HCPCS code L2999: Lower extremity orthoses billing guide
Miscellaneous HCPCS codes trip up orthotic billers more than almost any other category. Because HCPCS code L2999 has no fixed fee schedule rate and demands a narrative description on every claim, it attracts heightened payer scrutiny, prior authorization requirements, and denial rates that specific codes simply don’t face. This reference covers when HCPCS code L2999 […]
HCPCS code G0180: Medicare home health billing guide
Most physicians don’t realize they can bill separately for certifying a patient’s need for home health services. Medicare reimburses that clinical act under HCPCS code G0180, but the claim depends on airtight documentation. Skip a signature on the plan of care or confuse G0180 with G0179, and the claim is denied before review even begins. […]

HCPCS Code G0153: Speech-language pathology billing guide
Claims for G0153 are denied more often than billers expect. The code looks straightforward on paper: speech-language pathology services, home health or hospice, 15 minutes per unit. But in practice, a single missing ICD-10 code or a miscalculated timed unit sends the claim back. For speech therapy practice management teams billing Medicare home health, understanding […]
HCPCS code J3370: Deleted and replaced by J3373 billing guide
If your charge master still lists HCPCS code J3370, it’s out of date. CMS deleted J3370, injection of vancomycin HCl 500 mg, effective June 30, 2025, and replaced it with HCPCS code J3373, billed per 10 mg instead of per 500 mg. That change in unit size is the trap. A 1,000 mg dose that […]
HCPCS Code A4361: Ostomy faceplate billing guide
Official descriptor: Ostomy faceplate, each. HCPCS Code A4361 is a Level II supply code maintained by CMS for use on Medicare Part B DME claims.

HCPCS code J1040: Deleted methylprednisolone acetate 80 mg guide
Most billing rejections tied to methylprednisolone acetate injections trace back to one mistake: submitting a dose-specific code that no longer exists. HCPCS code J1040 (the 80 mg dose) was deleted from the HCPCS Level II code set effective April 1, 2024. At the same time, that off-cycle CMS update also removed J1020 (20 mg) and […]
