ICD-10: M24.611

ICD-10 code M24.611 specifically refers to "Ankylosis, right shoulder," which is classified under the category of other joint disorders. Here are the clinical details and descriptions associated with this code:

• Definition: Ankylosis is a condition characterized by the stiffening or immobility of a joint due to fusion of the bones. In the case of M24.611, it specifically pertains to the right shoulder joint.

• Classification: This code falls under the broader category of "Other joint disorders" within the ICD-10 classification system, which is maintained by the World Health Organization (WHO) [1][2].

• Clinical Significance: The diagnosis of ankylosis indicates that the right shoulder joint has become rigid, which can significantly impact a patient's range of motion and overall functionality. This condition may arise from various underlying causes, including inflammatory diseases, trauma, or degenerative conditions.

• Billable Code: M24.611 is a billable diagnosis code, meaning it can be used for billing and reimbursement purposes in healthcare settings. It is valid for use during the current fiscal year, specifically from October 1, 2024, through September 30, 2025 [10][12].

• Related Codes: Other related codes include M24.612 for ankylosis of the left shoulder and M24.619 for unspecified shoulder ankylosis, indicating that similar conditions can affect other joints or be unspecified [5][8].

Understanding this code is crucial for healthcare providers in diagnosing and managing patients with joint disorders, particularly those affecting the shoulder.

ICD-10 code M24.611 refers to "Ankylosis, right shoulder," which is a condition characterized by the stiffening or immobility of the shoulder joint. Here are the clinical presentations, signs, symptoms, and patient characteristics associated with this diagnosis:

Clinical Presentation

• Ankylosis: This condition results in the fusion of the joint surfaces, leading to a loss of normal movement. In the case of the right shoulder, this can severely limit the range of motion.
• Pain: Patients may experience chronic pain in the shoulder area, which can be exacerbated by movement or pressure on the joint.

Signs and Symptoms

• Limited Range of Motion: Patients typically exhibit a significant reduction in the ability to move the shoulder, particularly in abduction and external rotation.
• Stiffness: A feeling of stiffness in the shoulder joint is common, making it difficult for patients to perform daily activities.
• Swelling: There may be swelling around the joint, although this is not always present.
• Muscle Atrophy: Over time, the muscles surrounding the shoulder may weaken and atrophy due to disuse.
• Functional Impairment: Patients often report difficulties with activities that require shoulder movement, such as reaching overhead or behind the back.

Patient Characteristics

• Age: Ankylosis can occur at any age, but it is more prevalent in middle-aged and older adults, particularly those with a history of joint injuries or inflammatory conditions.
• History of Trauma: Patients may have a history of trauma or injury to the shoulder, which can predispose them to developing ankylosis.
• Underlying Conditions: Conditions such as rheumatoid arthritis or other inflammatory diseases can increase the risk of joint ankylosis.
• Gender: There may be a slight male predominance in certain types of shoulder ankylosis, although this can vary based on underlying causes.

Conclusion

Ankylosis of the right shoulder, as indicated by ICD-10 code M24.611, presents with significant limitations in movement, pain, and functional impairment, often influenced by the patient's age, history of trauma, and underlying health conditions. Understanding these aspects is crucial for effective diagnosis and management of the condition.

The ICD-10 code M24.611 specifically refers to "Ankylosis, right shoulder." Here are some alternative names and related terms associated with this diagnosis:

• Ankylosis of the right shoulder: This is a direct synonym for the condition, emphasizing the location.
• Shoulder ankylosis: A more general term that can refer to ankylosis in either shoulder but is often used in the context of the right shoulder when specified.
• Joint stiffness: While not specific to ankylosis, this term describes a common symptom associated with the condition.
• Frozen shoulder: This term is often used in a broader context but can relate to the immobility caused by ankylosis.
• Ankylosis of joint of shoulder region: A more technical term that describes the same condition.
• Ankylosis, shoulder region: Another variation that indicates the affected area.

These terms can be useful in understanding the condition and its implications in medical documentation and communication. The ICD-10 classification places this diagnosis under the category of "Other joint disorders" as per the World Health Organization (WHO) guidelines [5][10].

The ICD-10 code M24.611 is designated for the diagnosis of ankylosis of the right shoulder. The criteria for diagnosing this condition typically include:

• Clinical Evaluation: A thorough physical examination is essential to assess the range of motion in the shoulder joint. The presence of significant restriction in movement is a key indicator of ankylosis.

• Medical History: The patient's medical history should be reviewed for any previous injuries, surgeries, or conditions that could contribute to joint stiffness or ankylosis.

• Imaging Studies: Radiological examinations, such as X-rays or MRI, may be utilized to visualize the joint structure and confirm the presence of ankylosis. These imaging studies help in identifying any bony fusion or abnormal joint positioning.

• Exclusion of Other Conditions: It is important to rule out other potential causes of shoulder stiffness, such as adhesive capsulitis (frozen shoulder) or other arthropathies, to ensure an accurate diagnosis.

• Functional Assessment: Evaluating the impact of the condition on the patient's daily activities and overall function can also be part of the diagnostic criteria.

The code M24.611 is valid for use in medical billing and documentation, and it became effective on October 1, 2024, for the current fiscal year [10][12][14].

The standard treatment approaches for ankylosis of the right shoulder (ICD-10 code M24.611) typically focus on alleviating pain, improving mobility, and restoring function. Here are some common treatment options:

• Physical Therapy: A structured physical therapy program is often the first line of treatment. This may include exercises to improve range of motion, strength training, and modalities such as heat or cold therapy to reduce pain and inflammation.

• Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly prescribed to manage pain and inflammation. In some cases, corticosteroid injections may be used to provide more immediate relief.

• Surgical Intervention: If conservative treatments fail to provide relief, surgical options may be considered. This can include procedures such as:

• Arthrolysis: This involves the surgical release of the joint to improve mobility.

• Shoulder Replacement: In severe cases, a total or partial shoulder replacement may be necessary to restore function.

• Assistive Devices: The use of braces or splints may help support the shoulder and improve function during the rehabilitation process.

• Lifestyle Modifications: Patients are often advised to engage in low-impact activities that do not exacerbate their condition, along with maintaining a healthy weight to reduce stress on the joints.

These treatment approaches aim to enhance the quality of life for individuals with ankylosis of the right shoulder by addressing both the physical limitations and associated pain of the condition.
