Spontaneous rupture of flexor tendons, unspecified upper arm
ICD-10 M66.329 is a billable code used to indicate a diagnosis of spontaneous rupture of flexor tendons, unspecified upper arm.
Spontaneous rupture of flexor tendons in the upper arm is a condition characterized by the unexpected tearing of the flexor tendons, which are responsible for bending the fingers and wrist. This injury can occur without any apparent trauma or overuse, often linked to underlying conditions such as tenosynovitis, which is inflammation of the tendon sheath. The rupture may lead to significant functional impairment, pain, and swelling in the affected area. Patients may present with an inability to flex the fingers or wrist, and diagnostic imaging such as ultrasound or MRI may be utilized to confirm the diagnosis. Treatment typically involves surgical intervention to repair the ruptured tendon, followed by rehabilitation to restore function. The condition is more prevalent in individuals with pre-existing inflammatory conditions or those engaged in repetitive activities that stress the tendons. Accurate coding is essential for proper treatment reimbursement and tracking of outcomes.
Detailed operative notes, pre-operative assessments, and post-operative follow-ups are essential.
Patients presenting with acute pain and loss of function in the upper arm, often after repetitive use or with underlying inflammatory conditions.
Ensure that the documentation clearly states the spontaneous nature of the rupture and any associated conditions.
Comprehensive rehabilitation plans and progress notes detailing functional assessments.
Patients recovering from tendon repair surgery requiring rehabilitation to regain strength and mobility.
Document the patient's functional limitations and progress towards recovery to support coding for therapy services.
Used when performing surgical repair of a ruptured flexor tendon.
Operative report detailing the procedure, including the tendon involved and repair technique.
Orthopedic surgeons must document the specifics of the tendon repair to ensure accurate coding.
Common causes include underlying inflammatory conditions such as tenosynovitis, degenerative changes in the tendon, and repetitive stress on the tendons without prior trauma.
