A code indicating the conflict, intervention and outcome of a prescription presented for fulfillment. The T-MSIS Drug Utilization Code data element is composite field comprised of three distinct NCPDP data elements: "Reason for Service Code" (439-E4); "Professional Service Code" (440-E5); and "Result of Service Code" (441-E6). All 3 of these NCPDP fields are situationally required and independent of one another. Pharmacists may report none, one, two or all three. NCPDP situational rules call for one or more of these values in situations where the field(s) could result in different coverage, pricing, patient financial responsibility, drug utilization review outcome, or if the information affects payment for, or documentation of, professional pharmacy service. The NCPDP "Reasons of Service Code" (bytes 1 & 2 of the T-MSIS DRUG-UTILIZATION-CODE) explains whether the pharmacist filled the prescription, filled part of the prescription, etc. The NCPDP "Professional Service Code" (bytes 3 & 4 of the T-MSIS Drug Utilization Code) describes what the pharmacist did for the patient. The NCPDP "Result of Service Code" (bytes 5 & 6 of the T-MSIS Drug Utilization Code) describes the action the pharmacist took in response to a conflict or the result of a pharmacist's professional service. Because the T-MSIS Drug Utilization Code data element is a composite field, it is necessary for the state to populate all six bytes if any of the three NCPDP fields has a value. In such situations, use 'spaces' as placeholders for not applicable codes.
