Duplicate OPCS4 Codes Per Visit

Hi All,

I have a question around multiple procedures during an Outpatient visit at an NHS provider.

Where multiple OPCS4 procedures are coded for a patient during a single outpatient visit how should these be reflected in the CDM where the OCPS4 codes appear multiple times?

For example:
Patient X has the following coded procedures - procedures coded in order of occurrence:

coding position OPCS4 Procedure Descp
1 U13.4 x-ray joint plain
2 W92.5 Examination of Joint
3 Z85.6 ankle joint
4 W92.5 Examination of Joint
5 Z86.9 Other joint of foot nec
6 X62.1 assessment by uniprofessional team nec

As you can see in this example, the patient has had diagnostics on 2 body parts (ankle joint and other joint of foot), so we see a W92.5 (Examination of Joint) coded once for the ankle and once for the ‘other joint of foot’.

How should the above example be reflected in the CDM?

Many thanks
Helen
