Existing Wording: Current Diagnosis Role value set elements:

> Admission diagnosis

> Discharge diagnosis

> Chief complaint

> Comorbidity diagnosis

> Pre-op diagnosis

> Post-op diagnosis

> Billing

Cardinality: 0..1

Proposed Wording: Cardinality should be 0..*. These can overlap. E.g., a diagnosis may be both a discharge and billing diagnosis.

Clarify what a "comorbidity diagnosis" is. Since a diagnosis is almost by definition a comorbidity, this seems redundant.

Add in elements needed for quality measures such as for HEDIS, CMS: Present-on-admission diagnosis, and as subset of billing - facility billing diagnosis, professional billing diagnosis. Rename billing to billing diagnosis.

Comment:

Need to relax cardinality at the base resource level
