Med Bridge LLC handles dermatology medical billing for dermatologists, Mohs surgeons, and skin care clinics, with accurate CPT/ICD-10 coding, medical necessity documentation, and denial recovery. Get a free billing analysis.
Dermatology billing runs on volume, and volume hides mistakes. A quick lesion destruction here, a biopsy there, an E/M visit tacked on at the end — and half of it gets coded wrong because nobody documented the size, the site, or the reason it was medically necessary. Then the cosmetic versus medical line gets blurred, and payers start denying claims. Med Bridge LLC takes the whole dermatology revenue cycle off your plate, from eligibility checks through denial appeals, so your practice gets paid for the medical work it does.

Dermatology medical billing services cover the full revenue cycle for skin care practices: eligibility verification, charge capture, CPT/ICD-10/HCPCS coding, claim submission, payment posting, and denial management.
Destruction, excision, and biopsy codes depend on lesion size, site, and whether margins were taken. A 0.5 cm lesion and a 2.5 cm lesion bill differently. If the size isn't documented, the claim may not hold up.
Excision codes require documented lesion diameter plus margin width. The two measurements are used for code selection. Missing or incorrect margin documentation can lead to undercoding, overcoding, or payment issues.
Mohs codes (17311–17315) are based on stages, blocks, and anatomic site. Each stage has specific documentation requirements, making Mohs billing a specialized area within dermatology.
Dermatology claims often require strong medical necessity documentation. Acne treatment, laser therapy, and certain lesion removals may fall on the cosmetic line. Documentation must clearly support the medical reason for covered services.
When a dermatology practice sends a specimen to an outside pathology lab, professional and technical components may be split. When laboratory services are performed in-house, the coding workflow changes.
When a dermatologist performs a procedure during an office visit, modifier 25 may apply when the E/M service is separately identifiable and properly documented.
Psoriasis and atopic dermatitis biologics may require prior authorization tied to clinical criteria, failed prior therapies, and documented severity. Tracking authorizations helps prevent treatment interruptions and billing delays.
Dermatology coding updates annually, while payer requirements for biopsies, Mohs procedures, biologics, and other services can change over time.
Every claim goes through a six-step process designed to prevent denials before they happen.
We check coverage, co-pays, deductibles, and prior authorization requirements before the patient arrives. Cosmetic coverage and biologic benefits are verified separately where needed.
Every service including E/M visits, biopsies, destructions, excisions, Mohs stages, phototherapy, and patch testing — is converted into billable line items with the required documentation.
Certified coders apply CPT, ICD-10, and HCPCS codes with attention to lesion size and site, excision margins, Mohs stages and blocks, modifier 25, and other applicable modifiers.
Before submission, claims are reviewed for missing size documentation, margin errors, Mohs stage mistakes, medical necessity gaps, NCCI edits, and modifier problems. Clean claims are submitted within 24 hours.
ERA/EOB posting is matched against expected reimbursement. Underpayments on surgical and Mohs claims are identified and appealed when appropriate.
Denials are worked within 24–48 hours. Appeals include clinical documentation, coding rationale, and regulatory citations. Denial trends are tracked to identify and correct recurring issues.
Each dermatology procedure family has its own coding and documentation requirements.
Punch, shave, and excisional biopsies have different coding requirements. Site and technique must match the documentation.
Excision codes require documented lesion diameter and margin width. Accurate measurements support correct coding.
Code repairs according to length, complexity, and anatomic site.
Psoriasis and atopic dermatitis biologics may require prior authorization and J-code billing where applicable. Med Bridge LLC manages the related authorization and billing workflow.
Phototherapy and patch testing have frequency limits and documentation requirements that must be met for proper reimbursement.
Destruction codes depend on lesion type, size, and whether the lesion is benign or premalignant.
Mohs billing is based on stage, block, and anatomic site. Each stage requires appropriate documentation.
Teledermatology claims require appropriate POS coding and modifier 95 usage, with payer and state rules monitored as they change.
These numbers come from our active dermatology clients. We don't publish wishful benchmarks we publish results.
Prior authorization is especially important for biologics and Mohs surgery, where individual claims can involve significant reimbursement.
