About 0RNW4ZZ

0RNW4ZZ is the ICD-10-PCS code for a release procedure on the right finger phalangeal joint using a percutaneous endoscopic approach. In ICD-10-PCS, release means freeing a body part from an abnormal physical constraint by cutting or by the use of force.

In plain terms, this corresponds to division of joint capsule, ligament, or cartilage, hand and finger, the ICD-9-CM procedure title it maps to (80.44).

For a different body part, codes include 0RN04ZZ (occipital-cervical joint), 0RN14ZZ (cervical vertebral joint), 0RN34ZZ (cervical vertebral disc), 0RN44ZZ (cervicothoracic vertebral joint), 0RN54ZZ (cervicothoracic vertebral disc), 0RN64ZZ (thoracic vertebral joint) and 22 more.

The same procedure with a different approach is coded 0RNW0ZZ (open), 0RNW3ZZ (percutaneous) and 0RNWXZZ (external).

It is an operating-room procedure in the MS-DRG logic for DRG 513 (Hand or Wrist Procedures, Except Major Thumb or Joint Procedures with CC/MCC), DRG 514 (Hand or Wrist Procedures, Except Major Thumb or Joint Procedures without CC/MCC), DRG 906 (Hand Procedures for Injuries), DRG 957 (Other O.R. Procedures for Multiple Significant Trauma with MCC), DRG 958 (Other O.R. Procedures for Multiple Significant Trauma with CC) and DRG 959 (Other O.R. Procedures for Multiple Significant Trauma without CC/MCC), under the surgical categories “Hand or Wrist Procedures, Except Major Thumb or Joint Procedures”, “Hand Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
