What This Code Means

A tendon in the right shoulder that normally straightens or extends the arm has spontaneously torn or ruptured without an obvious injury.

Coding Tips

  • •Verify the rupture is spontaneous (not traumatic) and involves extensor tendons specifically
  • •Confirm right shoulder laterality is documented in the medical record
