ICD-10: M11.269

ICD-10 code M11.269 refers to "Other chondrocalcinosis, unspecified knee." This diagnosis falls under the broader category of chondrocalcinosis, which is characterized by the deposition of calcium pyrophosphate dihydrate (CPPD) crystals in the cartilage. This condition can lead to joint pain and inflammation, often resembling gout, and is commonly associated with pseudogout.

Clinical Description

Definition

Chondrocalcinosis is a condition where calcium pyrophosphate crystals accumulate in the cartilage, leading to joint inflammation and pain. The term "other chondrocalcinosis" indicates that the specific type of chondrocalcinosis is not classified elsewhere, and in this case, it is unspecified for the knee joint.

Symptoms

Patients with chondrocalcinosis may experience:
- Joint Pain: Often acute and can mimic gout attacks.
- Swelling: Affected joints may become swollen and tender.
- Stiffness: Reduced range of motion in the affected joint, particularly after periods of inactivity.
- Warmth and Redness: The skin over the affected joint may appear warm and red.

Affected Population

Chondrocalcinosis is more prevalent in older adults, particularly those over the age of 60. It can occur in both men and women, but some studies suggest a higher incidence in men.

Diagnosis

Diagnosis of chondrocalcinosis typically involves:
- Clinical Evaluation: Assessment of symptoms and medical history.
- Imaging Studies: X-rays may reveal calcifications in the cartilage, particularly in the knee joint.
- Joint Aspiration: Synovial fluid analysis can help confirm the presence of CPPD crystals.

Treatment

Management of chondrocalcinosis focuses on alleviating symptoms and may include:
- Nonsteroidal Anti-Inflammatory Drugs (NSAIDs): To reduce pain and inflammation.
- Corticosteroids: Injections may be used for severe inflammation.
- Physical Therapy: To improve joint function and mobility.
- Lifestyle Modifications: Weight management and low-impact exercises can help reduce stress on the joints.

Conclusion

ICD-10 code M11.269 is essential for accurately documenting cases of chondrocalcinosis affecting the knee when the specific type is not otherwise classified. Understanding this condition is crucial for healthcare providers to ensure appropriate diagnosis and management, ultimately improving patient outcomes. Regular follow-up and monitoring are recommended to manage symptoms effectively and prevent complications associated with joint degeneration.

The ICD-10 code M11.269 refers to "Other chondrocalcinosis, unspecified knee," which is a condition characterized by the deposition of calcium pyrophosphate dihydrate (CPPD) crystals in the joint, leading to various clinical manifestations. Understanding the clinical presentation, signs, symptoms, and patient characteristics associated with this condition is crucial for accurate diagnosis and management.

Clinical Presentation

Chondrocalcinosis typically presents with joint pain and swelling, particularly in the knee, which is the focus for the M11.269 code. The condition can be asymptomatic in some patients, while others may experience acute episodes resembling gout attacks.

Signs and Symptoms

1. Joint Pain: Patients often report sudden onset of pain in the knee, which can be severe and debilitating. This pain may be similar to that experienced during a gout attack, but it is due to the presence of CPPD crystals rather than uric acid crystals.

2. Swelling and Inflammation: The affected knee may exhibit significant swelling, warmth, and tenderness. This inflammation can lead to decreased range of motion and difficulty in weight-bearing activities.

3. Stiffness: Patients may experience stiffness in the knee joint, particularly after periods of inactivity or in the morning upon waking.

4. Recurrent Episodes: Some individuals may have recurrent episodes of pain and swelling, which can vary in frequency and intensity.

5. Chronic Symptoms: In chronic cases, patients may develop persistent knee pain and functional impairment due to ongoing joint damage.

Patient Characteristics

Chondrocalcinosis is more commonly observed in certain patient populations:

• Age: The condition is often seen in older adults, particularly those over the age of 60, as the prevalence of CPPD crystal deposition increases with age.

• Gender: There is a slight male predominance in the incidence of chondrocalcinosis, although it can affect both genders.

• Comorbidities: Patients with metabolic disorders, such as hyperparathyroidism, hemochromatosis, or hypothyroidism, may have a higher risk of developing chondrocalcinosis. Additionally, individuals with osteoarthritis may also present with this condition.

• Family History: A family history of chondrocalcinosis or related conditions may increase the likelihood of developing the disease, suggesting a genetic predisposition.

Conclusion

In summary, ICD-10 code M11.269 encompasses a range of clinical presentations associated with other chondrocalcinosis of the unspecified knee. Patients typically present with joint pain, swelling, and stiffness, particularly in older adults. Understanding these characteristics is essential for healthcare providers to facilitate accurate diagnosis and effective management of the condition. Early recognition and treatment can help alleviate symptoms and improve the quality of life for affected individuals.
