Musculoskeletal condition M67.931 — ICD-10 M67.931
Musculoskeletal condition M67.931
Overview
ICD-10 code M67.931 refers to a specific type of musculoskeletal condition known as "Other specified disorders of synovium and tendon, right shoulder." This classification encompasses a variety of issues that may arise in the connective tissues surrounding joints and tendons, particularly in the shoulder region. These disorders can manifest through pain, inflammation, and functional impairment, significantly affecting the quality of life for those affected.
The shoulder is a highly mobile joint, which makes it susceptible to various injuries and conditions, particularly in active individuals or those engaged in repetitive overhead activities. Understanding the underlying anatomy, biomechanics, and pathophysiology is crucial for effective diagnosis and treatment.
The shoulder complex consists of several key anatomical structures:
- Glenohumeral Joint: The ball-and-socket joint formed by the humeral head and the glenoid cavity of the scapula.
- Rotator Cuff: A group of four muscles (supraspinatus, infraspinatus, teres minor, subscapularis) and their associated tendons that stabilize the shoulder.
- Bursa: Fluid-filled sacs that reduce friction between tissues; the subacromial bursa is particularly important in shoulder mechanics.
- Tendons: Connect muscles to bones; tendons in the shoulder are prone to inflammation and degeneration due to overuse or injury.
Biomechanically, the shoulder allows for a wide range of motion including flexion, extension, abduction, adduction, internal rotation, and external rotation. This mobility is balanced by stability provided by the rotator cuff and surrounding musculature. However, excessive use or acute trauma can lead to microtears or inflammation within these structures, contributing to conditions coded under M67.931.
Comman symptoms
Symptoms associated with M67.931 can vary significantly based on severity:
Mild Severity
- Pain: Mild discomfort during specific movements.
- Stiffness: Occasional stiffness after prolonged inactivity.
Moderate Severity
- Pain: Persistent pain during activities or at rest.
- Swelling: Noticeable swelling around the shoulder joint.
- Reduced Range of Motion: Difficulty performing overhead tasks.
Severe Severity
- Intense Pain: Severe pain that may radiate down the arm.
- Joint Instability: A feeling of instability or “giving way” in the shoulder.
- Significant Functional Impairment: Inability to perform daily activities such as dressing or reaching overhead.
Red Flag
Clinicians should be vigilant for red flags indicating serious underlying pathology that warrants immediate referral:
- Severe pain not alleviated by rest or medications.
- Significant loss of function or inability to perform daily activities.
- Signs of infection (fever, redness, swelling).
- Neurological symptoms such as numbness or tingling in the arm.
Referral to an orthopedic specialist may be necessary for surgical evaluation if conservative measures fail after an appropriate trial period.

However, excessive use or acute trauma can lead to microtears or inflammation within these structures, contributing to conditions coded under M67.931.
Causes & Risk Factors
Pathophysiologically, conditions classified under M67.931 often involve inflammatory processes within the synovium or tendons of the shoulder. Common mechanisms include:
- Overuse: Repetitive overhead activities can lead to microtrauma and subsequent inflammation.
- Trauma: Acute injuries from falls or sports can damage tendons or synovial tissue.
- Degeneration: Age-related changes can weaken tendons and synovial structures, making them more susceptible to injury.
Risk factors for developing these disorders include:
- Age: Older adults are more likely to experience degenerative changes.
- Occupation: Jobs requiring repetitive overhead work (e.g., construction, athletics) increase risk.
- Previous Injuries: A history of shoulder injuries can predispose individuals to further issues.
- Comorbidities: Conditions such as diabetes or rheumatoid arthritis can affect healing.
Diagnostic Workup
Diagnosis begins with a thorough clinical history followed by a physical examination. Key components include:
History
- Duration and onset of symptoms.
- Mechanism of injury (acute vs. chronic).
- Previous treatments attempted.
Physical Examination
- Inspection: Look for swelling, bruising, or deformity.
- Palpation: Assess for tenderness over specific tendons or bursa.
- Range of Motion Testing: Evaluate both active and passive range of motion.
- Special Tests:
- Neer’s test (impingement)
- Hawkins-Kennedy test (subacromial impingement)
- Empty can test (supraspinatus strength)
Imaging Studies
While not always necessary for initial diagnosis, imaging may be used to rule out other conditions:
- X-rays: To assess for bony abnormalities.
- MRI/Ultrasound: To evaluate soft tissue structures like tendons and bursae.
Treatment & Rehabilitation
Treatment for M67.931 typically follows a structured rehabilitation protocol divided into four phases:
Phase 1: Acute Phase (0-2 weeks)
Goals:
- Reduce pain and inflammation
- Protect the injured area
Interventions:
- Rest and activity modification
- Ice application for 15-20 minutes several times daily

Prevention
Preventing musculoskeletal conditions like M67.931, which pertains to unspecified disorders of the synovium and tendon, involves a multifaceted approach that emphasizes ergonomics, lifestyle modifications, and risk management.
- Ergonomics: Encourage proper workstation setup to promote good posture and reduce strain on muscles and joints. Utilize ergonomic chairs, adjustable desks, and tools designed to minimize repetitive motion injuries.
- Lifestyle Modifications: Advocate for regular physical activity to enhance muscle strength and flexibility. Encourage low-impact exercises such as swimming or cycling, which can alleviate stress on joints while improving overall fitness.
- Risk Management: Identify and mitigate risk factors in the workplace and daily activities by conducting ergonomic assessments and providing training on safe lifting techniques. Implementing regular breaks during repetitive tasks can also help in reducing strain.
- Education: Provide education on body mechanics and the importance of stretching before and after physical activity to maintain muscle elasticity and joint health.
- Health Monitoring: Regular medical check-ups can help in early detection and management of potential musculoskeletal issues.
Coding Examples
Patient presents with chronic pain in the left wrist and reports difficulty in performing daily activities due to swelling and tenderness. The physician performs a thorough examination and notes synovial inflammation in the wrist joint without a specified underlying condition. Code as M67.931 because the documentation indicates an unspecified disorder of the synovium indicative of a musculoskeletal condition affecting the wrist.
Audit & Compliance
To support medical necessity and prevent claim denials for ICD-10 code M67.931, the following key documentation elements must be included:
- Detailed Patient History: Include a thorough history of present illness detailing the onset, duration, and characteristics of symptoms.
- Physical Examination Findings: Document specific physical findings, including pain location, range of motion, and any observed swelling or tenderness.
- Assessment and Diagnosis: Clearly articulate the rationale for the diagnosis of an unspecified disorder of the synovium and tendon, supported by clinical findings.
- Treatment Plan: Outline the proposed treatment plan, including referrals to physical therapy or other interventions, and the expected outcomes.
- Follow-Up Documentation: Document any follow-up visits and changes in the patient's condition or response to treatment.
Clinical Example
Subjective: A 45-year-old female presents with complaints of persistent pain and stiffness in her right elbow, which has been ongoing for the past three months. She reports difficulty in gripping objects and experiences swelling at times. Objective: On examination, there is tenderness to palpation over the lateral epicondyle. Range of motion is slightly reduced, and swelling is noted. No signs of injury or trauma are present. Assessment: Unspecified disorder of the synovium and tendon in the right elbow (ICD-10 Code M67.931). Plan: Recommend physical therapy focusing on strengthening and flexibility exercises. Advise the patient on activity modifications to reduce strain on the elbow. Schedule a follow-up appointment in 6 weeks to assess progress.
Differential Diagnoses
When diagnosing conditions under M67.931, it is crucial to differentiate from other similar musculoskeletal disorders:
- Rotator Cuff Tear (M75.121) - Characterized by a complete or partial tear of the rotator cuff tendons.
- Shoulder Bursitis (M75.51) - Inflammation of the bursa leading to pain and restricted movement.
- Adhesive Capsulitis (M75.0) - Also known as frozen shoulder; marked by stiffness and pain in the joint capsule.
- Tendinitis (M76.1) - Inflammation of a tendon which may involve any tendon around the shoulder but not specifically categorized under M67.931.
Documentation Best Practices
Accurate documentation is essential for effective billing under ICD-10 code M67.931:
- Document all relevant clinical findings including history, physical exam results, imaging studies, and treatment plans.
- Ensure all diagnoses are clearly stated in your EMR system with appropriate coding linked to treatment provided.
- Use modifiers when necessary to indicate bilateral involvement or specific procedures performed.
Proper documentation supports medical necessity for treatments rendered and aids in avoiding claim denials.
