Why work with us

Why Dermatology Practices Outsource Billing to a Specialty-Only Partner

A generalist billing company sees a dermatology claim a few times a week. We see nothing else. That difference shows up in the places dermatology revenue actually leaks: Mohs stage sequencing, biopsy add-on units, lesion destruction frequency limits, dermatopathology TC/26 splits, biologic J-code wastage, and the modifier 25 documentation payers now downcode by default.

  • Certified, dermatology-only in-house coders
  • A named account manager who knows your payers
  • Transparent dashboard reporting, updated daily

What we do

Full revenue cycle, built only for skin.

Generalist billers learn dermatology on your claims. We already speak it — every coder, every A/R specialist, every audit.

Dermatology only — nothing else

We don't bill 30 specialties. We bill skin, all day.

Every coder on your account is credentialed in dermatology, dermatopathology, and Mohs. Here is the code territory they live in.

17311–17315 · 14000s · 15000s

Mohs & reconstruction

Stage counting, same-day repair bundling, and closure-size documentation checked before submission.

Nationwide service

DermBilling USA serves dermatology practices across all 50 states.

Every state denies a dermatology claim in its own way: a different Medicare contractor, a different Medicaid plan, a different prompt-pay clock. We bill from a single office at 37 Grand Blvd, Brentwood, NY 11717 and work each market's rules from there. Our dermatology billing locations hub lists the state and metro pages, each with the contractor, Medicaid program and local filing rules that apply there.

How to check us out

We would rather be verified than quoted

We do not publish anonymous or unverifiable praise. Every claim we make about our work is something you can check directly before you switch billing partners.

Speak to a current client

We put you on the phone with a practice administrator running a comparable derm book — same size, same payer mix, same EHR — before you sign anything.

See the audit before you commit

Our free claims audit runs on your own de-identified data, so the numbers you evaluate us on are yours, not a marketing statistic.

Reporting you can verify

Clean claim rate, days in A/R, denial rate by reason code and net collection ratio are reported monthly out of your own PM system, not ours.

How it works

From audit to deposits in under 30 days.

  1. 01

    Free claims audit

    Send a de-identified sample. In 5 business days you get a line-item leakage report with dollar values.

  2. 02

    Zero-disruption onboarding

    We work inside your PM/EHR. No data migration, no downtime, typical go-live in 14 days.

  3. 03

    Clean claims daily

    Charges coded and submitted within 24 hours, with derm-specific scrubbing before they leave.

  4. 04

    Relentless follow-up

    Every denial worked within 48 hours. Monthly review call with your named RCM lead.

Compliance & security

Your PHI is handled like it never left the practice.

Dermatology billing means constant contact with protected health information. Here is exactly how we protect it — and the paperwork we hand your compliance officer on day one.

BAA before any data moves

A signed Business Associate Agreement is executed with every practice before we touch a single claim, chart note, or remittance file.

Encrypted end to end

PHI is encrypted in transit (TLS 1.2+) and at rest (AES-256). No PHI is ever exchanged over email, SMS, or consumer file-sharing tools.

Least-privilege access

Role-based access with MFA on every account. Staff see only the practices they are assigned to, and access is revoked same-day at offboarding.

Full audit logging

Every view, edit, and export of PHI is logged and retained for six years, available to your compliance officer on request.

Trained, screened staff

Background-checked coders and A/R specialists complete HIPAA privacy and security training at hire and annually thereafter.

Vetted subprocessors

Clearinghouse, hosting, and communication vendors are BAA-covered and reviewed annually. Subprocessor list available on request.

The compliance process, step by step

No ambiguity about who can see what, when. Documentation is provided in writing at each stage so your practice keeps a clean audit trail.

  1. 01

    Before engagement

    Mutual NDA, BAA execution, and a security questionnaire your compliance officer can file.

  2. 02

    During onboarding

    Named users provisioned in your PM/EHR with least-privilege roles — we never share logins.

  3. 03

    Ongoing operations

    Quarterly access reviews, annual risk assessment, and a documented 72-hour incident notification workflow.

  4. 04

    At offboarding

    Access revoked within 24 hours and a written record-return or secure-destruction certificate issued.

Request your audit

HIPAA-safe intake. Never submit patient names, dates of birth, or any protected health information in this form. By submitting, you agree we may contact you about dermatology billing services and that your details are handled under our privacy policy. Claims data for an audit is exchanged only after a BAA is executed — see our HIPAA notice.

Where to go next, depending on what you are trying to fix

The site is organised around the five things practices come here for. Each section below is a hub with its own detail pages underneath it.

Billing services

Everything we run for a practice — coding, denials, prior authorization, A/R, credentialing and patient billing — is set out under dermatology billing services, where each service page explains what it covers and how it is measured.

Coding and denials

When a claim comes back, the remittance code is the starting point. Our dermatology denial codes index pairs each CARC with the procedure and modifier that produced it, alongside the modifier and procedure coding references.

Locations

Coverage policy, filing windows and Medicaid rules are local, so our dermatology billing by state and metro pages carry the contractor and payer detail for each market we bill.

Resources

Guides, comparisons, the glossary, current coding updates and the revenue leakage calculator all live in the dermatology billing resources library, written for administrators rather than for search engines.

Questions

Dermatology Billing FAQ

Do you only work with dermatology practices?

Yes. Dermatology, dermatopathology, and Mohs surgery exclusively. That focus is why our coders catch staging, biopsy, and modifier issues generalist billers miss.

Do we have to change our EHR or practice management system?

No. We work directly inside ModMed EMA, Nextech, eClinicalWorks, Athenahealth, AdvancedMD, and most major systems. No migration required.

How do you handle cosmetic versus medical visits?

We separate cosmetic self-pay from medically necessary services at charge entry, so insurers see clean claims and patients get accurate, itemized statements.

How long does onboarding take?

Most practices are live in 14 days. We run parallel with your current process for the first two weeks so nothing drops.

Are you HIPAA compliant?

Yes. We execute a Business Associate Agreement before any PHI is shared, encrypt PHI in transit and at rest, enforce least-privilege role-based access, and keep full audit logs. Our HIPAA notice and security practices are published on this site.

What does dermatology medical billing actually cover?

Charge capture and CPT/ICD-10 coding, claim scrubbing and submission, payer follow-up, denial management and appeals, prior authorization, eligibility verification, patient statements and A/R, credentialing, and reporting — all scoped to dermatology, dermatopathology, and Mohs surgery.

How do you code Mohs surgery correctly?

Mohs is billed with 17311 through 17315 by stage and block count on the same anatomic site, with repair and pathology handled separately where documentation supports it. Stage sequencing and unit counts are the most common source of underpayment we correct.

How do you handle dermatopathology TC and 26 splits?

Where the practice owns the technical component and the professional component is read elsewhere (or vice versa), we split 88304, 88305, 88312 and 88342 with the correct TC or 26 modifier and match it to the payer's global billing rules for the place of service.

Why do our modifier 25 claims keep getting denied or downcoded?

Most payers now apply automated edits to a same-day E/M billed with a minor procedure. The E/M must be separately identifiable in the note, not just present. We review documentation patterns, correct them at the source, and appeal the denials that are payable.

What happens to our aged accounts receivable when we switch?

We work legacy A/R alongside current claims rather than writing it off. Aged balances are triaged by payer, timely-filing window, and recoverability, and reported separately so you can see exactly what came back from the old book.

Do you bill cosmetic and medical dermatology differently?

Yes. Cosmetic services are separated as self-pay at charge entry with clear patient-facing pricing, while medically necessary services go to insurance with supporting diagnosis linkage. Mixed visits are split so neither side contaminates the other.

How do biologics and J-code wastage get billed?

Biologic and injectable claims need the correct J-code units, administration code, and JW or JZ wastage modifier, plus an authorization on file before administration. Missing wastage documentation and expired authorizations are the two failures we see most.

What reporting will we receive?

Monthly clean claim rate, days in A/R, denial rate by reason code, net collection ratio, payer mix, and provider-level productivity — pulled from your own practice management system so the figures are independently verifiable.

What does dermatology billing cost?

We charge a percentage of net collections, tiered by practice size, with no setup fee and no long-term lock-in. Pricing is published on this page.

Where do you provide dermatology billing services?

Across all 50 states and the District of Columbia. Medicare rules vary by MAC jurisdiction and Medicaid rules vary by state, so we maintain state-level payer notes for every location we bill.

Who owns our data if we leave?

You do. All claims, remittance, and patient financial data remain the property of the practice and are exported to you in a usable format on request, including at termination.

Is outsourced dermatology billing cheaper than hiring an in-house biller?

It depends on volume. A percentage of net collections usually lands below the loaded cost of a salaried biller once benefits, payroll tax, clearinghouse fees, coding references, and supervision time are counted — and it removes the coverage gap when that one person is out. Below roughly one provider's worth of volume, in-house can still be the better fit.

How is a dermatology-only biller different from a general multi-specialty billing company?

A generalist codes what the note says. A dermatology-only coder knows that a Mohs stage count, a repair classification, a 17110 unit range, an 88305 TC/26 split, and a modifier 25 pairing each have payer-specific edits that decide whether the claim pays. The difference shows up in denial rate and net collection ratio, not in the invoice.

How do we know if we are losing money on our current billing?

Four numbers tell you quickly: clean claim rate below 95%, days in A/R above 35, denial rate above 8%, and net collection ratio below 96%. If any of those are off, the free claims audit quantifies the gap in dollars against your own last 90 days of remittance data.

What does the free dermatology claims audit include?

We review a sample of your recent claims and remittances, score coding accuracy on surgical and pathology lines, identify denial patterns by reason code, and return a written estimate of recoverable revenue. There is no charge and no obligation to sign.

Is there a long-term contract or termination fee?

No. Our agreements run month to month after the initial onboarding period, with a 30-day notice period and no termination penalty. Data is returned to the practice on exit.

Can you handle credentialing and payer enrollment for new providers?

Yes. We manage CAQH maintenance, initial enrollment, revalidation, and group linkage for Medicare, Medicaid, and commercial plans, and we track effective dates so claims are not billed before a provider is active.
