How 4A0174Z is built

Every ICD-10-PCS code is seven independent character positions. Each one is a separate decision, and the meaning of a character depends on the positions before it.

  1. 4SectionMeasurement and Monitoring — What family of procedure this is
  2. ABody systemWhich system it acts on
  3. 0Root operationThe objective — the verb of the procedure
  4. 1Body partThe specific site
  5. 7ApproachHow the site was reached
  6. 4DeviceWhat was left in place, if anything
  7. ZQualifierA further distinction where one applies
