We have only evaluated this implementation on data from a limited set of specialties. This may not generalize to all hospitals. Contact us to share feedback or report issues. Encounter type
Encounter type is required. ICD-10-GM 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 icd10gm-inpatient for inpatient cases and icd10gm-outpatient for outpatient cases. The correct guideline set is applied automatically based on the suffix.
Inpatient procedures
For German inpatient episodes, ICD-10-GM is paired with OPS for procedure coding. Use icd10gm-inpatient for diagnoses and ops for procedures in the same request.
