We handle dermatology billing end to end, medical dermatology, surgical procedures, and pathology. Because derm claims hinge on precise lesion documentation, correct benign-vs-malignant coding, and modifiers, a specialty-trained team is what prevents the denials that plague the field.

## Dermatology billing we handle

- **Biopsies & lesion removal.** Correct codes by type, size, and count (benign vs malignant).
- **Excisions & repairs.** Benign and malignant excisions with the closure coded correctly, including intermediate and complex repair, adjacent tissue transfer, flaps, and grafts.
- **Mohs micrographic surgery.** Staged surgical coding with correct units.
- **Destruction procedures.** Cryotherapy and lesion destruction by count and type.
- **Phototherapy & PDT.** UVB and PUVA phototherapy and photodynamic therapy by session and site.
- **Intralesional injections.** Intralesional steroid injections, acne surgery, and wart treatment.
- **Biologics for psoriasis.** Injectable and infused biologics billed with the correct J-code, units, and prior authorization.
- **Pathology.** Dermatopathology billing where applicable.
- **Medical vs cosmetic.** Correct determination so non-covered services aren't misbilled.
- **Modifiers.** 25, 59, and anatomic modifiers applied correctly.

**The dermatology detail.** Excision codes depend on lesion size *and* margins, and multiple lesions need correct counts and modifiers. A same-day E/M with a procedure needs modifier 25. Missing any of these means denied or underpaid claims.

## Why dermatology practices lose revenue

The usual losses: wrong excision code for lesion size/margin, missing lesion counts, benign-vs-malignant coding errors, missing modifier 25 on same-day E/M plus procedure, and cosmetic services billed to insurance. Derm-trained coders prevent all of these.

## Dermatology billing FAQs

**Why is dermatology billing error-prone?

Excision and destruction codes depend on lesion size, type, margins, and count, and same-day E/M-plus-procedure needs modifier 25. Small documentation or modifier gaps cause frequent denials and underpayments.

**Do you code Mohs surgery?

Yes. Mohs is staged, and we code the stages and blocks correctly with the right units to capture full reimbursement.

**How do you handle cosmetic vs medical services?

We determine coverage up front so medically necessary procedures are billed to insurance and cosmetic services are handled as patient-pay, avoiding denials and compliance issues.

**How fast will we see results?

Most dermatology practices see cleaner claims within the first billing cycle and measurable denial reduction over 60 to 90 days.
