Dermatology Specialties We Support
From routine skin checks to Mohs micrographic surgery and biologic therapy infusions, every dermatology subspecialty has distinct coding rules, documentation standards, and payer challenges. Here is how ProvidaRCM addresses each.
Dermatology Revenue Challenges
Dermatology billing involves more procedure-level decision points per encounter than almost any other specialty. Each challenge below is a systematic source of revenue loss without specialty-specific billing processes.
High-Value Dermatology Billing Insights
Understanding where dermatology revenue is created, lost, and recoverable is the foundation of specialty-specific billing management.
Revenue Your Practice Is Not Capturing
Most dermatology practices have untapped billable revenue from services performed but not fully coded, multi-lesion encounters, repair complexity upgrades, and pathology coordination billing.
Denials Your Practice Should Never See
The majority of dermatology denials trace to predictable causes, missing modifiers, cosmetic/medical mismatch, and authorization gaps that systematic processes eliminate.
Documentation Gaps That Cost the Most
Lesion size, repair length, and Mohs stage/block counts must be precisely documented to support the CPT code billed, gaps here generate downgrades on audit.
Recovering What Payers Owe
Dermatology payments are frequently processed below contracted rates on multi-procedure claims due to incorrect multiple procedure reduction application.

Common Dermatology CPT Codes
Every dermatology CPT code billed by ProvidaRCM is reviewed against operative documentation, modifier requirements, and payer-specific criteria before submission.
| CPT Code | Description | Typical Use and Billing Notes |
|---|---|---|
| 99213 | Office visit, established patient, low complexity | Common general dermatology E/M. Time-based or MDM-based selection under 2021 guidelines. Modifier 25 required when billed same-day as a procedure. |
| 11102 | Tangential biopsy of skin, single lesion | Shave biopsy technique. Must match documented technique, punch biopsy is 11104, incisional is 11106. Add-on codes apply for each additional lesion. |
| 17000 | Destruction, premalignant lesion (e.g., actinic keratosis); first lesion | First lesion destroyed. Add-on 17003 for 2–14 additional lesions, 17004 for 15+. Lesion count must match documentation precisely. |
| 17110 | Destruction, benign lesions other than skin tags; up to 14 lesions | Benign lesion destruction. 17111 applies for 15+ lesions. Cannot be combined with 17000 series for the same lesion. |
| 11600 | Excision, malignant lesion, trunk/arms/legs; 0.5 cm or less | Size-tiered by excised diameter including margins, not pre-excision lesion size. Code selection scales with size up through 11606. |
| 17311 | Mohs micrographic surgery, first stage | Includes specimen processing and microscopic exam for the first stage. Add-on 17312 for each additional stage, 17315 for each additional block within a stage. |
| 17312 | Mohs surgery, each additional stage | Add-on code billed per additional stage beyond the first. Stage count must precisely match the Mohs surgical log documentation. |
| 14040 | Adjacent tissue transfer/rearrangement, eyelids, nose, ears, lips; 10 sq cm or less | Flap closure technique. Includes the lesion excision when performed in the same session, not separately billable with excision codes. |
| 12031 | Layer closure of wounds, scalp/extremities/trunk; 2.5 cm or less | Intermediate repair. Requires documented layered (subcutaneous + skin) closure. Simple closure included in excision code; complex repair uses 13100 series. |
| 88305 | Level IV surgical pathology, gross and microscopic exam | Common dermatopathology code. TC/26 split applies when lab equipment ownership differs from the billing dermatologist. |
| 96372 | Therapeutic injection, subcutaneous or intramuscular | Biologic injection administration. Drug billed separately under J-code. Modifier 25 applies when E/M is separately significant same day. |
Common Dermatology ICD-10 Codes
Diagnosis coding accuracy determines whether dermatology procedures meet payer medical necessity criteria. Every ICD-10 code must align with documentation and procedure billed.
| ICD-10 | Diagnosis | Billing Application Notes |
|---|---|---|
| C44.91 | Basal cell carcinoma of skin, unspecified | Primary indication for excision or Mohs surgery. Site-specific codes (C44.x) should be used when location is documented to strengthen medical necessity for the specific anatomical procedure. |
| C44.92 | Squamous cell carcinoma of skin, unspecified | SCC indication for excision, destruction, or Mohs. Pathology confirmation should precede billing of treatment procedures for this diagnosis to support medical necessity. |
| C43.9 | Malignant melanoma of skin, unspecified | High-acuity diagnosis requiring wide excision margins per treatment guidelines. Breslow depth and margin documentation strengthen medical necessity for excision size billed. |
| L57.0 | Actinic keratosis | Primary indication for cryotherapy and destruction codes (17000 series). Lesion count must be documented precisely to support the number of lesions billed. |
| L40.0 | Psoriasis vulgaris | Primary indication for biologic therapy authorization. Severity documentation (BSA percentage, PASI score) and topical/systemic therapy failure required for most biologic auth criteria. |
| L20.9 | Atopic dermatitis, unspecified | Common pediatric and adult dermatology diagnosis. Supports biologic therapy auth for moderate-to-severe cases with documented failure of topical treatments. |
| L70.0 | Acne vulgaris | Supports medical management billing. Isotretinoin management requires specific monitoring documentation. Cosmetic-only acne treatments should not be billed to insurance. |
| L71.9 | Rosacea, unspecified | Supports E/M and medical management billing. Subtype specificity (L71.0 perioral dermatitis, L71.1 rhinophyma) should be used when documented for procedure-specific billing. |
| L82.1 | Other seborrheic keratosis | Benign lesion, destruction billed under 17110/17111. Medical necessity requires documentation of irritation, bleeding, or diagnostic uncertainty rather than purely cosmetic concern. |
| L80 | Vitiligo | Supports medical management and phototherapy billing. Functional and psychosocial impact documentation strengthens medical necessity for treatment authorization. |
Common Dermatology Billing Modifiers
Modifier accuracy determines whether dermatology procedures are correctly reimbursed. ProvidaRCM validates every modifier before claim submission.
| Modifier | Description | Common Usage | Denial Risk |
|---|---|---|---|
| 25 | Significant, Separately Identifiable E/M Same Day | Required when E/M is billed same-day as a procedure (biopsy, destruction, injection) and is separately documented as significant beyond the procedure decision itself. | Very High |
| 50 | Bilateral Procedure | Applied when the same procedure is performed bilaterally, bilateral lesion excision at symmetric sites in the same session. | High |
| 51 | Multiple Procedures | Applied to secondary and subsequent procedures when multiple distinct procedures are performed in the same session, common in multi-lesion encounters. | High |
| 58 | Staged or Related Procedure During Postop Period | Applied when a planned staged procedure occurs during another procedure's global period, common in multi-stage reconstruction following Mohs surgery. | Moderate |
| 59 | Distinct Procedural Service | Overrides NCCI bundling when procedures are genuinely distinct, different lesion sites or separate sessions. Requires documentation justification. | Moderate |
| 76 | Repeat Procedure by Same Physician | Applied when the same procedure is legitimately repeated same-day by the same physician, repeat destruction after incomplete initial treatment. | Moderate |
| RT | Right Side | Site-specific modifier required by Medicare for laterality-dependent dermatology procedures on the right side of the body. | High, Medicare |
| LT | Left Side | Site-specific modifier required by Medicare for laterality-dependent procedures on the left side. Used with modifier 50 for bilateral billing per payer preference. | High, Medicare |
Prior Authorization in Dermatology
Biologics, phototherapy, and advanced procedures all carry distinct authorization requirements. ProvidaRCM manages the complete workflow for each.
Where Dermatology Revenue Disappears
These leakage patterns represent systematic, recurring losses that compound monthly across a dermatology practice's full claim volume.
Complete Dermatology Billing Services
Every service in the dermatology revenue cycle, delivered by billers trained specifically in skin procedure coding and pathology coordination.
Dermatology Provider Credentialing
Credentialing Determines What You Can Bill
Every new dermatologist, every new commercial payer relationship, and every hospital affiliation requires credentialing before claims can be submitted. ProvidaRCM manages the complete process from application to active billing status.
Timeline Guidance
Commercial payer credentialing typically takes 60–120 days. ProvidaRCM initiates credentialing 90 days before an expected practice start date.
Why Generic Billing Companies Struggle With Dermatology
Dermatology billing involves more procedure-level decisions per visit than most specialties. Generalist billers make systematic errors that compound across every claim of the same type.
In-House Billing vs. ProvidaRCM
The true cost of in-house dermatology billing includes salary, training, and the revenue lost to expertise gaps on Mohs and biologic claims.
| Category | In-House Dermatology Billing | ProvidaRCM |
|---|---|---|
| Total Cost | Salary + benefits + training + software, fixed cost regardless of volume | 2.49% of net collections, all-inclusive, scales with revenue |
| Dermatology Expertise | General billers without Mohs, pathology, or biologic training | Dermatology-specific billers trained in skin procedure and biologic coding |
| Mohs Surgery Billing | Stage/block counts billed without surgical log cross-reference | Every Mohs claim verified against surgical log before submission |
| Cosmetic/Medical Split | Cosmetic services occasionally billed to insurance, compliance risk | Dedicated cosmetic workflow separate from insurance billing |
| Biologic Auth Tracking | Renewal cycles missed, denied high-cost drug claims | Automated renewal tracking per patient per payer |
| Modifier Accuracy | Modifier 25, 50, 51 applied inconsistently | Every claim reviewed for modifier accuracy before filing |
| Denial Management | Mohs and biologic denials often left unappealed | Every denial appealed with specialty documentation support |
| Scalability | Adding providers requires new hiring and training overhead | Scales immediately as provider count and volume grow |
