Orthotics Billing: Protecting Your Margins

Fee Schedule Strategy

Many practices undercharge or overcharge when billing for orthotics. Both mistakes cost money—either in lost revenue or triggering payer audits.

  • Medicare Fee Schedule as a Baseline: We use your Medicare Administrative Contractor (MAC) as the benchmark for L-code pricing.
  • Smart Overcharging: Charging 120–130% of Medicare ensures consistency across payers without raising red flags.
  • Secondary Payer Advantage: Overcharging slightly allows secondary insurance to pay its portion correctly.

Example: For L3000 orthotic inserts, we recommend pricing around $490 per unit, balancing compliance with profitability.

Tools We Leverage

  • Fair Health (fairhealthconsumer.org) to benchmark ZIP-code specific reimbursements.
  • Encoder Pro for integrating Medicare + Fair Health data in one place.
  • Supplier Pricing Data to make sure every billed device is profitable.
Our Approach: We bill DME directly for providers rather than you referring them to dispensing suppliers, so your practice captures maximum reimbursement.

Skin Graft Billing: Turning Complexity into Compliance

Billing skin grafts is especially tricky because they’re billed with Q-codes and require exact alignment with National Drug Codes (NDCs).

How We Get It Right

  • NDC Crosswalk + ASP Pricing: We pull from CMS files to match graft size with the correct billable units and payment limits.
  • Product-Specific Pricing: The same graft (e.g., PuraPly AM) can have very different NDCs and units. We calculate the exact reimbursement before the claim goes out.
  • Commercial Plans: We price 120–150% of Medicare’s ASP limit to maximize commercial reimbursements.

Compliance Safeguards

  • Chart notes must match graft size and units.
  • NDC codes are always included on claims.
  • PM/EMR macros connect graft codes to NDCs, saving your staff hours of manual entry.

Working with Suppliers: Avoiding Pitfalls

Not all suppliers are created equal. The wrong supplier leaves you with unpaid invoices and no billing support.

  • What we expect: Clear billing guidance, coding assistance, and appeal support.
  • What to avoid: “Invoice-only” suppliers who abandon you after the sale.
Our Approach: At Bonfire Revenue, we vet suppliers and align them with billing practices that actually get reimbursed.

Wound Care: Beyond Orthotics and Grafts

  • Dressings: Quantity modifiers (A1–A9) add incremental revenue that builds up over time.
  • Debridement: Proper depth coding (skin vs. fascia vs. bone) is the difference between a denial and a full payment.
  • Add-on Codes: We bundle correctly to avoid compliance risks.

Medicare Part B vs. DME MAC: The Credentialing Divide

One of the most common mistakes is billing the wrong Medicare entity.

  • Medicare Part B MAC: Handles professional services and wound care.
  • DME MAC: Handles orthotics and DME items. Requires enrollment via the 855S application and potentially a separate NPI for each location.
Our Credentialing Edge: Bonfire Revenue manages DME MAC enrollment and ensures your PM/EMR systems are mapped to the correct payer IDs—avoiding costly delays.

Modifiers & Compliance: The Fine Print That Pays

We ensure every claim carries the right modifier the first time.

  • NU Modifier: Required by many commercial plans for orthotics.
  • LT/RT Modifiers: Splitting charges by side ensures maximum reimbursement.
  • 50 Modifier: Used for bilateral procedures but applied differently depending on payer rules.
  • GY Modifier: Enables Medicare Part B denials to auto-route to secondary coverage.
