Built exclusively for dermatology

Every Feature Your Front Desk Needs

Generic medical billing tools are built for the average practice across all specialties. Dermatology isn't average. Mohs surgery add-on codes, high-volume destruction sessions, MPPR across biopsy combinations, and the NSA's Good Faith Estimate requirements — these are dermatology-specific challenges that require dermatology-specific software. Every feature below was designed for the derm front desk, not adapted from a general-purpose tool.

Compliance

Good Faith Estimate Generator

The No Surprises Act requires providers to give a Good Faith Estimate to self-pay and underinsured patients who request one for scheduled services. The document must include specific provider information, itemized expected charges, and federally mandated language informing patients of their dispute rights. DermEstimator's GFE generator produces a fully compliant document in one click.

The GFE is generated directly from the completed estimate — procedure codes, allowed amounts, and patient cost-share figures are all pre-populated. The required federal disclosure language is locked into the template and cannot be edited, preventing inadvertent compliance gaps. Your practice's name, NPI, and address are pulled from your account settings.

Every generated GFE is stored in the estimate history alongside the underlying estimate, providing a complete paper trail. If a patient exercises their dispute rights, you have the original GFE on file — dated, timestamped, and tied to the specific procedures that were estimated.

Code Library

525+ Dermatology CPT Codes

The code library is built from the 2026 Medicare Physician Fee Schedule and covers every CPT code a dermatology practice routinely encounters. Biopsies (11102–11107), excisions by site and size (11400–11646), destructions (17000–17286), Mohs surgery (17311–17315), phototherapy, cosmetic injectables, E&M office visits, and procedure-specific add-on codes are all included and updated annually.

The code search is fast and forgiving — type a partial procedure name ("shave", "excision malignant", "mohs") or a CPT code number and relevant results appear immediately. Each result shows the full AMA descriptor so staff can confirm the right code before adding it.

Codes are also browsable by category: Office Visits, Biopsies & Shave Removals, Excisions — Benign, Excisions — Malignant, Mohs Surgery, Destruction, Phototherapy, Cosmetic, and Other. Practices that operate with consistent procedure sets can use the category view to build estimates without memorizing codes.

Billing Rules

Multiple Procedure Rule (MPPR)

Under Medicare's multiple procedure rule, when a physician performs more than one procedure in a single session, the second and subsequent procedures are reimbursed at 50% of their otherwise-applicable allowed amount. This rule applies to the majority of dermatology procedure codes and has significant impact on accurate patient cost estimation — a patient having two excisions will not owe twice the single-procedure amount.

DermEstimator applies MPPR automatically as procedures are added to an estimate. The highest-value procedure is always ranked first (100%), and all additional procedures with MPPR applicability are ranked at 50%. The line-item breakdown in the estimate clearly shows each code's pre- and post-reduction allowed amount, so patients and staff can see the calculation.

Critically, add-on codes that are exempt from MPPR reduction are handled correctly. Mohs surgery add-on codes 17312 and 17314 — which represent additional tissue stages and are always billed in conjunction with a primary Mohs code — are not subject to the 50% reduction. DermEstimator's MPPR logic correctly identifies these codes and applies full reimbursement, matching how Medicare actually pays claims.

Medicare Rates

All 109 Medicare Localities

Medicare does not pay the same rate for the same procedure in every part of the country. The Geographic Practice Cost Index (GPCI) adjusts work, practice expense, and malpractice RVUs based on local cost factors — resulting in meaningful rate differences between localities. A shave biopsy (11305) that pays $68 in a rural Midwest locality may pay $92 in San Francisco.

DermEstimator includes the GPCI-adjusted allowed amounts for all 109 Medicare payment localities as defined in the 2026 MPFS. During account setup, your practice's ZIP code is used to identify the correct locality automatically. Multi-location practices can configure different localities per location.

Using national average rates — as many generic tools do — introduces systematic error for practices in high- or low-cost areas. For a practice in Manhattan, using national averages understates Medicare allowables and understates patient responsibility. For a rural practice, it overstates both. Locality-accurate rates are a baseline requirement for useful estimates.

Insurance

Per-Payer Contracted Rates

Commercial insurance plans don't pay Medicare rates — they pay negotiated contracted rates, typically expressed as a percentage of the Medicare Fee Schedule. A plan might contract at 115% of Medicare for most procedures, or at 90% — the percentage varies by payer and sometimes by procedure category.

Each payer in DermEstimator can be configured with a contracted rate percentage. When a staff member selects that payer for an estimate, all procedure allowed amounts are automatically multiplied by the configured percentage. No manual math, no remembering which plan pays what.

Payer configurations are account-level settings — set them once, and every staff member's estimates use the same rates. Updates to contracted rates after renegotiation take effect immediately across all future estimates.

Custom Data

Custom CSV Fee Schedules

Some payers — particularly regional carriers, Medicaid managed care plans, or specialty networks — have flat-dollar fee schedules rather than percentage-of-Medicare contracts. For these plans, a percentage multiplier won't produce accurate estimates.

DermEstimator supports uploading a CSV-formatted fee schedule directly. Map the CPT code column and the allowed amount column, and the system loads the flat-dollar rates for that payer. Once uploaded, estimates for that payer use the actual contracted amounts rather than a derived percentage.

Custom fee schedules can be updated whenever your contract changes — simply re-upload the updated CSV. The prior schedule is archived, so old estimates remain accurate to the rates that were in effect when they were created.

Cost-Share Logic

Deductible & Co-insurance Tracking

The correct cost-share calculation follows a specific sequence: the patient's remaining deductible is applied first, reducing the allowed amount. Co-insurance is then calculated only on the amount that exceeds the deductible. This distinction matters significantly when a patient has a partial deductible remaining — a patient with $200 remaining on a $1,500 deductible who has a $350 procedure owes $200 deductible plus 20% of the remaining $150, not 20% of the full $350.

DermEstimator enforces this logic for every estimate. Enter the patient's remaining deductible and co-insurance percentage (or copay amount), and the calculation is applied correctly. The line-item breakdown shows the deductible portion and co-insurance portion separately, so the math is transparent to both staff and patient.

Out-of-pocket maximum tracking is also supported — if the patient has met or nearly met their OOP maximum, co-insurance obligations can be zero or reduced. DermEstimator accounts for this when a remaining OOP figure is entered, preventing overestimates that frustrate patients at checkout.

Audit Trail

Saved Estimate History

Every estimate created in DermEstimator is saved automatically with a timestamp, the user who created it, the payer selected, all procedure codes and amounts, and the final patient responsibility figure. This record is permanent and immutable — it reflects exactly what was communicated to the patient at the time.

The estimate history is searchable and filterable by date range, payer, and user. Practices can pull a history of all estimates generated for audit purposes, track which staff members are generating estimates, and review the accuracy of past estimates against actual claims.

When a patient disputes a quote, the estimate history provides an immediate answer: here is what was quoted, on this date, by this staff member, for these procedures. No digging through printed sheets or reconstructing from memory.

Branding

Custom Practice Logo & Branding

Estimates and Good Faith Estimates shown to patients display your practice's logo and name, not DermEstimator branding. Upload your practice's logo in account settings and it appears on all patient-facing documents. The estimate layout is clean and professional — designed to reinforce your practice's identity at every patient touchpoint.

Custom branding applies to on-screen estimates, printed estimate summaries, and generated GFE documents. Patients see your practice name and logo throughout the estimate interaction, not a third-party software tool.

Security

Single-Session Security

Each DermEstimator user account supports one active session at a time. If a staff member's credentials are used to log in from a second device or browser, the first session is immediately terminated. This design prevents shared-login scenarios where multiple staff use the same credentials, which obscures the audit trail and creates security exposure.

Practices with HIPAA security program requirements will note that single-session enforcement is a straightforward access control measure — one user credential maps to one active session, supporting both audit logging and least-privilege access principles.
