Is it ever appropriate to use an ICD10CM code outside the US? I have some ex-US datasets and I’m getting a few hits in ICD10CM that are not in ICD10. I’m assuming I should just stick to ICD10 in ex-US DBs - but figured I’d ask.
Some examples: D47.4 - Osteomyelofibrosis O14.2 - HELLP syndrome Z41.8 - Encounter for other procedures for purposes other than remedying health state
Not sure I understand your question. ICD-10 is fully enclosed in ICD-10-CM. So, all those codes exist in both. But there are a lot of ICD-10-CM codes that don’t exist in ICD-10. Plus, since ICD-10-CM specifies the diagnoses, all those “Other” and “Not otherwise specified” concepts have a slightly different meaning.
But there are other country-specific ICD-10 codes. Germany has ICD-10-GM, for example.
