A tendon in the right upper arm 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 of the upper arm
  • •Confirm right upper arm laterality is documented in the medical record
