Large drop in number of Procedure Occurrence Records

[DTorok (Don Torok)]

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?

[Christian_Reich]

Yeah. That’s correct. We could have a double mapping to Outpatient visit plus some procedure “evaluation and management”. Except the latter one really is not a procedure, but rather something that happens by default all the time. And yes, the total procedure count would go down.

Is there a recommendation for where these records should go? Or do we just accept the drop in procedure records?

Hello @Tom_Galia and all,

Let’s move the CPT4 domain change discussion to this thread. It has more responses and more recent responses.
