Is L0120 covered by Medicare?

Coverage varies by code, payer, and clinical context. Cross-check the current Medicare Local Coverage Determination (LCD) for the adjudicating Medicare Administrative Contractor (MAC), and any commercial payer policy for non-Medicare patients. Many HCPCS Level II codes (especially DME and certain drugs) require prior authorization.

What documentation is required for L0120?

Documentation must support medical necessity per the payer LCD or commercial-payer policy. For DME codes: written order, face-to-face encounter where required, beneficiary education. For drug codes: NDC, dose administered, units, route, site, wastage if applicable. For ambulance: origin, destination, miles, medical necessity. For supplies: linked diagnosis and medical necessity.

What are common denial reasons for L0120?

The most common denial categories are CO-16 (information missing or incorrect), CO-50 (medical necessity), and CO-151 (benefit maximum reached, often for DME rental cycles). Specific denial behavior varies by payer and plan.
