Rupture of popliteal cyst
ICD-10 M66.0 is a billable code used to indicate a diagnosis of rupture of popliteal cyst.
A popliteal cyst, also known as a Baker's cyst, is a fluid-filled sac that forms behind the knee, typically due to the accumulation of synovial fluid. This condition often arises from underlying knee joint disorders such as osteoarthritis, rheumatoid arthritis, or meniscal tears, which lead to increased synovial fluid production. When the cyst ruptures, it can cause sudden swelling and pain in the knee and calf region, mimicking deep vein thrombosis (DVT) symptoms. The rupture may lead to fluid leakage into the surrounding tissues, resulting in inflammation and discomfort. Diagnosis is usually confirmed through physical examination and imaging studies, such as ultrasound or MRI. Treatment options may include conservative management with rest, ice, compression, and elevation (RICE), as well as aspiration of the cyst or corticosteroid injections. In some cases, surgical intervention may be necessary to address the underlying cause or to remove the cyst. Accurate coding for a rupture of a popliteal cyst is essential for proper reimbursement and to reflect the complexity of the patient's condition.
Detailed notes on the patient's history, physical examination findings, imaging results, and treatment plan.
Patients presenting with knee pain and swelling, particularly after physical activity or trauma.
Ensure that the documentation clearly distinguishes between the cyst and other knee pathologies.
Comprehensive assessment of underlying inflammatory conditions and their impact on the cyst.
Patients with a history of rheumatoid arthritis presenting with knee swelling.
Document the relationship between systemic conditions and local manifestations.
Used when aspirating a ruptured popliteal cyst.
Document the indication for aspiration, the amount of fluid removed, and any complications.
Orthopedic specialists should ensure that the procedure is well-documented to support the diagnosis.
Common symptoms include sudden swelling behind the knee, pain in the knee or calf, and sometimes a feeling of tightness or fullness in the area.
Diagnosis typically involves a physical examination and imaging studies such as ultrasound or MRI to confirm the presence of a ruptured cyst.
Treatment may include conservative measures like rest and ice, aspiration of the cyst, corticosteroid injections, or surgical intervention if necessary.
