HCPCS Code A4602: Replacement battery for external infusion pump
HCPCS Code A4602 is a HCPCS Level II DME supply code for a replacement lithium 1.5-volt battery, billed only when the patient owns the external infusion pump outright.

HCPCS code J2505: Deleted in 2022, now bills as J2506
If you’re still billing HCPCS code J2505 for pegfilgrastim (Neulasta) in 2026, stop. The code doesn’t exist anymore. CMS deleted J2505 effective December 31, 2021, and replaced it with J2506, which bills at a different unit size entirely. That change alone has caused a wave of denied claims. Practices that carry their old J2505 logic […]
HCPCS code A4250: Urine reagent strips billing guide
Bill HCPCS code A4250 to Medicare, and the claim comes back denied, every time. The code is for urine test or reagent strips, and Medicare treats them as non-covered. They are not underpaid or capped, they are excluded from the DMEPOS benefit entirely. The mix-up is easy to make. A4250 sits in the same code […]
HCPCS Code L8680: Implantable neurostimulator electrode billing guide

HCPCS Code L3906: Wrist hand orthosis, custom fabricated billing guide
Orthotic claim denials rarely come from picking the wrong code family. They come from getting the details wrong inside the right family.

Bill L3906 for a prefabricated orthosis or forget the KX […]
