    ICD-10-CM Code For Other Disorders Of Cartilage: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group M94 includes other disorders of cartilage such as chondromalacia, localized cartilage lesions, and other specified cartilage pathologies affecting joint surfaces and related structures. These ICD-10-CM diagnosis codes are used to document clinical encounters involving cartilage degeneration, localized cartilage injury, and associated joint symptoms, capturing disease severity and anatomic involvement. Accurate coding within the ICD-10-CM M94 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM M94: Other Disorders Of Cartilage Overview

    The ICD-10-CM M94 diagnosis group covers disorders affecting cartilage tissues, including localized and degenerative cartilage conditions of joints and related structures. These conditions primarily involve the musculoskeletal system and can affect joint function and mobility. Accurate coding matters because it ensures complete clinical documentation and supports appropriate reimbursement for services related to cartilage pathology.

    Typical Clinical Scenarios

    • An elderly patient with progressive anterior knee pain, crepitus, and intermittent swelling over several years that worsens with climbing stairs and prolonged standing seeks evaluation in primary care; physical exam shows quadriceps atrophy and a positive patellofemoral grind test, and radiographs/MRI demonstrate degeneration or fissuring of the patellar articular cartilage consistent with chronic chondral degeneration, so a disorder of cartilage diagnosis is assigned. Typical codes: M94.0, M94.1
    • A middle-aged recreational runner presents to urgent care after acute onset of lateral knee pain and a popping sensation during a trail run with immediate swelling and difficulty bearing weight; MRI reveals a traumatic chondral flap lesion of the lateral femoral condyle requiring orthopedics referral and possible arthroscopic debridement, prompting assignment of an acute cartilage injury code. Typical codes: M94.211, M94.219
    • A patient with rheumatoid arthritis being seen in rheumatology for worsening joint deformities has persistent shoulder pain and limited range of motion; imaging demonstrates secondary cartilage loss and degenerative changes of the glenohumeral joint attributed to chronic inflammatory arthropathy, documented as a comorbid disorder of cartilage when coordinating care and procedures. Typical codes: M94.241, M94.249
