frequently asked questions
Where do we find Aetna's dermatology coverage criteria?
In the clinical policy bulletin for the service. Cite the bulletin in force on the date of service and quote its own criteria in the appeal.
Is Aetna's policy the same as Cigna's?
No. The two publish separate coverage policies and precertification lists. See our Cigna dermatology billing page for how that payer differs.
