How 4A01X4Z 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. XApproachHow the site was reached
