About the S40–S49 Code Range

ICD-10 codes S40 to S49 classify a wide range of injuries to the shoulder and upper arm. These include superficial injuries, wounds, fractures, dislocations, nerve injuries, vascular injuries, muscle and tendon injuries, and crushing injuries. The codes provide detailed specificity based on the injury type and affected side (right, left, or unspecified), as well as the encounter stage such as initial, subsequent, or sequelae.

This range covers superficial trauma like contusions, abrasions, and insect or animal bites, with codes such as S40 representing contusions and superficial injuries, including synonyms like "hematoma of shoulder region" or "contusion of clavicular area." Open wounds and lacerations are categorized in S41, detailing whether foreign bodies are involved. Fractures to the clavicle, scapula, and parts of the humerus—including specified types like displaced, nondisplaced, comminuted, or Salter-Harris physeal fractures—are covered extensively under S42 and S49. Dislocations and sprains of the shoulder girdle joints, including the shoulder, acromioclavicular, and sternoclavicular joints, are coded in S43. Nerve injuries at shoulder and upper arm level involving the ulnar, median, radial, axillary, musculocutaneous, and sensory nerves are classified in S44. Blood vessel injuries to axillary and brachial arteries and veins use codes in S45. Muscle and tendon injuries to key structures like the rotator cuff, long head of biceps, other parts of biceps, and triceps are found in S46. Lastly, crushing injuries and traumatic amputations of the shoulder and upper arm fall under S47 and S48, respectively.

These codes are essential for precisely identifying injury location and type to assist in clinical documentation, billing, and treatment planning for shoulder and upper arm injuries.
