Encounter type
Encounter type is required. ICD-10-CM coding guidelines differ significantly between inpatient and outpatient settings. For instance, in the outpatient setting, one should only code established diagnoses. In the inpatient setting, one should also include all diagnoses that are uncertain, even those that are ruled out. Use icd10cm-inpatient for inpatient cases and icd10cm-outpatient for outpatient cases. The correct guideline set is applied automatically based on the suffix.
