BY31ZZZ — Magnetic Resonance Imaging (MRI) of Fetal Heart

Billable / specific codeICD-10-PCS

CMS abbreviated title: Magnetic Resonance Imaging (MRI) of Fetal Heart

How BY31ZZZ 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. BSectionImaging — What family of procedure this is
  2. YBody systemWhich system it acts on
  3. 3Root operationThe objective — the verb of the procedure
  4. 1Body partThe specific site
  5. ZApproachHow the site was reached
  6. ZDeviceWhat was left in place, if anything
  7. ZQualifierA further distinction where one applies
