Coding Guidelines, Compliance, and Practice Management

HCPCS Level II codes are alphanumeric: one leading letter followed by four digits. The lettered ranges identify categories of items/services CPT does not adequately cover (drugs, DME, supplies, transport, temporary codes, etc.).

Items and services such as drugs/biologicals, durable medical equipment (DME), supplies, orthotics/prosthetics, ambulance/transport, and various temporary services that the AMA's CPT code set does not adequately describe.

J codes are used for drugs and biologicals (typically those administered other than by the oral route). Each J code defines a specific drug and a dosage unit.

E codes = durable medical equipment (DME); L codes = orthotics and prosthetics; A codes = ambulance/transport and certain medical/surgical supplies.

Report both the administration code (by route/age/counseling) AND the vaccine/toxoid product code separately. The product code alone does not capture the act of giving it, and vice versa.

Determine units from the documented dose divided by the dosage amount stated in the code descriptor, then round per payer rules. Report the calculated units alongside the appropriate administration CPT code.
