How were the PrimaryCancerCondition diagnoses codes determined?
In researching how cancer diagnoses are captured and exchanged, we considered the following assumptions:
Since the FHIR IG only accepts one value set binding to Condition.code, we determined the most comprehensive approach to cover all 3 coding systems (SNOMED-CT, ICD-10-CM, ICD-O-3) was to create one value set containing the relevant primary cancer condition codes from each coding system.
The value set terms further made the following assumptions:
Inclusion of pre-coordinated codes that indicate laterality and gender (e.g.: C50.811 - Malignant neoplasm of overlapping sites of right female breast).
A summary of how to populate PrimaryCancerCondition diagnosis codes is illustrated below and further documented in the mCODE FHIR IG section 188.8.131.52, Representing Cancer Diagnosis.
