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.
