Spontaneous rupture of extensor tendons, unsp upper arm

This code signifies a non-traumatic tear of the extensor tendons in an unspecified upper arm. This rupture occurs without an external force or injury, often due to underlying degenerative changes or inflammatory processes within the tendon. It results in impaired extension function of the affected arm.

Use this code when documentation clearly indicates a spontaneous (non-traumatic) rupture of an extensor tendon in the upper arm, and the specific arm (right or left) is not specified. This typically applies when a patient presents with sudden onset of pain and loss of extensor function without a reported injury event.

• Ensure documentation specifies "spontaneous" or "non-traumatic" to differentiate from traumatic ruptures.
• Avoid using this code if the laterality (right or left upper arm) is documented; instead, choose a more specific code.
• Consider additional codes for underlying conditions contributing to the spontaneous rupture, such as rheumatoid arthritis or chronic tendinopathy.
