How we bill in Arizona
DermBilling USA is a dermatology-exclusive medical billing and revenue cycle management company. We code, submit, appeal, and benchmark claims for dermatology, dermatopathology, and Mohs surgery practices across the United States — and nothing else.

Why work with us
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.
What we do
Generalist billers learn dermatology on your claims. We already speak it — every coder, every A/R specialist, every audit.
CPT 17000-series, 11100 biopsies, Mohs 17311+, and modifier 25/59 discipline reviewed by derm-only coders.
Root-cause denial work with payer-specific appeal templates. We rework, we don't write off.
Biologic and phototherapy authorizations tracked to approval before the patient is roomed.
Cosmetic vs. medical splits handled cleanly, with friendly digital statements and payment plans.
Provider-level RVU, payer mix, and per-visit yield dashboards benchmarked against derm peers.
Payer enrollment and revalidation for new derms, PAs, and satellite locations.
Dermatology only — nothing else
Every coder on your account is credentialed in dermatology, dermatopathology, and Mohs. Here is the code territory they live in.
Stage counting, same-day repair bundling, and closure-size documentation checked before submission.
Lesion counts, margins, and benign vs. malignant pathology reconciled against the op note.
Global vs. technical/professional splits, specimen units, and special stain support.
Buy-and-bill units, wastage modifier JW/JZ, and prior auth tracked to approval.
Body-surface-area thresholds and per-session frequency limits mapped payer by payer.
Split-encounter workflows so aesthetic revenue never contaminates a medical claim.
Every E/M paired with a same-day procedure passes a derm-specific documentation test before release.
1,100+ dermatology LCD, NCCI, and commercial edits maintained monthly across all 50 states.

How to check us out
We do not publish anonymous or unverifiable praise.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.
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.
Our free claims audit runs on your own de-identified data, so the numbers you evaluate us on are yours, not a marketing statistic.
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
Send a de-identified sample. In 5 business days you get a line-item leakage report with dollar values.
We work inside your PM/EHR. No data migration, no downtime, typical go-live in 14 days.
Charges coded and submitted within 24 hours, with derm-specific scrubbing before they leave.
Every denial worked within 48 hours. Monthly review call with your named RCM lead.
Compliance & security
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.
A signed Business Associate Agreement is executed with every practice before we touch a single claim, chart note, or remittance file.
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.
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.
Every view, edit, and export of PHI is logged and retained for six years, available to your compliance officer on request.
Background-checked coders and A/R specialists complete HIPAA privacy and security training at hire and annually thereafter.
Clearinghouse, hosting, and communication vendors are BAA-covered and reviewed annually. Subprocessor list available on request.
No ambiguity about who can see what, when. Documentation is provided in writing at each stage so your practice keeps a clean audit trail.
Before engagement
Mutual NDA, BAA execution, and a security questionnaire your compliance officer can file.
During onboarding
Named users provisioned in your PM/EHR with least-privilege roles — we never share logins.
Ongoing operations
Quarterly access reviews, annual risk assessment, and a documented 72-hour incident notification workflow.
At offboarding
Access revoked within 24 hours and a written record-return or secure-destruction certificate issued.

Send a de-identified claims sample. Within five business days you get a line-item leakage report — coding gaps, underpayments, and recoverable aged A/R, in dollars.
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.
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.
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.
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.
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
Yes. Dermatology, dermatopathology, and Mohs surgery exclusively. That focus is why our coders catch staging, biopsy, and modifier issues generalist billers miss.
No. We work directly inside ModMed EMA, Nextech, eClinicalWorks, Athenahealth, AdvancedMD, and most major systems. No migration required.
We separate cosmetic self-pay from medically necessary services at charge entry, so insurers see clean claims and patients get accurate, itemized statements.
Most practices are live in 14 days. We run parallel with your current process for the first two weeks so nothing drops.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
