Are you still struggling to manage dermatology billing and coding? MedCare MSO delivers dermatology billing services from certified derm coders who know lesion coding, modifier rules, and how multi-procedure visits actually work, backed by dermatology denial management that cuts denials and gets you paid faster.
Book A Free ConsultationDermatology practices running high procedure volume need dermatology billing services that hold up to strict modifier and medical necessity guidelines. Errors can lead to denials that add up over time and cause revenue loss. This is what a specialized dermatology billing company can offer when proper claim coding and scrubbing practices are applied.

Dermatology bills more procedures per visit than almost any specialty. A single patient may need a biopsy, a destruction, and a same-day E/M on a single claim. Each of these carries a modifier rule and a medical necessity threshold that has to hold on its own. Here is where practices lose revenue.
Even a single appointment could involve performing an exam, biopsy, and destruction, all of which require their own CPT coding, modifiers, and medical necessity. Forgetting one detail can bundle or deny the whole claim
A benign lesion removed because it bleeds or hurts is covered, but the same removal for appearance is cosmetic and patient billed. Documentation and diagnosis coding decide which way the procedure gets paid.
Same-day E/M plus a procedure needs modifier 25, and separate lesions or sites need modifier 59 or XS to clear NCCI edits. If modifiers are inappropriately coded, then services that should be billed separately will be billed together.
Excision CPT is chosen by lesion size plus margins and by the site. The size has to be measured and documented before excision, margins included, because each size tier pays differently. A measurement taken after removal, or a note missing margins, downcodes the claim and shorts the reimbursement.
Stage-by-stage Mohs billing requires precise documentation at every stage of the procedure, including defect size and method of repair employed. If anything is missed, the facility loses out on the revenue of surgical and reconstructive procedures.
NCCI edits group together multiple same-day pairs, and procedures carry global periods. Staged work uses modifier 58, unrelated same-global visits use modifier 24, and unrelated procedures use modifier 79.
Get Started TodayWe run full dermatology revenue cycle management to help you capture more of what you've earned while staying audit-ready. Each step below connects into one accountable workflow:
We bill E/M visits and minor procedures with the diagnosis specificity payers require for medical necessity including for acne (L70.0), psoriasis (L40.x), dermatitis (L20.x–L30.9), and rosacea (L71.x).
Biopsies, excisions, destructions, and repairs are coded based on the technique used, site of the procedure, and excised size, with intermediate and complex closures reported separately. Diagnosis carries the claim e.g. D22.x/D23.x supports benign excisions and C43.x and C44.x support malignant ones.
Mohs surgery billing (CPT 17311–17315) follows a staged approach, where code selection considers stage and number of tissue blocks. Same-day reconstruction is coded separately, and modifier 58 applies when a planned repair falls within the global period of a related prior procedure. The surgeon or pathologist hybrid complicates the frozen-section pathology coding process, but our coders know how to deal with it.
Most routine dermatopathology specimens are Level IV (88305); a narrower set, skin cyst, tag, and debridement specimens, falls to Level III (88304). When the lab and reading are split, the technical and professional components (TC/26) are billed separately, and component errors are a common source of unpaid or short-paid claims.
Most cosmetic procedures do not have special coverage, so the risk is compliance and not coding. We bill patients according to their responsibility and apply the ABN workflow with GA/GX/GY/GZ modifiers.
Pediatric derm brings age-specific diagnosis coding for conditions like infantile hemangiomas, molluscum, and atopic dermatitis. It also adds consent and guarantor considerations that adult-focused billing teams routinely miss, so we build them into the workflow.
Synchronous video visits and store-and-forward consultations have different rules: POS codes 02 and 10, modifier 95, and coverage and payment-parity rules that vary by payer. We apply each payer's telehealth rules so your virtual-visit revenue stays as clean as your in-person consultations.
Bill a sub-specialty we didn't list, or a mix of them? We handle the full range.
Schedule a CallbackOur dermatology coding services handle each and every one of these code types every day, which is what distinguishes dermatology specialty billing services from other generic teams.
Accurate dermatology coding services start with the right reference. These codes are just a few examples of dermatology codes, and a certified coder must check them all against the current AMA CPT and ICD-10 edition. The rules of coverage comply with CMS and Medicare contractor regulations, and the clinical recommendations are guided by American Academy of Dermatology.
| CPT code / range | Service | Revenue & denial note |
|---|---|---|
| 99202–99215 | E/M office visits | Payers audit modifier 25 here more than anywhere else in derm; the visit note must stand on its own or the E/M gets bundled into the procedure. |
| 11102–11107 | Skin biopsy (tangential, punch, incisional) | Only one primary biopsy code per day; extra lesions take add-on codes, and billing two primaries is routinely denied. |
| 11400–11446 | Excision, benign lesions | Reimbursement jumps at each size tier, so unmeasured margins mean silent downcoding on every claim. |
| 11600–11646 | Excision, malignant lesions | Hold until pathology confirms malignancy; billing malignant on a benign result invites recoupment. |
| 12001–13160 | Wound repair (simple, intermediate, complex) | Simple repair is bundled into the excision; intermediate and complex pay separately only when layered closure is documented. |
| 17000, 17003, 17004 | Destruction of actinic keratoses | Count lesions precisely: 17000 for the first, 17003 each for 2–14, 17004 flat for 15+, and undercounting is unclaimed revenue. |
| 17260–17286 | Destruction of malignant lesions | Site and size select the code; these carry global periods, so follow-up visits need modifier 24 to get paid. |
| 17311–17315 | Mohs micrographic surgery | Stage and block counts must be in the op note; missing block documentation is the top Mohs audit finding. |
| 96910–96913 | Phototherapy (UVB / PUVA) | Most payers cap visit frequency and require documented response; auth lapses mid-course are a common denial. |
| 95044 | Patch testing | Paid per antigen, so the claim must state the number tested; unlisted counts get denied or paid for one. |
Our dermatology billing services connect to a complete AI ecosystem that runs the derm revenue cycle from the exam note to the posted payment. Take the full stack as an all-in-one solution, or connect a single piece to the platform you already run.
Centralizes dermatology records with clinical workflows that feed charge capture the moment an encounter is documented.
Captures lesion sites, sizes, and biopsy counts as structured documentation at the point of care, so coders confirm the details that drive excision and destruction codes.
Assists with dermatology CPT, ICD-10, and modifier assignment under certified coder review, flagging modifier 25 and 59 opportunities before a claim bundles.
Runs scheduling, eligibility, and claims from one platform, with dashboards on collections by procedure type and denials by payer for your derm practice.
We bill inside the platform your practice already runs, with no migration. That includes dermatology-native systems like ModMed EMA, Nextech, and EZDERM, plus general platforms from Epic and eClinicalWorks to AdvancedMD, Kareo and Tebra, DrChrono, athenahealth, and NextGen. Our coders know where each stores biopsy counts, lesion sites, and modifier flags.
Dermatology coverage shifts by payer. Medicare sets lesion and biopsy rules through local coverage determinations that vary by MAC, Medicaid adds prior authorization triggers, and commercial carriers publish their own medical necessity policies. We match diagnosis to procedure against the applicable LCD or NCD, apply an ABN when a service reads as cosmetic, and bill Aetna, Blue Cross Blue Shield, UnitedHealthcare, Cigna, and Humana.
Dermatology has its own MIPS measures, such as melanoma coordination of care and timely biopsy result reporting, and choosing the wrong ones costs points before the year even starts. We help your practice select the measures that fit its procedure mix, capture the quality data inside the billing workflow rather than as separate chart abstraction, and track performance thresholds through the year, so everything is documented accurately ahead of attestation. Final payment adjustments are set by CMS based on your MIPS score.
Dermatology charts carry clinical photographs, including full-face images that are themselves PHI identifiers, so data security is not optional paperwork. Operations run under HIPAA and SOC 2 Type II controls, with encryption in transit and at rest, role-based access to every chart, and recurring staff security training. We support the audits dermatology practices actually face, from TPE and RAC to UPIC reviews and ADR requests, with organized documentation ready when a records request arrives, and AAPC and AHIMA-certified coders handling your coding throughout.
Plenty of billing companies will take a dermatology client. Far fewer can handle Mohs surgery billing stage by stage, defend a modifier 25 under audit, or tell a payer why a symptomatic seborrheic keratosis is not cosmetic. Practices that outsource dermatology billing to MedCare MSO get specialty-trained teams backed by the infrastructure we bring to 50+ specialties and practices of every size nationwide.
In-house billing keeps claims with your own staff, so tracking payer rule changes, dermatology coding, and denials falls on them too. Outsourced dermatology billing services move that load to a specialty team. When you outsource dermatology billing to MedCare MSO, you get specialized coders and billing experts who handle dermatology medical billing end-to-end, processing claims faster and managing denials promptly.
Dermatology medical billing is the process of coding and submitting claims for dermatology services, from office visits and biopsies to excisions, Mohs surgery, and pathology. It requires specialty knowledge of lesion coding, modifier rules, and the cosmetic versus medically necessary distinction that drives coverage.
Modifier 25 is used when a significant, separately identifiable evaluation and management service is performed on the same day as a procedure. In dermatology, this often applies when a provider evaluates a new problem and performs a biopsy or destruction in the same visit.
Mohs surgery billing uses codes 17311 to 17315 based on the anatomic site and the number of stages performed. Same-day repairs are coded separately. Pathology is included in the Mohs codes, so it is not billed separately for tissue examined during the procedure.
Cosmetic dermatology procedures such as Botox for wrinkles, fillers, and elective laser treatments are generally not covered by insurance and are billed to the patient. When a similar service treats a documented medical condition, it may be covered, so accurate diagnosis coding and documentation are essential.
Common dermatology denials include a missing or incorrect modifier 25 or 59, insufficient medical necessity documentation, NCCI bundling of same-day procedures, missing prior authorization, and incomplete lesion documentation such as size, margins, or anatomic site.
Most dermatology billing companies charge a percentage of monthly collections, which varies with claim volume, sub-specialty mix, and scope of services. MedCare MSO's dermatology billing services typically range from 3 to 7 percent of monthly collections, and a free billing audit shows the expected return before you commit to anything.
Yes. You keep full ownership of your data and complete visibility into every claim. With MedCare MSO you get live dashboards showing collections, denials, and A/R in real time, so outsourcing removes the workload without handing over control of your revenue.
Most dermatology practices transition within two to four weeks. We map your workflow, connect to your systems, and run a parallel period so claims keep flowing during the handoff, with your existing accounts receivable worked alongside new claims so nothing is dropped.
