L-Code
A Healthcare Common Procedure Coding System (HCPCS) alphanumeric code beginning with the letter L, used to identify and bill prosthetic and orthotic devices to Medicare and other payers.
Full Definition
L-codes are Level II HCPCS codes maintained by CMS that begin with the letter L and are used to classify orthotic and prosthetic devices for insurance billing. Each prosthetic component—from a basic SACH foot to a microprocessor-controlled knee—has a specific L-code that determines reimbursement eligibility and amount. Editors reviewing prosthetic billing documents, letters of medical necessity, and insurance preauthorisation requests must ensure L-codes are reproduced exactly, including the correct number of digits (always four digits after the L). Miskeying a single digit can result in claim denial.
Usage
Usage note: Hyphenate as 'L-code.' Always reproduce codes exactly as four digits following the L (e.g., L5100). Do not confuse with CPT codes, which govern physician procedures rather than device supply.
