Payment of Drugs, Biologicals, and Supplies in a CORF

100.7 - Payment of Drugs, Biologicals, and Supplies in a CORF (Rev. 1459; Issued: 02-22-08; Effective: 07-01-08; Implementation: 07-07-08) Drugs Drugs and biologicals generally do not apply in a CORF setting. Therefore, contractors are to advise their CORFs not to bill for them. Supplies The CORFs should not bill for the supplies they furnish when such supplies are part of the practice expense for that service. Under the MPFS, nearly all of these expenses are already taken into account in the practice expense relative values. However, CORFs may bill separately for certain splint and cast supplies, represented by HCPCS codes Q4001 through Q4051, when furnishing a cast/strapping application service in the CPT code series 29000 through 29750. Vaccines The CORFs should refer to Chapter 18, Preventive and Screening Services, for billing guidance on influenza, pneumococcal pneumonia, and Hepatitis B vaccines and their administration.
