Dermatology Billing Services
Denied claims and audit risks add up fast in dermatology. One wrong modifier or missing detail can cost you thousands.
Medhasty Billing fixes coding gaps, strengthens documentation, and keeps your claims clean from submission to payment.

A single dermatology visit often generates three or four procedure codes plus an E/M code and a pathology code. One wrong digit and the entire claim denies. Dermatology billing is not primary care billing. The volume is higher. The rules are tighter. The audit risk is real.
A lesion removal is medical if the lesion is suspicious, painful, or bleeding. The same removal is cosmetic if the patient wants it for appearance only. The difference is documentation. Payers deny claims without a clear medical indication.
A dermatologist sees 30 to 40 patients per day. Each visit generates multiple codes. More codes mean more chances for missing modifiers, incorrect measurements, and wrong code selection. Each error triggers a denial. Each denial costs staff time. Volume multiplies mistakes
The OIG audits dermatology more than most specialties. High volume. Complex coding. Subjective medical necessity decisions. Common audit findings include incorrect lesion size documentation, missing modifier 25, and unbundling of excision codes. Audits cost time and money. Proper billing prevents them.
Use 99202-99205 for new patients, 99212-99215 for established. Add modifier 25 when billing a procedure on the same day.
11102-11103 for tangential (shave) biopsies. 11104-11105 for punch biopsies. 11106-11107 for incisional biopsies. Each lesion gets its own code.
17110 for up to 14 benign lesions. 17111 for 15 or more. 11200 for skin tags (up to 15). 11201 for each additional 10 skin tags.
11400-11406 for benign lesions. 11600-11606 for malignant lesions. Code based on lesion diameter, not excision margin.
11300-11303 for trunk, arms, legs. 11305-11308 for face, ears, eyelids, nose, lips. Based on lesion diameter.
17311 for first stage (up to 5 blocks). 17312 for each additional stage. Includes pathology. Do not bill separate pathology codes.
Cryo for actinic keratoses is covered (17110-17111). Lasers for vascular lesions may be covered. Chemical peels for photoaging are cosmetic – not covered.
11900 for up to 7 injections. 10060 for simple cyst drainage. 10040 for acne surgery (comedone extraction).
Dermatology is an OIG audit target. Common findings include incorrect lesion measurement, missing modifier 25, unbundling, and lack of medical necessity.
We protect your practice with pre-bill documentation review, modifier validation, medical necessity checks, NCCI compliance, monthly internal audits, and provider education.
When auditors come, we provide the documentation they need. We respond within deadlines. We appeal adverse findings. We protect your revenue and your reputation.
We customize our services to your workflow, your payers, and your patients. No one-size-fits-all. Just dermatology billing that works for you.
Medicare covers medically necessary dermatology procedures with documented medical necessity. Follow NCCI bundling edits. Use correct modifiers. Mohs surgery requires specific tumor types and locations.
Commercial payers vary. Some require prior authorization for biopsies. Some limit biopsies per visit. Some have different bundling rules than Medicare. Check each plan.
Medicaid varies by state. Some states cover routine dermatology. Some cover only emergencies. Some require prior authorization for everything.

We work every denial within 48 hours. Correct. Resubmit. Track patterns. Prevent repeats.
We follow up on unpaid claims. Post payments daily. Reconcile against expected amounts. Flag underpayments.
Clear statements. Show what insurance paid. Show what patient owes. Collect faster.
In-house vs. outside lab – how billing changes completely
In-house pathology means the practice keeps 100 percent of reimbursement. Outside lab means the lab takes the technical component. Many practices send specimens out and lose revenue. Bring pathology in-house or contract with a pathologist to capture professional fees.
TC and 26 modifiers – are you splitting components correctly?
Global pathology = no modifier (practice owns lab and employs pathologist). Technical component only = TC (practice owns lab, outside pathologist reads slides). Professional component only = 26 (outside lab processes, practice pathologist reads).
88305 and the skin path codes – billed right every time
88305 is for standard skin biopsies (most common). 88307 is for complex cases (melanoma, special stains). 88309 is for large resections. Using the wrong level triggers denials or audits.
Cosmetic vs. Medical Dermatology Billing
Dermatology billing is complex. High volume. Strict rules. Real audit risk. But getting paid correctly is possible.
We handle your dermatology billing from eligibility to payment posting. We catch errors before claims go out. We work denials within 48 hours. We protect you from audits. You focus on patients.
FAQS
11400 series is for benign lesions. 11600 series is for malignant lesions. Use benign code initially. Update to malignant code after pathology confirms malignancy.
No. Modifier 25 is required on the E/M code. Without it, the payer bundles the E/M into the procedure and denies it.
Yes, using CPT 17110 or 17111. Documentation must show the lesions are actinic keratoses, not other benign lesions.
Both indicate distinct procedural service. XS specifically means separate structure (different anatomical site). CMS prefers X-modifiers over modifier 59 when they apply.
No. Medicare covers Mohs for specific tumor types (basal cell, squamous cell) on high-risk areas like the face and ears. Prior authorization is often required.
Lesion characteristics (size, shape, color), symptoms (pain, itching, bleeding), history of change, and clinical suspicion for malignancy. Not "patient requested removal."
