Musculoskeletal condition M87.063 — ICD-10 M87.063
Musculoskeletal condition M87.063
Overview
ICD-10 code M87.063 refers to osteonecrosis of the femoral head due to chronic use of corticosteroids. This condition is characterized by the death of bone tissue resulting from a lack of blood supply, often exacerbated by prolonged corticosteroid therapy. Osteonecrosis can lead to severe joint pain, dysfunction, and ultimately, joint collapse if not addressed promptly. Understanding this condition is crucial for clinicians, rehabilitation providers, and patients alike, as it has significant implications for treatment and recovery.
The femoral head is the rounded top portion of the femur (thigh bone) that fits into the acetabulum of the pelvis, forming the hip joint. This joint is a ball-and-socket structure that allows for a wide range of motion while bearing significant weight during activities such as walking, running, and jumping.
Key Anatomical Features:
- Femoral Head: The spherical part of the femur that articulates with the acetabulum.
- Acetabulum: The socket in the pelvis that receives the femoral head.
- Articular Cartilage: A smooth tissue covering the ends of bones in joints, facilitating smooth movement.
- Subchondral Bone: The layer of bone just beneath the cartilage that provides structural support.
Biomechanics:
The hip joint bears considerable load during weight-bearing activities. The integrity of the femoral head is critical for maintaining joint function and stability. When blood supply is compromised due to factors such as corticosteroid use, it can lead to bone death and subsequent structural failure of the joint.
Comman symptoms
The symptoms of osteonecrosis can vary based on severity and stage:
Early Stage (Mild):
- Mild discomfort in the hip or groin area
- Pain may be intermittent and often worsens with activity
- No significant limitations in mobility
Moderate Stage:
- Increased pain intensity during weight-bearing activities
- Stiffness in the hip joint
- Pain radiating down the thigh or into the knee
- Noticeable limitations in range of motion
Advanced Stage (Severe):
- Constant pain even at rest
- Severe limitations in mobility; difficulty walking or standing
- Joint swelling or visible deformity
- Potential development of secondary osteoarthritis
Red Flag
Clinicians should remain vigilant for red flags indicating complications or need for referral:
Red Flags:
- Sudden onset of severe pain not relieved by rest or medication.
- Rapid deterioration in joint function or mobility.
- Signs of infection (fever, swelling).
Referral Criteria:
Patients should be referred to an orthopedic specialist if:
- There is suspicion of advanced disease requiring surgical intervention.
- Non-operative management fails after an adequate trial period (typically 6–8 weeks).
- There are signs of significant joint degeneration on imaging studies.

Causes & Risk Factors
Osteonecrosis occurs when there is an interruption in blood flow to the bone. In the context of chronic corticosteroid use, several mechanisms contribute to this condition:
Pathophysiology:
- Vascular Compromise: Corticosteroids can induce fat deposition in blood vessels, leading to vascular occlusion.
- Bone Remodeling Disruption: These medications interfere with osteoblast function (bone formation) and promote osteoclast activity (bone resorption), resulting in a net loss of bone density.
- Increased Intraosseous Pressure: Fatty marrow infiltration increases pressure within the bone, further impairing blood flow.
Risk Factors:
- Chronic Corticosteroid Use: High doses or prolonged therapy increases risk significantly.
- Alcohol Consumption: Excessive alcohol intake can also contribute to vascular compromise.
- Trauma: Previous injuries to the hip may predispose individuals to osteonecrosis.
- Underlying Conditions: Disorders such as lupus or sickle cell disease increase susceptibility.
Diagnostic Workup
A thorough diagnostic workup is essential for confirming osteonecrosis due to corticosteroid use:
History Taking:
- Detailed medication history focusing on corticosteroid use duration and dosage.
- Inquiry about alcohol consumption and any history of trauma.
Physical Examination:
- Assessment of hip range of motion.
- Evaluation for tenderness over the hip joint.
- Gait analysis to identify compensatory patterns.
Imaging Studies:
- X-rays: Initial imaging modality; may show subtle changes in early stages.
- MRI: Gold standard for early diagnosis; reveals areas of necrosis and edema.
- CT Scan: Useful for assessing advanced changes or planning surgical intervention.
Treatment & Rehabilitation
Management of osteonecrosis involves both conservative measures and potential surgical interventions depending on severity:
Phase 1: Initial Management (Weeks 1–4)
- Goals: Reduce pain, improve function.
- Interventions:
- Activity modification (avoid weight-bearing activities).
- NSAIDs for pain relief.
- Physical therapy focused on gentle range-of-motion exercises.
Phase 2: Strengthening Phase (Weeks 5–8)
- Goals: Restore strength and mobility.
- Exercises:
- Isometric quadriceps contractions.
- Hip abduction/adduction exercises using resistance bands.
- Aquatic therapy for low-impact strengthening.
Phase 3: Progressive Loading Phase (Weeks 9–12)
- Goals: Gradual return to functional activities.
- Exercises:
- Weight-bearing exercises (e.g., step-ups).
- Balance training activities (e.g., single-leg stands).
- Resistance training focusing on lower extremity muscles.
Phase 4: Functional Rehabilitation (Weeks 13+)
- Goals: Return to pre-injury level of activity.
- Exercises:
- Sport-specific drills if applicable.
- Plyometric exercises for power development.
- Continued strength training with progression in load.
Surgical options may include core decompression or total hip arthroplasty depending on the extent of necrosis and patient age.
Prevention
Preventing musculoskeletal conditions such as those classified under ICD-10 code M87.063 (Avascular necrosis of the bone, unspecified site) requires a multifaceted approach that includes ergonomic adjustments, lifestyle modifications, and effective risk management strategies. Key evidence-based strategies include:
- Ergonomic Interventions: Ensure proper workstation setups to reduce strain on joints and bones. This includes using adjustable chairs, desks, and equipment that promote good posture.
- Regular Exercise: Engage in low-impact physical activities like swimming or cycling to strengthen bones and muscles while minimizing stress on joints.
- Healthy Diet: Adopt a balanced diet rich in calcium and vitamin D to support bone health. Foods such as dairy products, leafy greens, and fortified cereals can be beneficial.
- Weight Management: Maintain a healthy weight to reduce the stress placed on weight-bearing joints, which can help prevent conditions leading to avascular necrosis.
- Risk Factor Management: Identify and manage risk factors such as excessive alcohol consumption, smoking, and long-term use of corticosteroids, which can contribute to bone health deterioration.
Coding Examples
Patient presents with chronic hip pain and a history of corticosteroid use for rheumatoid arthritis. Imaging reveals signs of avascular necrosis in the femoral head. Code as M87.063 because the diagnosis aligns with the ICD-10 classification for avascular necrosis of the bone, and the patient's history of corticosteroid use is a recognized risk factor for this condition.
Audit & Compliance
To ensure compliance and prevent claim denials for the use of ICD-10 code M87.063, the following documentation elements are critical:
- Comprehensive History and Physical Exam: Document detailed patient history, including relevant risk factors (e.g., corticosteroid use, prior trauma).
- Diagnostic Imaging Results: Include reports of X-rays, MRI, or CT scans that confirm the diagnosis of avascular necrosis.
- Treatment Plan Documentation: Clearly outline the treatment plan, including referrals, physical therapy, and any surgical considerations.
- Follow-up Notes: Maintain records of follow-up visits to track the progression of the condition and response to treatment.
Clinical Example
Subjective: A 54-year-old female patient reports persistent pain in her right hip that has progressively worsened over the past six months. She describes the pain as deep, aching, and worsened by weight-bearing activities. The patient has a history of systemic lupus erythematosus and has been on corticosteroid therapy for the past three years. Objective: Physical examination reveals limited range of motion in the right hip, tenderness on palpation over the greater trochanter, and a slight limp. X-rays show radiolucent areas in the femoral head consistent with avascular necrosis. Assessment: Avascular necrosis of the right hip (ICD-10 code M87.063). The condition is likely secondary to prolonged corticosteroid therapy. Plan: Recommend referral to an orthopedic specialist for further evaluation and management options, including potential surgical intervention. Initiate physical therapy focused on pain management and maintaining hip mobility. Schedule follow-up in 6 weeks to assess progress.
Differential Diagnoses
Differentiating osteonecrosis from other conditions is crucial for appropriate management:
- ICD-10 Code M16.0 - Primary osteoarthritis of the hip
- ICD-10 Code M25.551 - Pain in right hip
- ICD-10 Code M25.552 - Pain in left hip
- ICD-10 Code M76.821 - Trochanteric bursitis, right side
- ICD-10 Code M76.822 - Trochanteric bursitis, left side
Each differential diagnosis has distinct clinical features that must be evaluated through history taking, physical examination, and imaging studies.
Documentation Best Practices
Accurate documentation is essential for appropriate billing under ICD-10 code M87.063:
Documentation Tips:
- Clearly document all relevant patient history related to corticosteroid use, including dosage and duration.
- Record all physical examination findings systematically.
- Include details from imaging studies supporting your diagnosis.
Billing Guidance:
When billing for services related to osteonecrosis:
- Use M87.063 as the primary diagnosis code when treating osteonecrosis due to corticosteroids.
- Ensure that all associated codes for any secondary conditions are also included (e.g., M25.551 for pain).
- Maintain thorough documentation in EMR systems to support claims against audits.
