                The use of NA indicates that the HCPCS code was Not Available. NA may mean that a) the HCPCS code has
                not yet been created (new drug), b) the drug is given as an oral drug or alternative route (only in
                specific instances are HCPCS assigned to these medications), or c) the HCPCS could not be found or is
                truly not available.
