ICD-10: M70.50

The ICD-10-CM code M70.50 refers to "Other bursitis of knee, unspecified knee." This code is used in medical coding to classify a specific type of bursitis affecting the knee joint, where the exact cause or type of bursitis is not specified. Below is a detailed overview of this condition, including its clinical description, symptoms, causes, and treatment options.

Clinical Description

Bursitis is an inflammation of the bursae, which are small, fluid-filled sacs that cushion the bones, tendons, and muscles near joints. The knee joint contains several bursae, and when these become inflamed, it can lead to pain and discomfort. The term "other bursitis" indicates that the condition does not fall under the more commonly recognized types of bursitis, such as prepatellar bursitis (housemaid's knee) or infrapatellar bursitis (clergyman's knee) but still affects the knee area.

Symptoms

Patients with M70.50 may experience a variety of symptoms, including:

• Localized Pain: Pain around the knee joint, which may worsen with movement or pressure.
• Swelling: Visible swelling in the knee area due to inflammation of the bursae.
• Stiffness: Reduced range of motion in the knee, making it difficult to bend or straighten the leg.
• Tenderness: Sensitivity to touch around the affected area.
• Warmth: The skin over the knee may feel warm to the touch, indicating inflammation.

Causes

The causes of bursitis in the knee can vary widely and may include:

• Repetitive Motion: Activities that involve repetitive bending or kneeling can irritate the bursae.
• Injury: Trauma to the knee, such as a fall or direct blow, can lead to bursitis.
• Infection: In some cases, bursitis can be caused by an infection in the bursa, although this is less common.
• Underlying Conditions: Conditions such as rheumatoid arthritis or gout can predispose individuals to bursitis.

Diagnosis

Diagnosis of M70.50 typically involves a thorough medical history and physical examination. Healthcare providers may also use imaging studies, such as X-rays or MRI, to rule out other conditions and confirm the presence of bursitis.

Treatment Options

Treatment for bursitis of the knee generally focuses on relieving symptoms and addressing the underlying cause. Common treatment strategies include:

• Rest: Avoiding activities that exacerbate the condition.
