How We Help
Dermatology Billing Work We Handle
Thrive manages the billing side of your dermatology practice so your physicians can stay focused on patients instead of chasing payers. That means coding every biopsy, destruction, and excision by the correct procedure family, applying modifier 25 correctly when an E/M visit and a procedure happen the same day, and following up on every claim until it is paid or resolved.
Practices that choose dermatology medical billing company support from Thrive get a team that already knows lesion coding, Mohs staging, and biologic prior authorization, instead of a generalist biller treating every skin procedure the same way. Whether your practice is general dermatology, a Mohs surgery practice, or a mix of both, the coding rules overlap enough to share one trained team and diverge enough that generalist billers consistently get them wrong.

Dermatology Medical Billing and Coding
End-to-End Dermatology Revenue Cycle Management
Dermatology billing services carry more procedure variety per visit than most specialties, biopsy, destruction, excision, pathology, and drug administration can all show up in a single encounter. Here is what we handle from the first eligibility check to the final payment.
Eligibility & Benefit Verification
Prior Authorization
Secures and tracks authorization for biologic therapies, photodynamic therapy, and Mohs surgery across commercial and Medicare Advantage plans.
Claims Submission & Scrubbing
Checks every biopsy, destruction, and excision code against lesion count, size, and modifier requirements before a claim leaves the building.
Denial Management & Appeals
Traces denials to their actual cause, whether a cosmetic reclassification or a missing modifier 25, and appeals with the documentation each payer requires.
AR Follow-Up
Works open claims on a set schedule so biopsy, excision, and biologic balances do not sit past 30 days unattended.
Patient Statements & Collections
Bills patients clearly for procedures payers classify as cosmetic, backed by proper documentation and ABN forms where required.
Payment Posting & Reconciliation
Reconciles biologic drug reimbursement against the actual dose administered, so cost overruns get caught early.
Credentialing & Payer Enrollment
Keeps dermatologists and Mohs surgeons credentialed and enrolled with the payers your patients actually carry.
Reporting
Regular reporting on claim status, denial trends, and AR aging broken out by procedure, biologic, and pathology claim categories.

What is the difference between destruction, biopsy, and excision?
A biopsy samples tissue to reach a diagnosis and is coded by technique, shave, punch, or incisional. Destruction ablates a lesion in place, such as with cryotherapy or electrosurgery, and is coded by lesion count. Excision removes a lesion with a margin of surrounding tissue and is coded by the excised diameter, not the lesion size alone. Billing the wrong family for what was actually done is one of the most common reasons dermatology claims underpay.
Why does the same procedure get billed differently depending on diagnosis?
Dermatology coverage often depends more on the pathology result than the procedure itself. A lesion excised and later confirmed malignant on pathology is billed and covered differently than the same excision on a lesion that turns out to be a benign cyst, which some payers treat as cosmetic. Coding has to align with the pathology result rather than assuming coverage in advance.
Denial Patterns
What Causes Dermatology Claims to Get Denied
These are not generic billing problems. Each one is specific to how payers adjudicate dermatology and Mohs surgery claims.
Cosmetic vs. Medical Necessity Denials
The same excision covered when pathology confirms a malignancy gets denied as cosmetic when the same lesion turns out to be a benign cyst, even though the procedure performed was identical.
Missing Modifier 25 on Same-Day E/M
Billing an office visit on the same day as a biopsy or destruction without modifier 25, and without documentation showing the visit was separately identifiable, is one of the most common and costly dermatology denials.
Lesion Count and Add-On Code Errors
Billing the base biopsy or destruction code multiple times instead of using the correct add-on code for each additional lesion triggers an automatic denial under payer editing rules.
Excision Size Measured Incorrectly
Coding an excision by lesion size alone instead of the excised diameter, measured before anesthesia and including margins, systematically undercodes malignant excisions and underpays the practice.
Mohs Surgery Documentation Gaps
Missing stage-by-stage margin documentation, or performing Mohs on a small, low-risk lesion that does not meet medical necessity criteria versus standard excision, both lead to denial or recoupment.
Biologic Prior Authorization Denials
Psoriasis, atopic dermatitis, and hidradenitis suppurativa biologic claims are denied without documented step therapy failure, body surface area, and functional impairment on file before the prior authorization request.
Missing JW or JZ Modifier
Biologic and skin substitute drug claims submitted without a JW modifier for discarded drug or a JZ modifier confirming zero waste are treated as missing required information and denied.
Pathology Bundling Errors
Billing surgical pathology separately when it is already included in the Mohs code, or missing the technical and professional component split when an outside lab processes the specimen, causes denial or overpayment exposure.
Our Process
How Our Dermatology Billing Process Works
Every step below exists because of a specific denial pattern above. Nothing here is generic.
Eligibility & Prior Auth Clearance
We confirm coverage and secure authorization for biologics, phototherapy, and Mohs surgery before the date of service, so a missing prior auth never becomes a denied claim after the fact.
Dermatology-Trained Coding Review
Every claim is coded by billers who distinguish biopsy, destruction, and excision families and track lesion counts daily, not generalists rotating across unrelated specialties.
Pre-Submission Modifier & Edit Scrubbing
Claims are checked for modifier 25, correct add-on codes, and JW or JZ requirements before they reach a payer, catching the errors that cause the most denials.
Clean Claim Submission
Corrected claims go out within 48 hours, keeping your dermatology billing cycle moving instead of sitting in a queue.
Denial Root-Cause & Appeal
Any denial is traced to its actual cause, a cosmetic reclassification, a missing modifier, or a biologic authorization gap, and appealed with the documentation that specific payer requires.
AR Follow-Up & Reporting
Outstanding claims are worked on a set follow-up schedule until resolved, with regular reporting back on where your numbers stand.

FAQ
Dermatology Billing FAQs
How much does dermatology medical billing cost?
Fee structures are typically based on a percentage of collections and are set after we review your claim volume and procedure mix, since a Mohs and biologic heavy practice bills very differently than a general dermatology office. You get a custom fee schedule after your Free 15-Minute Practice Revenue Review, with no obligation to sign anything.
How long does onboarding take?
Most dermatology practices are fully onboarded within one to two weeks. We start with a free billing audit to see where claims are getting stuck, then align our coding and submission workflow to your current documentation process, with no disruption to your daily schedule during the switch.
Can you take over our existing AR and open claims?
Yes. We review your open AR, including anything already aged past 30 or 60 days, and prioritize the claims most likely to be recovered first. Older excision, Mohs, and biologic claims often still qualify for appeal well past their original denial date.
Do you bill Mohs surgery and biologic claims correctly?
Yes. Our coders track Mohs stages and tissue blocks separately from pathology billing, apply modifier 25 correctly on same-day E/M visits, and manage JW and JZ modifiers on biologic drug claims so dose and waste are documented the way payers require.
How do you handle denied claims and appeals?
Every denial is traced back to its actual cause, a cosmetic reclassification, a missing modifier 25, or a biologic prior authorization gap, before we resubmit anything. We then file the appeal with the documentation that specific payer requires, rather than resending the same claim and hoping for a different result.
Is our patient data handled securely?
Yes. Patient data is handled under HIPAA safeguards across intake, coding, and reporting, and our billing team follows the same compliance standards regardless of practice size or claim volume.
How do we track our numbers?
You receive regular reporting covering claim status, denial trends, and AR aging, plus a direct line to your billing team any time you have a question about a specific claim. Nothing about your numbers lives in a black box you have to dig through yourself.
Do you work with dermatology practices in every state?
Yes. Our team supports general dermatology, Mohs surgery, and dermatologic surgery practices across all 50 states and works with Medicare, Medicare Advantage, and commercial payers nationwide. Your location does not change how thoroughly we work your claims or how quickly you get paid.
