Dermatology medical billing has to correctly separate medically necessary procedures from cosmetic ones — cosmetic services aren’t billable to insurance at all, and miscategorizing them is a compliance risk, not just a lost-revenue one — while also handling highly specialized procedures like Mohs surgery that carry an unusually high documentation bar. TBC Solutions provides dedicated dermatology billing built around this exact distinction.
Why Dermatology Billing Is Different
- Medical dermatology (lesion removal, biopsies, treatment of skin conditions) is billable to insurance, while cosmetic dermatology is patient-pay only — miscategorizing a cosmetic procedure as medically necessary is a compliance risk that can trigger a payer audit.
- Mohs micrographic surgery (17311-17315) is one of the most specialized and highest-reimbursing procedures in dermatology, but it also carries a strict documentation requirement tying each additional stage to specific pathology findings.
- Lesion excision codes (11xxx range) are billed based on lesion size and location, and incorrect size documentation is a common, avoidable source of denial or underpayment.
- A same-visit E/M plus procedure (biopsy or excision) requires modifier -25 to get both reimbursed — a frequent denial trigger similar to urgent care and orthopedics.

Common Dermatology Billing Challenges We Solve
Medical versus cosmetic miscategorization
We apply clear, documented criteria to separate medically necessary from cosmetic procedures before billing, protecting the practice from compliance risk as well as denied claims.
Mohs surgery stage documentation
We ensure each additional Mohs stage billed is supported by the specific pathology findings required, since this is one of the most heavily scrutinized procedures in dermatology billing.
Lesion size and location documentation
We verify lesion size and location documentation supports the excision code billed, since size-based coding errors are a common cause of denial or underpayment.
Same-visit E/M plus procedure denials
We apply modifier -25 correctly whenever a same-visit E/M and procedure (biopsy or excision) are both billable, which is one of the most frequent denial triggers in dermatology.

Frequently Asked Questions
How do you handle the medical versus cosmetic billing distinction?
We apply clear, documented criteria before billing to ensure only medically necessary procedures are billed to insurance, protecting the practice from compliance risk as well as avoidable denials.
Do you have experience billing for Mohs surgery?
Yes — Mohs micrographic surgery requires documentation tying each additional stage to specific pathology findings, and our coders are trained on this exact requirement.
Why do lesion excision claims get denied or underpaid?
Usually due to lesion size or location documentation not clearly supporting the code billed. We verify this before submission rather than after a denial.
Can you bill for a biopsy performed during a regular office visit?
Yes — we apply modifier -25 correctly so both the E/M visit and the procedure are reimbursed, rather than one being bundled and denied.
Do you work with practices that offer both medical and cosmetic dermatology?
Yes — we handle the insurance billing for medical dermatology services while helping practices maintain a clean separation from patient-pay cosmetic services.
