How C23GRZZ 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. CSectionNuclear Medicine — What family of procedure this is
  2. 2Body systemWhich system it acts on
  3. 3Root operationThe objective — the verb of the procedure
  4. GBody partThe specific site
  5. RApproachHow the site was reached
  6. ZDeviceWhat was left in place, if anything
  7. ZQualifierA further distinction where one applies
