The short version
- Payer credentialing runs 90 to 120 days before a new dermatology practice can bill anything in-network. A biller hired at open is a fixed salary watching that queue.
- Outsourced billing at 4 to 9 percent of collections is the only billing cost that matches a startup’s revenue ramp: near zero while collections are near zero, real money only once revenue is real.
- The setup order: credentialing first, fee schedule built from your actual contracts, eligibility and prior auth at the front desk, billing partner live before the first patient.

Payer credentialing for a new dermatology practice runs 90 to 120 days
Credentialing and contracting run 90 to 120 days from application to effective date, and Medicare enrollment runs on its own clock inside that window. Until the contracts are effective there is no payer grid, and no payer grid means no in-network claims. Every visit before the effective date gets paid out of network, late, or never.
Now run that against the standard startup hiring plan. A biller hired at open is $5,000 to $6,000 a month, fully loaded, watching a credentialing queue — the claims she was hired to work do not exist yet. She will spend her first quarter building a filing system for them.
Generally speaking, the practices that get this right start credentialing the day the legal entity exists. Before the lease, before the EMR demo, before the logo. Every week the applications wait is a week of care at open you deliver out of network or free, so the applications go first — the rest of the billing setup can run in parallel, and this one thing cannot.
| Hire a biller at open | Outsource from day one | |
|---|---|---|
| Cost during credentialing | $5-6K a month with no claims to work | A percentage of near-zero collections |
| When volume ramps | One person absorbs it, or doesn’t | Absorbed by the team; no second hire |
| Payer-grid knowledge | Whatever the hire brings with her | Specialty team; edits tracked across clients |
| Credentialing | Usually not her job | Included or bundled — confirm scope in writing |
| Day-one claims | Learning your setup while claims wait | Live before the first patient |
| Accountability | A performance review | A contract with numbers in it |
What billing costs a new dermatology practice: the salary versus the percentage
BLS puts the median billing and posting clerk at $48,500 a year in its May 2025 survey, and a dermatology-literate biller in a competitive market prices in the $50,000s before a single benefit dollar. Add 25 to 30 percent for payroll taxes, coverage, and PTO, then the PM seat, clearinghouse fees, and statement costs, and a solo billing operation runs $70,000 to $80,000 a year fully loaded. It runs that number whether claims go out the door or not.
A startup’s first quarter is the “or not.” Collections ramp from zero while the payer grid comes online, which means the fixed-cost model bills you hardest during exactly the months you collect least.
Outsourced dermatology billing prices at 4 to 9 percent of monthly collections. Four to 9 percent of near-zero is near zero — the fee ramps only as revenue does, and that is the only billing cost structure that matches a startup’s cash curve. The table above is the whole argument in six rows: at open you are not choosing between a person and a service. You are choosing between a fixed cost and a variable one, and only one of them knows your revenue starts at zero.
How to set up billing for a new dermatology practice: the day-one sequence
Number one: credentialing and contracting, immediately, per the clock above. Number two: build the fee schedule and payer grid from your actual executed contracts — not the Medicare percentages a consultant pasted in from the last practice she launched. The gap between those two documents is where underpayments hide for years.
Number three: eligibility checks and prior auth workflow at the front desk before the first patient is on the schedule. Dermatology denials are born at check-in, not in the billing office — biologics prior auth, cosmetic-versus-medical determinations, and the modifier 25 visits payers love to challenge all start as front-desk questions. Number four: billing partner live before the first patient, so day-one claims go out on day two.
We ranked the firms that do this work, ours included, in our dermatology billing company rankings, and the vetting questions there apply doubly to a startup. You are buying a payer-grid education, not claim submission.
Choosing a dermatology billing company when you have no billing history
An established practice vets a billing company against its own history — days in AR before and after, denial rate before and after. A new practice has no before. The substitute is a contract with performance numbers in it: clean claim rate at 95 percent or better, days in AR under 40 once the ramp settles, net collection rate at 96 percent or better against your contracts and the CMS fee schedule, denial overturn reported monthly.
The reciprocal of a 95 percent clean claim rate is a 5 percent denial rate, and whose queue those denials sit in is the entire difference between vendors. Ask what is excluded before comparing quotes: patient statements, credentialing, prior auth, and monthly minimums during the ramp are the add-ons that move an advertised 4 percent to an effective 7. A firm that resists writing its numbers down has answered your real question early.
One more carve. If you are reading this with an in-house biller already on payroll, you are a different article — the fully loaded math for an established practice is in our in-house versus outsourced dermatology billing comparison. This one is for the practice that still gets to choose its first fixed cost. Choose fewer.
And while you are deciding, use the free stuff: our Resource Center keeps practice-manager guides, payer references, and a searchable billing FAQ open to everyone — client or not.
Frequently asked questions
How do I outsource billing for a new dermatology practice?
Start before the practice opens: payer credentialing and contracting run 90 to 120 days, so engage a billing partner that handles enrollment first. Build the fee schedule and payer grid from your actual contracts, set up eligibility and prior authorization at the front desk, and have the billing service live before the first patient visit. A percentage-of-collections fee matches a new practice’s revenue ramp, so you avoid paying a fixed billing salary during the months credentialing keeps revenue at zero.
When should a new dermatology practice start credentialing?
As soon as the legal entity and tax ID exist, and before the office lease if possible. Payer credentialing and contracting run 90 to 120 days from application to effective date, with Medicare enrollment on its own timeline, and visits before the effective date are generally paid out of network or not at all. Starting applications four months before opening is the highest-leverage billing decision a new practice makes.
How much does outsourced medical billing cost for a new practice?
Most dermatology billing companies charge 4 to 9 percent of monthly collections, so the fee scales with a new practice’s revenue ramp — small while collections build, real money only once revenue is real. Ask about monthly minimums, setup fees, and whether credentialing is bundled or billed separately, because those are the costs that arrive before the percentage means anything.
Should a new dermatology practice hire a biller or outsource billing?
Generally speaking, a new dermatology practice should outsource at open: credentialing keeps revenue near zero for 90 to 120 days, and a percentage-of-collections fee is near zero in those months while a hired biller is a fixed salary with no claims to work. In-house billing becomes defensible later, once claim volume can keep two or more billers busy and a single resignation no longer ages the practice’s AR.
What does a dermatology billing service include?
A full-service dermatology billing company handles coding review, claim submission, payment posting, denial management and appeals, payer follow-up, patient billing, and monthly reporting on clean claim rate, days in AR, and net collection rate. Many also provide credentialing, payer contracting, prior authorization, and old AR recovery, though these are often priced separately. Confirm scope line by line, because the gap between full service and the contract is where front-desk work quietly returns to your staff.
Do dermatology billing companies handle credentialing and payer contracting?
Most full-service dermatology billing companies handle credentialing and payer contracting, though many price it separately from the percentage-of-collections fee. For a new practice this is the piece to confirm first: credentialing has to start 90 to 120 days before opening, and the partner who builds your payer grid from those contracts is better positioned to bill against it correctly. Get enrollment scope and pricing in writing before signing.
This article describes how billing arrangements, credentialing timelines, and vendor pricing generally work — it is not legal, tax, or financial advice. Credentialing clocks, contract terms, fee structures, and what counts as “collections” vary by payer, state, and vendor. Wage figures cited are national BLS medians and will differ in your market. Confirm the specifics with your own counsel and with the vendors you are evaluating before you sign anything.
