Using solely the section code to determine the category seems a bit problematic. Granted Problem Observations in the problems section generally will be "problem-list-item" and Observations from the encounters section generally will be "encounter-diagnosis" - there are plenty of other use cases where a CDA Problem Observation maps to a FHIR Condition (e.g. Indications), and the category should be determined by context.

Moreover; the US Core profile that is being conformed to changes based on whether this is a "US Core Problem/Health Concern" vs a "US Core Encounter Diagnosis"

Suggest more generic guidance around the setting of category than a Concept map (which, incidentally says it maps "from (not specified) to (not specified)")
