HCPCS code A4558: Conductive gel billing and coverage guide
Bill HCPCS code A4558 as its own line on a TENS or NMES claim, and expect a denial. Medicare doesn’t pay for conductive gel separately when it’s used with those devices, no matter how clean the rest of the documentation is. The gel itself is a legitimate, billable supply. It’s just not billed under its […]
HCPCS code A4557: TENS and apnea monitor lead wires guide
HCPCS code A4557 pays for lead wires, the cables that carry the signal from an electrode to a TENS unit or an apnea monitor, billed in pairs. That’s the whole code. The complications start with what billers assume gets billed alongside it. A lot of DME billing guides still describe electrodes and lead wires as […]
HCPCS Code J9070: Cyclophosphamide 100 mg billing guide
HCPCS Code J9070 identifies cyclophosphamide, 100 mg per billed unit, administered under the Medicare Part B buy-and-bill model for physician-supervised chemotherapy infusion. CMS deactivated J9070 effective March 31, 2024, and replaced it with codes J9071–J9075, which price cyclophosphamide per milligram instead of per 100 mg unit. The most common error on legacy J9070 claims was […]
HCPCS Code S9443: Lactation Classes, Non-Physician Provider, Per Session
HCPCS Code S9443 is a Level II alphanumeric code for lactation classes, non-physician provider, per session. It gives IBCLCs and other non-physician lactation providers a billable option for per-session lactation classes, though coverage is payer-dependent, documentation requirements vary, and Medicare does not recognize the code at all. This reference covers everything billing staff and lactation […]
HCPCS Code A9513: Lutetium Lu 177 dotatate billing guide
Most billing errors on HCPCS Code A9513 claims trace back to one of three mistakes: wrong unit count, missing ICD-10 substantiation, or submitting without the required administration CPT code alongside it. Each error can trigger a denial from Medicare or a commercial payer, delaying reimbursement for one of the most expensive drugs in the oncology […]
HCPCS Code V5160: Dispensing fee, binaural
HCPCS Code V5160 is the billing code for the professional dispensing fee when an audiologist or hearing instrument specialist fits hearing aids in both ears during the same encounter. Use it in place of the monaural code (V5241) whenever the fitting covers both ears. This reference covers the official description, billing guidelines, payer coverage, related […]
HCPCS Code Q5101: Zarxio billing, reimbursement, and modifiers
HCPCS Code Q5101 is a Level II code for injection, filgrastim-sndz, a biosimilar, 1 microgram — the code used to bill Zarxio. Most claim denials for this drug trace back to one of three errors: billing J1442 (the reference product) instead of Q5101, omitting the route-of-administration modifier, or submitting with a stale ASP rate after […]
HCPCS Code L0457: Flexible TLSO billing, coverage, and fee schedule
HCPCS code L0457 is the Level II billing code for a flexible thoracic-lumbar-sacral orthosis (TLSO) that’s prefabricated and dispensed off-the-shelf. Most claim denials for this code share one root cause: the brace shipped before documentation was complete. Claims management software that enforces a pre-submission checklist catches missing documentation before CMS adjudication. This reference covers every […]
HCPCS Code J1050: Medroxyprogesterone acetate injection billing guide
HCPCS Code J1050 is billed per 1 mg of medroxyprogesterone acetate, covering both the intramuscular Depo-Provera and subcutaneous Depo-subQ Provera 104 formulations. A standard 150 mg intramuscular dose is billed as 150 units, and the 104 mg subcutaneous dose is billed as 104 units — getting that unit count wrong is the most common cause […]
HCPCS Code E0118: Crutch substitute lower leg platform billing guide
Most guidance on HCPCS Code E0118 assumes it behaves like the rest of the crutch and cane code range: document medical necessity, append the KX modifier, and Medicare pays. That assumption does not hold up against the source policies. Local Coverage Determination L33733 (Canes and Crutches) sets medical necessity criteria for E0100, E0105, and E0110 […]
