M75.0 Adhesive capsulitis of shoulder

Name of the Condition

• Common Name: Frozen Shoulder
• Medical Term: Adhesive Capsulitis of Shoulder
• ICD Code: M75.0

Summary

Adhesive capsulitis of the shoulder, commonly known as frozen shoulder, is a condition characterized by stiffness and pain in the shoulder joint. Over time, the shoulder becomes increasingly difficult to move. This condition typically progresses through stages, starting with pain and stiffness and gradually improving over months to years.

Causes

The exact cause of adhesive capsulitis is not fully understood. It may develop after shoulder injury, surgery, or due to prolonged shoulder immobility. It can also be idiopathic, where no specific cause is identified. The condition involves thickening and tightening of the shoulder joint capsule, which restricts movement.

Risk Factors

• Age: Most common in people aged 40 to 60.
• Gender: More prevalent in women than men.
• Health conditions: Higher occurrence in individuals with diabetes, thyroid disorders, and cardiovascular diseases.
• Immobility: Prolonged immobility of the shoulder, often after surgery or fracture.

Symptoms

• Gradual onset of shoulder pain and stiffness.
• Limited range of motion in the shoulder.
• Difficulty performing daily activities that involve lifting the arm.

Diagnosis

Diagnosis involves a physical examination to assess shoulder movement and pain levels. Imaging tests like X-rays or MRI may be used to rule out other conditions such as arthritis or rotator cuff tears. Clinical history, including any prior shoulder injuries or surgeries, is also evaluated.

Treatment Options

• Physical Therapy: Exercises to improve range of motion and strength.
• Medications: NSAIDs for pain and inflammation.
• Corticosteroid Injections: To reduce inflammation and pain.
• Joint Distension: Injecting sterile fluid into the joint to stretch the capsule.
• Surgery: In severe cases, arthroscopic surgery may be performed to release the tight tissues.

Prognosis and Follow-Up

Most cases of adhesive capsulitis improve over time, though recovery can take several months to years. Early treatment and consistent physical therapy often lead to better outcomes. Follow-up appointments are important to monitor progress and adjust treatment plans as needed.

Complications

• Prolonged stiffness and limited mobility.
• Chronic pain.
• Reduced quality of life due to difficulty performing daily activities.

Lifestyle & Prevention

• Maintain shoulder mobility through regular exercise.
• Avoid prolonged immobility, especially after surgery or injury.
• Manage underlying health conditions like diabetes or thyroid disorders.
• Use proper posture and ergonomics to reduce shoulder strain.

When to Seek Professional Help

Seek medical attention if shoulder pain and stiffness worsen, or if you experience significant difficulty moving your arm. Early intervention can help prevent long-term complications.

Tips for Medical Coders

When coding for adhesive capsulitis of the shoulder (M75.0), ensure documentation supports the diagnosis, including clinical findings, symptoms, and any relevant history. Note the absence of laterality (right/left) in this code, as it represents a generalized condition. Verify that no other specific shoulder conditions are documented that would require a more detailed code.
