Other soft tissue disorders (M70-M79)

ICD-10 codes M70-M79 cover various soft tissue disorders excluding bone and joint diseases, including conditions affecting tendons, bursae, and connective tissue primarily caused by use, overuse, infection, or inflammation. These codes capture a broad range of diagnoses from bursitis and tendonitis to fibroblastic disorders and enthesopathies.

This range includes M70 for soft tissue disorders related to overuse and pressure, such as crepitant synovitis of the hand and wrist, bursitis in multiple locations (e.g., elbow, shoulder, hip), and specific conditions like trochanteric bursitis ("greater trochanteric pain syndrome"). The M71 series addresses bursopathies including abscesses and cysts of bursae, while M72 codes fibroblastic disorders like Dupuytren's contracture and necrotizing fasciitis. Shoulder lesions, including adhesive capsulitis and rotator cuff tears, fall under M75. Enthesopathies of the lower limbs, tendon inflammation, and related syndromes (e.g., iliotibial band syndrome) are categorized in M76. Other enthesopathies such as medial and lateral epicondylitis are covered by M77. The M79 series captures other and unspecified soft tissue disorders, including myalgia, fibromyalgia, neuralgia, and pain located in limbs like the hands and feet.
