Spontaneous rupture of flexor tendons, right forearm

This code signifies a non-traumatic tear of a flexor tendon located in the right forearm. This rupture occurs without external force or injury, often due to underlying degenerative changes, inflammatory conditions, or chronic overuse. It typically results in sudden loss of function in the affected digit(s) or wrist.

Apply this code when documentation explicitly states a spontaneous or non-traumatic rupture of a flexor tendon in the right forearm. This is commonly seen in patients with conditions like rheumatoid arthritis, chronic tenosynovitis, or those on certain medications that weaken tendons. Supporting documentation should clearly specify the spontaneous nature of the rupture and its location.

• Ensure the documentation specifies "spontaneous" or "non-traumatic" to differentiate from traumatic ruptures.
• Verify the laterality (right forearm) is clearly documented.
• Do not use this code for ruptures due to acute injury; those would fall under traumatic injury codes.
