 === Proposal ===
-^Field^Required^Type^Description^
+This proposal does not involve a change to the CDM schema.
+This is follow up on discussion at Bethesda F2F meeting. It was suggested to do an evaluation of granularity in various procedural terminologies.
-----
+In the long run (not possible today): The idea is to make all CPT4 codes non standard concepts. (change in OHDSI Vocabulary)
-=== Use Cases ===
+=== Background ===
+A phenotype definition (patient cohort) may include Diagnostic or Medication Code. However, it can also include Procedural code. e.g., patients who had chest X ray done.
+Whereas OHDSI is using SNOMED for Diagnoses and LOINC for lab, there is no "international" terminology for procedures.
+Some Asian countries mapped their procedure codes to CPT4. However CPT4 requires a license. For new data partners within OHDSI, the license requirement may be troubling.
+Possible terminologies may be ICD10PCS or SNOMED (specifically, procedure codes within SNOMED). Snomed does not offer the needed granularity.
+----
+=== Use Cases ===
+Allow procedures to be part of phenotype definitions.
