LCode Recommendations

In the United States, prosthetists must classify the components of a prosthesis according to standard billing codes, called L-codes. WillowWood, as well as other industry manufacturers, suggests L-codes for their products. It is the responsibility of prosthetists to use correct coding when submitting information to Medicare and private insurance companies.
