Name of the Condition

• Other tear of medial meniscus, current injury, right knee, subsequent encounter

Summary

• The medial meniscus is a cartilage structure in the knee that acts as a cushion. A tear refers to damage to this cartilage, which can cause pain and affect knee mobility. This condition specifies a right knee injury that has been previously treated but requires further medical care.

Causes

• Medial meniscus tears can result from acute trauma, such as twisting or sudden impact during activities like sports. Degenerative tears can also occur due to wear and tear over time.

Risk Factors

• Age, particularly in older adults due to degeneration.
• Engaging in high-impact sports or physical activities.
• Previous knee injuries.
• Poor muscle conditioning or balance.

Symptoms

• Pain along the inner side of the knee.
• Swelling or stiffness in the knee joint.
• Limited range of motion.
• A popping sensation at the time of injury.
• Difficulty in extending the knee fully.

Diagnosis

• Physical examination focusing on knee tenderness and motion.
• Imaging tests such as MRI to visualize the meniscus.
• Arthroscopy in some cases to inspect the knee joint directly.

Treatment Options

• R.I.C.E. (Rest, Ice, Compression, Elevation) for immediate relief.
• Physical therapy to strengthen knee muscles and restore motion.
• Medications like NSAIDs to reduce pain and inflammation.
• Surgical options, like arthroscopic repair, if conservative treatments fail.

Prognosis and Follow-Up

• Many patients recover fully with appropriate treatment, though recovery time varies.
• Regular follow-up is essential to monitor healing and adjust treatment plans.

Complications

• Persistent pain or swelling.
• Limited knee mobility.
• Increased risk of knee osteoarthritis in the future.

Lifestyle & Prevention

• Maintaining a healthy weight to lessen knee stress.
• Strengthening exercises for knee stability.
• Wearing appropriate protective gear during sports.
• Avoiding sudden and extreme movements which can strain the knee.

When to Seek Professional Help

• Severe pain, swelling, or inability to move the knee normally.
• Symptoms persist despite initial treatment.

Tips for Medical Coders

• Ensure the code reflects a subsequent encounter for continued treatment.
• Verify the laterality (right knee) in medical documentation.
• Distinguish from acute or chronic conditions that may require different codes.
