The short version
- Ten firms ranked, including the EHR-bundled options: ModMed BOOST, EZDerm Billing, and Nextech RCM, which is actually delivered by Nextech’s partner Assembly Health.
- The Auctus Group leads the factor matrix: best-in-class derm depth, AI coding built for this work (ProCode AI), and no software agenda — we work inside the EHR you already own.
- Clarity RCM is the derm-exclusive pick for independent general-derm practices. The boutiques, generalists, and EHR-bundled services each win one lane; match the firm’s daily work to your procedure mix.
The 10 best dermatology billing companies in 2026
One disclosure before the rankings: we run the first company on the list. Every firm that publishes one of these ranks itself first, and honestly, you should discount every “best of” list on sight for exactly that reason. Ours included. What you should not discount is the matrix above. Each factor is checkable, every firm here wins at least one lane, and you can make all of us show our work.
And here is the plain version of why we hold the top spot: every firm below wins one column of that matrix. Clarity wins derm depth, and so do the other focused shops. AnnexMed wins workflow automation. MBC wins price. We are the only company that sweeps every column, and the one that matters most going forward, AI actually coding the claims, has exactly one name in it. And unlike half this list, we are not trying to become your operating system along the way.
1. The Auctus Group: surgical dermatology and the cosmetic crossover
We started Auctus in 2012 with a laptop and seven hundred bucks, and built it on the work where medical and cosmetic coding collide. That is dermatology’s daily tape: Mohs with same-day repairs. Lesion excisions across 11400 to 11646. Modifier 25 on procedure-day E/M, documented well enough that it survives the audit, because eventually there is an audit.
Our depth lives on the line where derm revenue quietly slips away: functional-versus-cosmetic coverage determinations. The excision that is medically necessary in the chart but reads cosmetic to the payer does not get denied loudly. It gets denied quietly, and a biller who does not work that line every day writes it off.
Then the part nobody else on this list has: ProCode AI, our in-house AI coding engine that turns operative reports into CPT, built explicitly for this surgical work and the systems dermatology practices actually run. Plenty of vendors now say “AI” and mean workflow bots running eligibility checks. An engine that does the coding itself is a different animal, and it is ours.
And we are a focused billing service on purpose. We are not building a practice operating system, not bundling an EMR, not boiling the software ocean. Our team and our AI work inside whatever platform you already run, ModMed, Nextech, and EZDerm included, across more than a few dozen EHR and PM systems, so hiring us never means changing software. Credentialing, prior auth, and payer contracting live in-house too, and the free tools are public: our global period calculator gets used every day by billers who will never become clients — as does the wider Billing IQ suite (live Medicare rates, medical-necessity policy links, patient-liability estimates). That is fine with us (mostly).
Best fit: surgical and Mohs-heavy practices and derm practices with cosmetic lines. If you are a small general derm clinic with a simple payer grid, the next firm down may fit you better.
2. Clarity RCM: derm-exclusive at scale
Clarity is the largest dermatology-only billing company in the country by their published figures: roughly 205 practices across 42 states and about $1.46 billion in derm charges a year, with a claimed 98% clean claim rate. Their numbers, not ours. But we compete with them for deals, and inside their lane they are good at what they do.
They spent 2026 turning into a software company. ClarityPay shipped in January for patient payments. ClarityOS, announced at AAD in March, gets called a practice operating system; what it actually is, per their own materials, is a claims-and-dashboards layer on top of their billing service, collections, A/R, payer performance, and patient payments in one view, benchmarked against their practice base. Useful, and not standalone: it exists to make the service harder to leave.
The stated ICP is independent practices. DSO-backed, PE-owned, and hospital-affiliated groups sit outside their model.
Best fit: independent, general-dermatology practices that want a derm-only vendor with scale behind it.
3. Inga Ellzey Practice Group: the coding authority
Inga Ellzey has been the name in dermatology coding education for decades. The Complete Coder for Dermatology reference updates annually and sits on billers’ desks across the specialty, including a few of ours.
The differentiation is coding IP and pedigree rather than technology or scale. No platform story, no automation layer. Deep derm coding expertise, delivered as a service.
Best fit: practices that rank coding authority above everything else and want the firm that wrote the reference material.
4. DermCare Billing Consultants: the derm boutique
Derm-only and high-touch. A dedicated account manager per practice, fee schedule analysis, front desk training, soft collections, and old AR recovery. The service list reads like a practice manager wrote it, which is a compliment.
Best fit: smaller practices that want a named human who knows their account, not a ticket queue.
5. AnnexMed: multi-specialty scale with an AI layer
AnnexMed is a full-cycle multi-specialty RCM firm that launched an AI agent layer in May 2026 across eligibility, prior auth, claim scrubbing, denial prediction, and AR follow-up. Note what is not on that list: the coding itself. Their derm case studies publish hard numbers, 1,700 underpaid dermatology claims recovered in six weeks in one, a 22% clean claim lift in another.
Those are their case studies, so the move is to ask for references from practices your size. Dermatology is one spoke in a wheel that also covers cardiology, orthopedics, radiology, and oncology.
Best fit: larger groups that rank automation and enterprise process above specialty depth.
6. PGM Billing: billing plus software
PGM runs physician and lab billing tracks, sells its own Northstar practice management platform, and keeps an active dermatology blog alongside free tools: an ICD lookup, an ROI calculator. Utility as lead generation works. It is why we publish calculators too.
Best fit: practices that want billing and practice management software from one vendor and can live with multi-specialty depth.
7. Medical Billers and Coders: the volume generalist
MBC repositioned in 2026 as “Total Revenue Integrity”: offshore processing paired with US-based payer negotiation, and denial-prediction claims built on a reported 12.6 million claim patterns. Generally speaking, that model prices below anything derm-specific on this list.
The reciprocal of the price is the depth. Specialty “Centers of Excellence” spread across every vertical mean your Mohs claims are handled by a team that did cardiology yesterday.
Best fit: cost-driven multi-specialty groups where derm is one line among many.
8. ModMed BOOST: billing from your EHR vendor
The last three entries are a different animal: billing bundled with software you may already own. ModMed sells billing services under the BOOST banner, run inside its own ecosystem. If you are on ModMed and want one throat to choke, it is the tidy option.
Two things to weigh. Your billing accountability now lives with your software vendor, so leaving one means re-evaluating the other. And we say this as a firm that bills inside ModMed for clients every day: the platform is good, but that is a separate question from whether its billing arm is the right advocate against payers.
Best fit: ModMed practices that value one-vendor simplicity over independent accountability.
9. EZDerm Billing: the derm EHR’s own billing arm
EZDerm’s billing service is derm-specific by definition, staffed with certified billers, and advertises 98% collections. The constraint is structural: it exists for EZDerm EHR customers.
If you are on EZDerm and happy with it, this is a fair option to price. If you are not, switching EHRs to reach a billing service is the tail wagging the dog.
Best fit: existing EZDerm practices that want billing native to their platform.
10. Nextech RCM: the billing is done by their partner, Assembly Health
Nextech sells RCM, but read the fine print on who does the work: Nextech RCM is delivered by Assembly Health, Nextech’s exclusive RCM partner, a multi-specialty firm spanning more than 40 specialties that works inside Nextech’s practice management platform. Nextech’s own material claims practices lift collections about 10% on average.
The structure is the thing to weigh. Your billing team works for a partner of your software vendor, one remove past the bundled options above. When a payer fight drags into month four, accountability has a longer walk home.
Best fit: Nextech practices that want billing under their existing vendor relationship and are comfortable with the partner arrangement.
Derm-only vs multi-specialty billing companies: the real trade-off
Derm-exclusive firms see the same payer behavior across hundreds of practices. When a Medicare contractor tightens its coverage position on seborrheic keratosis claims or a commercial payer starts bundling Modifier 25 visits, a derm-only shop catches the pattern in week one because it hits fifty clients at once. That pattern recognition is the honest case for exclusivity, and it is a good one.
The ceiling shows up at your procedure mix. A derm-only firm built on in-network E/M, biopsies, and destructions can wobble the moment your book leans surgical or cosmetic-adjacent, and often carries a practice-structure ICP that excludes DSO and PE-backed groups outright.
Multi-specialty generalists fail in the mirror image. Derm becomes one of forty specialties, and the coder touching your 17311 worked oncology this morning. Nothing wrong with that coder. Everything wrong with the model.
The EHR-bundled services split the difference and add a third failure mode: billing accountability routed through your software vendor, or in Nextech’s case, through your software vendor’s partner.
So the axis is not one lane versus many, whatever the sales decks say. It is whether the firm’s daily work matches your book. General derm with a simple payer grid: derm-only scale works. Surgical derm with cosmetic lines: you need functional-versus-cosmetic depth. On an EHR you like: keep it, and hire billing that works inside it. Pick the firm whose Tuesday looks like your Tuesday.
Six questions that expose a weak dermatology billing agency
Run these on every sales call, then get the answers in writing. The vetting call is the product demo. A firm that squirms on pointed questions before you sign will squirm on your denials after, and we have onboarded enough practices out of failed billing relationships to know the squirm always showed up early.
Four numbers frame every one of these conversations: clean claim rate (95% is the floor, and the reciprocal of 95% is a 5% denial rate you fund), days in AR (under 35 on a healthy derm payer grid), net collection rate against your contracts and the CMS Physician Fee Schedule (96% or better), and denial overturn, the number most vendors go quiet on. The quiet is the answer.
- “What is your clean claim rate for dermatology practices my size, and will you put it in writing?” Verbal benchmarks evaporate. Written ones become the standard you manage the firm against.
- “Who works my account day to day, and how many other practices does that person carry?” The answer separates a dedicated team from a shared queue with a dashboard in front of it. For the EHR-bundled options, add: do they work for you, the vendor, or the vendor’s partner?
- “Walk me through your workflow on a Modifier 25 bundling denial.” A derm-literate firm answers in specifics: documentation pull, payer policy citation, appeal timeline. A generalist describes “our appeals process.”
- “Do you run prior auth and credentialing in-house, or does that come back to my front desk?” The gap between “full service” and the contract’s actual scope usually lives here.
- “What happens to my data and my open AR if we separate?” Exit terms matter more as vendors ship proprietary software, and more still when your biller and your EHR are the same company. Ask before you are inside the platform, not after.
- “What percentage of collections do you charge, and what is excluded?” Patient statements, old AR projects, and credentialing are the common add-ons that turn a 5% quote into an 8% invoice.
A good firm answers all six on the first call and confirms in writing without being chased. That behavior, more than any number in the deck, predicts what your billing service relationship will feel like in month nine. It is the same standard we hold our own revenue cycle management engagements to, in writing, from the first call.
Frequently asked questions
What does a dermatology billing company do?
A dermatology billing company manages the revenue cycle for dermatology practices: coding review for visits and procedures, claim submission, payer follow-up, denial management, payment posting, and patient billing. Full-service firms also handle credentialing, payer contracting, and prior authorization. The goal is measurable: raise the clean claim rate and net collection rate, and lower days in AR.
How much do dermatology billing companies charge?
Most dermatology billing companies price as a percentage of monthly collections. Generally speaking, quotes run between 4% and 9%, depending on claim volume, procedure mix, and scope of service. Flat-fee and hybrid models exist, but percentage of collections is the industry default. Always ask what is excluded: patient statements, credentialing, and old AR recovery are common add-ons.
What is the best dermatology billing company in 2026?
The best dermatology billing company is set by your procedure mix and practice structure, so here is the direct answer by segment. For surgical and Mohs-heavy practices or cosmetic crossover, The Auctus Group. For independent general-dermatology practices that want a dermatology-exclusive vendor at scale, Clarity RCM. For small practices that want boutique, high-touch service, DermCare Billing Consultants. For large multi-specialty groups that prioritize automation, AnnexMed.
Should I use my EHR vendor’s billing service, like ModMed BOOST, EZDerm Billing, or Nextech RCM?
EHR-bundled billing services trade independence for convenience. ModMed BOOST and EZDerm Billing are run by the EHR vendors themselves; Nextech RCM is delivered by Assembly Health, Nextech’s exclusive third-party RCM partner. The bundled route works only inside that vendor’s platform and ties your billing accountability to your software contract. An independent, system-agnostic billing company works inside your existing EHR and can be held accountable, or replaced, without touching your software.
Do dermatology billing companies handle prior authorization?
Some do, and the difference matters. A full-service dermatology billing company or dedicated dermatology prior authorization team runs biologic and procedure authorizations in-house, including drugs like Dupixent and Skyrizi that carry heavy documentation requirements. Many billing-only vendors hand prior auth back to the practice front desk. Confirm which model you are buying before you sign.
Do dermatology billing companies handle credentialing?
Full-service firms handle credentialing: payer enrollment, revalidations, and contracting. Standalone dermatology credentialing companies exist, but bundling credentialing with billing closes the most expensive gap in practice operations, which is a new provider seeing patients before payer enrollment finishes. That lag time is largely unbillable.
