329: Laceration of extensor muscle, fascia and tendon of unspecified finger at wrist and hand level.
Surgical repair of a lacerated or torn extensor tendon is called extensor tendon repair. An extensor tendon repair surgery can be performed under either regional or general anesthesia.
Extensor tendons run just underneath the skin along the back of the hands and wrists. They control the hand's ability to straighten the fingers and wrists. A mallet finger injury happens when a finger is jammed, causing an extensor tendon to rupture at the base of the finger joint.
Spontaneous rupture of unspecified tendon M66. 9 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM M66. 9 became effective on October 1, 2021.
Extensor tendon lacerations occur when an object penetrates the tissues of the hand and severs the tendons on the back of the hand or fingers. This damage may be intentional or accidental, and often involves broken glass, jagged metal, or sharp tools. Mallet Finger refers to a drooping end-joint of a finger.
The extensor tendon repair code is 25270—Repair, tendon or muscle, extensor, forearm and/or wrist; primary, single, each tendon or muscle.
The index and small finger have two tendons, the long and ring fingers only have one extensor tendon, and the thumb has two extensors, but they attach at different joints.
Extensor tendons, located on the back of the hand and fingers, allow you to straighten your fingers and thumb.
The extensor tendons are strong smooth cords that straighten the fingers by connecting the muscles of the forearm and hand to the bones in the fingers and thumb. The extensor tendons are just under the skin and are easily injured by any cut across the back of the wrist hand or fingers.
Flexor tendons run from the forearm to the ends of the fingers across the palm side of the hand. They control the ability to bend fingers down to the palm (for example to make a fist, grip, or pinch objects). When these tendons are cut or injured, it can be impossible to bend the fingers or thumb.
Tendon and ligament tears or ruptures are injuries to the soft tissues that connect muscles and joints. Common symptoms of tendon and ligament tears are pain and swelling. You may also hear or feel a pop when you tear the tissue. Treatments can include a brace, medicine, or surgical repair.
Unspecified disorder of synovium and tendon, unspecified site. M67. 90 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM M67.
