Question: When should providers bill for orthotics (code ex: L3000)? Some people say at casting and others say at dispensing, so I cannot get a clear answer. Maine Subscriber Answer: Providers should bill for orthotics at dispensing. Dispensing is considered the service date. If something happens to the patient, and the orthotics, for example L3000 (Foot, insert, removable, molded to patient model, ‘UCB’ type, Berkeley Shell, each), are never dispensed, then there is no refund that has to be made to the insurance company.
