Leadership

Built by RCM operators
who specialize in derm.

Most billing vendors serve dozens of specialties and spread their expertise thin. Master Billing was built differently — our entire operation is structured around the billing complexity unique to dermatology practices: Mohs coding, Q-code compliance, SRT reimbursement, and Medicare audit risk.

Our leadership team brings 28+ combined years of dermatology-focused RCM experience. That's why dermatologists trust us with their most complex reimbursement challenges — not just their routine claims.

What We Do For Your Practice

Every service built for
dermatology — not adapted.

Generic billers learn your specialty on your dime. We've already done that work — our entire infrastructure is purpose-built for how dermatology practices bill, document, and get paid.

Revenue Cycle Management

End-to-End Billing Infrastructure

Charge capture through payment posting — every touchpoint optimized. We build payer-specific workflows that eliminate leakage at each stage of the cycle and maintain a 98% clean claim ratio consistently.

Charge Capture Claim Submission ERA Reconciliation Payment Posting Eligibility Verification Credentialing
Denials & AR Recovery

Systematic Recovery of Stranded Revenue

86% of denials are avoidable. We analyze root cause by payer, CPT code, and provider — then close the loop permanently. For aged AR, we have a structured 120+ day recovery protocol with documented follow-up chains.

AR Aging Analysis Root-Cause Workflows Payer-Specific Appeals 120+ Day Recovery AI-Driven Reporting
Audit Defense & Compliance

From Pre-Audit Risk to ALJ Resolution

We conduct pre-audit documentation reviews, manage Safeguard/UPIC responses, and represent practices through ALJ appeals. Audit defense is included in our service model — not an upsell when you need it most.

The Expertise Others Can't Match

Mohs surgery stage coding, Q-code skin substitute LCD compliance, SRT billing, and cosmetic vs. medical service splits — handled correctly, every time. We know which payers are aggressively auditing Q-codes this quarter because we track it quarterly.

Client Outcomes

Two practices. Two problems.
One team.

Our work spans the full revenue picture — from insurance AR and denial management to patient collections. Both are leaking from most dermatology practices right now.

"The outbound calling program alone was a game changer. We never thought to do that systematically."

This 3-location Raleigh dermatology group had growing patient volume across SRT, biopsies, cosmetics, and excision procedures — but patient collections had plateaued at ~$50K/month. Front desk staff had no standardized workflow, no tool to quote patient responsibility under specific plans, and no outbound follow-up process for open balances.

Master Billing deployed a three-pillar system: a custom Patient Responsibility Calculator calibrated to CMS allowables and all major commercial fee schedules; full-day on-site staff training with scripted collection workflows and objection handling; and a systematic weekly outbound calling program targeting all open balances by aging bucket. Within six months, the practice hit a record single month of $81K — more than 60% above baseline — and captured $204K+ in incremental revenue versus the pre-engagement run rate.

For Dermatology Practices

Stop leaving revenue
on the table.

The average dermatology practice loses 12–18% of collectible revenue to preventable denials, coding errors, and aged AR. Tell us about your practice and we'll show you exactly where it's happening — within 5 business days.

Mohs & Q-code coding audit
We review your highest-risk CPT codes for documentation gaps that payers use to deny or claw back payments.
AR aging & denial pattern analysis
We map your top denial categories by payer and CPT code, and quantify the exact dollar amount sitting in each bucket.
Revenue expansion opportunities
We identify reimbursable services — SRT, PDT, excimer laser, patch testing — that fit your patient demographics but may be underutilized.
