Do not know when vocab changed, but CPT4 codes for ‘Office or other outpatient visit for the evaluation and management’ now map to standard concepts in the Visit domain. Within a Claims database we convert this will result in at least a 17% drop in the number of Procedure Occurrence records. Have others seen this?
Also, how has this changed your ETL process. If the only event for a visit is recorded as ‘Office or other outpatient visit for the evaluation and management’ then that would result in a visit that does not have any rows in procedure_occurrence, measurement, condition_occurrence… Is the end result to just ignore records with CPT4 codes that map to the visit domain?
