Flexor Zones of the Hand Zone 1: Distal to FDP Insertion. Zone 2: Proximal A2 Pulley to FDP Insertion. Zone 3: Carpal Tunnel to Proximal A2 Pulley. Zone 4: Carpal Tunnel. Zone 5: Proximal to Carpal Tunnel.
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.
Flexor digitorum profundus (FDP) tendons They run down the forearm and within the carpal tunnel. The four tendons glide in sheaths along the hand and fingers and insert into the fingertip bone. These tendons run closer to the bone compared to the rest of the flexors in the hand and fingers.
ICD-10-CM Code for Synovitis and tenosynovitis M65.
If your flexor tendons are damaged, you'll be unable to bend one or more fingers. Tendon damage can also cause pain and inflammation (swelling) in your hand. In some cases, damage to the extensor tendons can be treated without the need for surgery, using a rigid support called a splint that's worn around the hand.
forearmFlexor carpi ulnaris (FCU) tendon Its muscle belly is in the forearm. The tendon travels along the inside of the forearm on the side of the small finger and crosses the wrist. It attaches to the wrist bone, the pisiform, and as well as the 5th hand bone.

Tendons of flexor digitorum sperficialis (FDS) and profundus (FDP) (with flexor policis longus) are located deeper respectively 1,2. Tendons of FDS and FDP are enclosed in a common synovial sheath, the ulnar bursa which is extended from wrist proximally to hand distally; and continues to synovial bursa of fifth finger.
Flexor tenosynovitis is the inflammation of the fluid-filled sheath that surrounds a tendon, i.e., the synovium. A flexor tendon, during chronic inflammation, may cause painful edema, and long-term degeneration resulting in knuckle pads or rarely flexor tendon ruptures [4,5].
Other synovitis and tenosynovitis, unspecified hand M65. 849 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 M65. 849 became effective on October 1, 2021.
Synovitis is a common condition meaning inflammation of the synovial lining of a joint or tendon sheath (the tunnel the tendon runs through). Tendon sheath synovitis is referred to as tenosynovitis. It is a generalised response of that particular tissue (the synovial lining) to a local problem e.g. injury or infection.
Without appropriate treatment, a flexor tendon injury can cause you to lose the use of your fingers, thumb or entire hand. A cut in this area of the hand may also involve important nerves and blood vessels, resulting in numbness or inadequate blood supply. Urgent surgery may be necessary.
If a deep cut occurs, damage to nerves or blood vessels may occur. This is very serious and requires immediate surgery to remedy.
The most profound symptom of Flexor Tendon Injuries is the inability to bend one or more of the joints of a finger. Pain may be more pronounced when the finger is bent. Tenderness, bruising, or swelling may be present on the palm side of the hand along the affected digit. In some cases the fingertip may go numb.
If your flexor tendons are damaged, you'll be unable to bend 1 or more fingers. Tendon damage can also cause pain and swelling (inflammation) in your hand. Sometimes, damage to the extensor tendons can be treated without the need for surgery, using a rigid support called a splint that's worn around the hand.
S66.1 Injury of flexor muscle, fascia and tendon of other and unspecified finger at wrist and hand level. S66.2 Injury of extensor muscle, fascia and tendon of thumb at wrist and hand level. S66.3 Injury of extensor muscle, fascia and tendon of other and unspecified finger at wrist and hand level.
S56 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail. The 2021 edition of ICD-10-CM S56 became effective on October 1, 2020. This is the American ICD-10-CM version of S56 - other international versions of ICD-10 S56 may differ. Code Also.
