M76.31 Iliotibial band syndrome, right leg

ICD10CM code

#### Name of the Condition
- Common Name: Iliotibial Band Syndrome (ITBS), Right Leg
- Medical Term: Right Leg Iliotibial Band Friction Syndrome

#### Summary
- Iliotibial Band Syndrome (ITBS) is a common injury involving the iliotibial band, a ligament extending from the hip to the shin, particularly affecting the outer part of the knee. It is notably painful and often affects athletes, particularly runners and cyclists, on their right leg.

#### Causes
- ITBS is primarily caused by repetitive knee bending during activities like running and cycling. This repetitive motion can lead to irritation and inflammation where the band rubs against the knee structure.

#### Risk Factors
- Engaging in high-impact activities like running, especially on inclines.
- Poorly aligned or flat feet, weak hip muscles, or inadequate stretching.
- Sudden increases in activity intensity or duration without adequate conditioning.
- Running on uneven surfaces or wearing improper footwear.

#### Symptoms
- Pain on the outer part of the knee, especially when the foot strikes the ground.
- Tenderness over the iliotibial band.
- Swelling or redness around the knee.
- Increased pain during activities or when bending the knee.

#### Diagnosis
- A physical examination focusing on the knee and hip movement.
- Patient history regarding physical activities.
- Imaging tests such as MRI may be used to rule out other conditions but are not always necessary.

#### Treatment Options
- Rest and avoidance of aggravating activities.
- Ice therapy to reduce inflammation and pain.
- Anti-inflammatory medications like NSAIDs.
- Physical therapy to strengthen surrounding muscles and improve flexibility.
- In severe cases, corticosteroid injections or surgery might be recommended.

#### Prognosis and Follow-Up
- With appropriate treatment and management, ITBS often improves within weeks to months.
- Regular monitoring and physical therapy can prevent recurrence.
- Long-term prognosis is generally good with lifestyle modifications.

#### Complications
- Chronic pain if not treated and managed.
- Reduced performance or ability to participate in activities.
- Possible progression to other knee-related injuries.

#### Lifestyle & Prevention
- Gradual increase in exercise intensity.
- Incorporating strength training and stretching exercises.
- Using proper footwear and replacing worn-out shoes.
- Running on softer, flat surfaces can help reduce the risk.

#### When to Seek Professional Help
- Persistent pain after a few weeks of self-care.
- Severe pain affecting daily activities.
- Swelling or redness persists despite rest and treatment.

#### Tips for Medical Coders
- Verify laterality as ITBS can occur in both legs; ensure coding accurately reflects the affected side.
- Utilize ICD code M76.31 specifically for iliotibial band syndrome of the right leg.
- Double-check for other knee injuries that could be contributing to symptoms to avoid miscoding.
