K0740 is a HCPCS Level II code for repair or nonroutine service for oxygen equipment requiring the skill of a technician, labor component, per 15 minutes. It belongs to the Durable Medical Equipment (DME MAC Temporary) section. Medicare does not pay it: see the coverage note below before you bill it.
Medicare coverage: Non-covered by Medicare
Medicare does not cover the item or service this code describes.
From the coverage field of the CMS Alpha-Numeric HCPCS File, release 2026Q4-Oct. This states Medicare’s position on the code, not on your particular claim.
Medically Unlikely Edits: units per day
The most units of K0740 Medicare will pay on one date of service. Bill more on a single line and it is denied. The limit is not the same in every setting, so the row that matters is the one matching the claim you are building.
