I am working on the codes for the peripheral angioplasty - amputation study we discussed the other day. I want to ensure that my use of standard vs non-standard codes is correct.
I am basing my actual selections off CPT codes, which are non-standard. So am I correct that I would use the ‘CPT4-SNOMED eq’ relationship_id in concept_relationship to get the desired SNOMED codes, then build the full concept list by retrieving all descendants of those SNOMED codes using the concept_ancestor table?
I imagine reviewing the SNOMED codes directly might be a better practice, but it is helpful to look at CPT coding recommendations for these procedures put out by various professional organizations.
Thanks,
Jon
