Dermatology Credentialing Services

Our Dermatology Credentialing Process

Step 1: Scope-of-Practice & Taxonomy Analysis — We map your full clinical scope — medical derm, surgical derm, Mohs, dermatopathology, phototherapy — against taxonomy codes. General dermatology (207N00000X) covers office visits but may not authorize Mohs billing. Mohs subspecialty (207NS0135X) must be specified for payers that gate surgical dermatology procedures. We set the taxonomy correctly at CAQH and NPI level before any application goes out.

Step 2: CAQH Profile Build With Procedural Detail — Your CAQH profile is configured with every procedure category you perform, including in-office surgery indicators, lab services (if applicable), and any subspecialty board certification (Mohs, dermatopathology). Payers pull procedure authorization from CAQH; incomplete procedural data means claims deny for services you are credentialed to provide in theory but not flagged for in the system.

Step 3: CLIA Coordination for In-Office Labs — Dermatology practices performing in-office dermatopathology or KOH preps need CLIA certification aligned with their payer enrollment. We coordinate CLIA waiver or certificate of compliance alongside payer applications so lab billing is authorized from the same effective date as your provider enrollment.

Step 4: Multi-Payer Parallel Submission — All target payers submitted simultaneously — Medicare (with surgical procedure authorization), Medicaid, and every commercial payer. Dermatology-specific considerations: some PPO networks restrict Mohs to fellowship-trained dermatologists; some HMO products require referral authorization for dermatologic surgery. We know which networks gate which procedures.

Step 5: Surgical Privilege Verification — Payers that reimburse Mohs and excisional surgery typically require documentation of surgical training — fellowship completion, case logs, or board certification in Mohs surgery. We prepare this documentation package alongside the standard credentialing application so surgical privileges are granted on the first pass.

Step 6: Billing Activation & Code Verification — Upon approval, we verify that your payer enrollment authorizes the full range of CPT codes you bill — including Mohs stages (17311-17315), destruction codes (17000-17286), biopsy codes (11102-11107), and dermatopathology interpretation (88305). Your billing team receives a payer-by-payer procedure authorization matrix.

Benefits of Professional Dermatology Credentialing

• Taxonomy precision — correct subspecialty taxonomy (Mohs, dermatopathology) set at NPI and CAQH level so procedure billing is authorized
• Mohs surgical privileges — fellowship documentation and case logs prepared alongside credentialing application
• CLIA lab coordination — in-office dermatopathology lab certification aligned with payer effective dates
• Full procedure-code authorization — Mohs stages, destructions, biopsies, and path interpretation verified as billable per payer
• Cosmetic vs covered services — payer-specific rules on cosmetic exclusions navigated so covered procedures are not mistakenly excluded
• Multi-location practices — dermatology groups with satellite offices credentialed at every location for every payer
• Teledermatology enrollment — store-and-forward and live video dermatology credentialing where payers accept asynchronous modalities
• a 99.4% first-time approval rate — subspecialty documentation audited before every submission prevents surgical-privilege denials

Compliance Considerations

• Mohs surgery oversight — CMS and some commercial payers have specific coverage determination policies for Mohs; billing outside LCD/NCD criteria triggers audits
• CLIA requirements — dermatopathology performed in-office requires the appropriate CLIA certificate; billing lab codes without CLIA certification risks sanctions
• Cosmetic exclusion policies — payers have specific lists of procedures considered cosmetic; coding a covered procedure incorrectly can trigger recoupment
• Supervision requirements — mid-level providers (PAs, NPs) in dermatology must meet state and payer supervision rules; incident-to billing has specific documentation requirements

Typical Timelines

• Medicare PECOS — 45-90 days; Mohs authorization typically included for board-certified Mohs surgeons
• Commercial payers — 60-120 days; some require separate surgical privilege review adding 2-4 weeks
• Medicaid — 30-120 days by state; procedural restrictions vary significantly by state program
• CLIA certification — 2-4 weeks for waiver; 8-12 weeks for certificate of compliance

Common Mistakes We Prevent

• Generic taxonomy code — using 207N00000X (general derm) when 207NS0135X (Mohs) is needed; Mohs procedure claims deny
• Missing CLIA for in-office lab — billing dermatopathology without the matching CLIA certificate; triggers Medicare sanctions
• Incomplete surgical documentation — not including Mohs fellowship certificate or case logs; payer denies surgical privileges and you must reapply
• Cosmetic coding errors — coding a medically necessary procedure with a cosmetic diagnosis; triggers denial and potential audit
• Not credentialing satellite offices — each practice location must be separately enrolled; claims from uncredentialed locations deny
