Expert Medical Billing for Dermatology Practices
Dermatology billing presents unique challenges: precise cosmetic vs. medical coding distinctions, complex Mohs surgery reimbursement, and high insurance denial rates. Our specialists navigate these complexities to maximize your practice revenue.
Critical Dermatology Billing Challenges
Cosmetic vs. Medical Procedure Coding
Dermatology practices frequently struggle with the critical distinction between cosmetic and medical procedures. Miscoding cosmetic treatments (botox, fillers, laser skin resurfacing for wrinkles) as medical procedures, or failing to properly document medical necessity for medically necessary skin treatments, results in denials, audits, and potential recoupment demands from payers.
Mohs Surgery Billing Complexity
Mohs micrographic surgery requires precise coordination between pathology, laboratory analysis, and surgical services. Incorrect use of 17000-17004 codes, missing documented tissue levels, failure to report secondary closures appropriately, or improper pathology billing coordination frequently leaves significant revenue on the table.
Pathology Services Integration
Dermatological pathology requires clear separation between facility pathology, professional pathology interpretations, and slide preparation fees. Overlapping billing, missing modifier usage (-26, -TC), or inadequate coordination with pathology labs creates compliance risks and payment disputes.
High Denial Rates for Cosmetic Procedures
Insurance carriers routinely deny cosmetic procedures, even when medically necessary. Insufficient medical necessity documentation, inadequate pre-approval processes, and lack of comprehensive prior authorization requests result in unexpected patient financial responsibility and collection challenges.
Laser Treatment Code Selection
CPT codes for laser treatments (17000-17004 for destructive procedures, 96920-96922 for non-destructive treatments) are frequently misapplied. Incorrect laser code selection, failure to report multiple lesions appropriately, or mixing destructive and non-destructive modalities in the same session causes systematic underpayment.

Dermatology Billing FAQs
How do I determine if a skin treatment is cosmetic or medical?
Medical necessity documentation is critical. A procedure is typically considered medical if it treats a disease, injury, or pathological condition. For example, laser treatment for acne scars may be cosmetic, but laser treatment for acne vulgaris (active disease) may be medical. The documentation must clearly link the treatment to a diagnosed medical condition, not solely aesthetic improvement.
What documentation is required for Mohs surgery billing?
Mohs surgery requires detailed operative notes including: number of tissue levels examined, location and size of lesion, type of lesion/histology, margins status (clear or involved), reconstruction method, and skin pathology interpretation. Each component must be separately documented to support the surgical codes and pathology billing.
How should I bill pathology services with dermatological procedures?
Pathology services include technical component (tissue processing, staining, slide preparation) and professional component (pathologist interpretation). Use appropriate modifiers (-TC for technical, -26 for professional) to separately identify each component. Coordinate with your pathology lab or reference facility to prevent duplicate billing.
Can cosmetic procedures ever be covered by insurance?
In limited cases, yes. If a cosmetic procedure treats a diagnosed medical condition (functional impairment, scarring from injury/surgery, breast reconstruction after mastectomy), insurance may cover it. However, purely cosmetic treatments (wrinkle reduction, aesthetic enhancement) are typically patient-responsibility. Always verify coverage in advance.
What is the most common coding mistake in dermatology billing?
The most common error is incorrect laser code selection. CPT 17000-17004 are for destructive procedures (ablation, destruction). CPT 96920-96922 are for non-destructive treatments (skin rejuvenation, phototherapy). Using the wrong code set dramatically impacts reimbursement. Always verify the specific laser wavelength and treatment intention.
How do I handle prior authorization for dermatological procedures?
Many payers require pre-authorization for surgical procedures and some medical necessity procedures. Obtain the specific payer's prior authorization requirements before treatment. Include: clinical diagnosis, treatment plan, medical necessity justification, anticipated costs, and operative notes if revision. Document all authorization approvals for claims submission.
What modifiers do I need for Mohs surgery with reconstruction?
Use modifiers carefully: -51 for bilateral procedures, -52 for reduced services (partial procedures), -58 for staged procedures, -76 for repeat procedures by same physician, -77 for repeat procedures by different physician. For Mohs with reconstruction: bill surgical codes separately from reconstruction/closure codes. Never bundle Mohs and reconstruction as one code.
How should I code multiple lesions treated in one session?
For multiple lesions: code the first lesion separately, then add modifiers for additional lesions of the same type/location. For example: code the first lesion as 17000, then add 17001 for each additional lesion. If lesions are in different body areas or of different types, separate codes may be required. Always verify the specific CPT code instructions for additivity rules.
What's the difference between destructive and non-destructive laser treatments?
Destructive laser treatments (CPT 17000-17004, 17280-17286) physically ablate or destroy tissue (removing precancerous cells, treating actinic keratosis). Non-destructive treatments (CPT 96920-96922) use laser for phototherapy, skin rejuvenation, or non-ablative effects without destroying the tissue. The treatment intention and laser type determine the correct code.
How do insurance companies determine if a cosmetic procedure is medically necessary?
Payers use specific criteria: documented diagnosis of medical condition, treatment options considered, statement of medical necessity from provider, functional impairment documentation, and comparison to payer's medical necessity guidelines. Some payers have specific diagnosis codes they cover; others require case-by-case review. Always check the specific payer's policy before treatment.
Navigating Insurance Coverage for Dermatology
Typically Covered (Medical Necessity Required):
- Mohs micrographic surgery for skin cancer
- Laser treatment for acne vulgaris and severe active acne
- Treatment of precancerous lesions (actinic keratosis)
- Surgical removal of malignant and benign lesions
- Dermatological treatment of documented medical conditions
Typically Not Covered (Cosmetic):
- Botox and dermal fillers for cosmetic purposes
- Laser skin resurfacing for wrinkles and aging skin
- Chemical peels for aesthetic improvement
- Hair removal for cosmetic purposes
- Spider vein treatment (unless causing functional impairment)
Prior Authorization for Biologic Treatments
Many biologic treatments for dermatological conditions (psoriasis, atopic dermatitis, eczema) require prior authorization. Key requirements typically include:
- ✓ Documentation of prior treatment failures or contraindications
- ✓ Clear diagnosis and severity assessment
- ✓ Clinical indication and expected outcomes
- ✓ Cost-effectiveness analysis comparing treatment options
- ✓ Projected duration of treatment
Inadequate prior authorization requests significantly delay treatment initiation and increase patient frustration. Our specialists manage this complex process to expedite approvals.
