Info

Because the internal format of the grouper tables is optimized inD280RT for fast lookups and is therefore difficult to read, the fourprincipal tables included in D280RT are provided as flat EBCDICfiles on the distribution tape. See chapter 2 for table layout details.5.4 Medicare Severity DRG Software Installation Guide 10/10
Construction of the record maskThe following list describes how the executor constructs the recordmasks.1. Sex is tested for validity (1-2).— An error indicator is turned on if sex is out of that range.— If not, the appropriate indicator is set in the record mask.2. Discharge status is tested for validity (01-07, 20, 21, 30, 43, 50,51, 61-66, 70)— An error indicator is turned on if discharge status is out ofrange.— Otherwise, the appropriate indicators are set in the recordmask.3. The first listed diagnosis (assumed principal) is looked up in theDiagnosis Table.— If no entry is found, the record is assigned DRG 999, RTC 7and no further processing occurs.— If an entry is found, but the MDC number is 0, the record isassigned DRG 999, RTC 7 and no further processing occurs.— Otherwise, the MDC and DXCAT are saved and the indicatorsfor this diagnosis code are moved to the mask whereprincipal diagnosis indicators are positioned.4. All secondary diagnoses are looked up in the Diagnosis Tableand their bit indicators “OR’d” together in the mask reserved forsecondary diagnosis indicators. Additionally, if any of the secondariesis a complication or comorbidity, the CC exclusionsubroutine is called to determine if the CC flag in the recordmask should be set. A complete discussion of the CC exclusionsubroutine appears on page 5.7 later in this chapter.Any secondary diagnosis for which there is no DiagnosisTable entry does not cause an error, but is instead ignored.MDC and DXCAT numbers are of no importance for secondaries.5. Once all diagnoses have been processed, the indicators for principaland secondary are “OR’d” together in yet another indicatorsection mask for ALLDX criteria.6. All procedure codes are looked up in Procedure Table and theirbit indicators “OR’d” together in the mask reserved for procedureindicators. As with secondary diagnoses, invalid procedurecodes do not generate errors, but are ignored.10/10The MS-DRG grouper executor 5.5
