HCPCS code B4159: Enteral formula billing guide for DME suppliers
HCPCS code B4159 is a billable Medicare DMEPOS code for enteral formula for pediatric patients — nutritionally complete, soy based, with intact nutrients — billed at 100 calories per unit.

HCPCS code A4463: Surgical dressing holder, reusable, each
HCPCS code A4463 is the Level II code for a surgical dressing holder, reusable, each. DME suppliers bill it for a device that holds a wound dressing in place, built for repeated cleaning and reuse rather than one-time disposal. It looks like a minor supply code, yet it gets denied constantly. Almost every rejection traces […]

HCPCS code E0140 covers a walker with trunk support, adjustable or fixed height, any type, billed under the Medicare Part B durable medical equipment (DME) benefit.

HCPCS code C1730: Electrophysiology catheter billing guide
HCPCS code C1730 describes a diagnostic electrophysiology catheter with 19 or fewer electrodes, excluding 3D mapping capability.

The distinction […]

HCPCS code A4459: Transanal irrigation system billing guide
HCPCS code A4459 changed in a way most billing sheets still don’t reflect. Since April 1, 2025, the descriptor for the manual transanal irrigation (TAI) system no longer includes the catheter. Bill it alone, the way older guidance said to, and Medicare kicks the claim back. The fix is simple once you know it. A4459 […]
HCPCS Code B4185: Parenteral nutrition solution billing guide
HCPCS Code B4185 is a billable HCPCS Level II code for the lipid component of parenteral nutrition solution, reported per 10 grams of lipids.
