Dermatology Medical Billing & Coding to Maximize Revenue

We know running a dermatology practice is not easy. It can be complicated for you if you are balancing patient care with insurance claims, coding accuracy, and revenue management simultaneously. When you get paid correctly and on time should not feel like solving a puzzle every day. However, many dermatology practices lose thousands of dollars annually due to coding errors, claim denials, or simply missing charges for procedures performed.

Dermatology medical billing is not like normal medical billing; it takes special know-how. Codes change often, each insurance company has its own rules, and even a small error can delay payment for weeks.

This guide walks you through everything you need to know about dermatology billing and coding, from understanding common procedure codes to choosing the right support for your practice.

What Is Dermatology Medical Billing & Its Role

Dermatology medical billing is the process of translating dermatology services like consultation, biopsies, excisions, Mohs micrographic surgery, and acne treatments into accurate claims submitted to insurance companies for reimbursement.

What do dermatology billing specialists do?

Billing for dermatology isn’t just about sending claims. It includes:

• Picking the correct CPT and ICD-10 codes
• Checking patient insurance eligibility
• Submitting clean claims
• Following up on unpaid or denied claims
• Posting payments and handling patient balances

Dermatology medical billing is different from traditional medical billing because dermatology is more complex, as a single patient visit might involve multiple procedures a skin exam, biopsy and cryotherapy. All of these processes require their own code with specific modifiers. The accurate claims are important because when you don’t submit them correctly, it can lead to denial or delayed payments, longer accounts receivable times, compliance and audit issues

Did you know:
According to industry data, dermatology practices face denial rates ranging from 5% to 15%, often due to coding specificity issues. That’s significantly higher than many other specialties. Having a specialized dermatology billing service can dramatically reduce these denials.

Dermatology CPT and ICD-10 Codes Explained:

Mastering codes is key to successful dermatology medical billing and coding. CPT codes describe procedures, while ICD-10 codes pinpoint diagnoses. In 2025-26, updates from the AMA and CMS introduce refined codes for better specificity, like expanded subtypes for skin cancers.

ICD-10 Codes for Skin Conditions

Matching ICD-10 for dermatology with CPT codes ensures clean claims. Common examples:

• Actinic keratosis: L57.0
• Basal cell carcinoma: C44.9 (unspecific site), C44.99 (specific sites)
• Acne vulgaris: L70.0 (common form)
• Psoriasis: L40.0-L40.9 (various types)
• Atopic dermatitis: L20.0-L20.9 (ranging from infantile to unspecified)

The connection between diagnosis and procedure codes must be clinically logical. For example, billing CPT 11102 (skin biopsy) with ICD-10 L70.0 (acne) would likely trigger a denial unless the biopsy was unrelated to the acne diagnosis.

Dermatology Medical Coding and Billing Workflow:

A well-structured workflow ensures that clinical services translate into clean, approvable claims. Here’s the essential process:

1. Patient Registration & Insurance Verification:

Before the patient arrives, verify insurance eligibility and secure prior authorizations for procedures like biopsies or specialized treatments.

2. Clinical Documentation:

Provider must document:

• Chief complaint and history
• Examination findings (lesion size, location, number)
• Medical necessity for each procedure
• Time spent on evaluation and management services

3. Charge Capture and Code:

Our in-house Certified dermatology medical coders translate documentation into accurate codes. This step requires specialized knowledge. General coders often miss dermatology-specific nuances. Charge entry services must capture every billable procedure, including supplies and pathology referrals

4. Claim Submission:

Submit clean claims electronically with proper modifiers. For example, modifier -59 indicates distinct procedural services, crucial when performing multiple procedures during one visit.

5. Payment Posting

Payment posting provides insights into reimbursement trends, helping identify underpayments.

6. Denial Management:

Analyze causes of denials and resubmit corrected claims.

7. Patient Billing & Collections:

Manage patient balances and offer payment options.

Payment Plans and Financial Options for Dermatology Clinics:

Patient affordability is a growing concern. Offering a dermatologist payment plan can improve collections while enhancing patient satisfaction.

How Payment Plans Help

• Reduce upfront financial stress for patients

Common Challenges in Dermatology Billing

High Claim Denial Rates

Coding errors, missing modifiers, or incomplete documentation often lead to denied claims.

Cosmetic vs. Medical Billing Confusion

Incorrectly billing cosmetic procedures as medically necessary can cause denials or patient disputes.

Undercoding and Missed Charges

Procedures like biopsies or excisions may be undercoded or not billed at all, leading to lost revenue.

Frequent Coding and Payer Rule Changes

Constant updates to CPT codes and payer policies make it difficult to stay compliant.

Delayed Payments and Poor Cash Flow

Unpaid or slow-paying claims increase AR days and disrupt predictable revenue.
