Shoulder lesions — ICD-10 M75.10
Shoulder lesions
Overview
Shoulder lesions encompass a variety of injuries and pathologies affecting the structures around the shoulder joint, including tendons, ligaments, cartilage, and the joint capsule. The ICD-10 code M75.10 specifically refers to unspecified shoulder lesions, which can present in various forms, including rotator cuff tears, labral tears, and impingement syndromes. The shoulder is a highly mobile joint that allows for a wide range of motion; however, this mobility also predisposes it to injuries.
Understanding shoulder lesions is crucial for clinicians, as they can significantly impact a patient’s quality of life and functional ability. This article aims to provide an in-depth analysis of shoulder lesions, focusing on their anatomy, pathophysiology, symptoms, diagnosis, treatment protocols, and documentation practices.
The shoulder complex consists of several key anatomical structures:
- Glenohumeral Joint: The ball-and-socket joint formed by the head of the humerus and the glenoid cavity of the scapula.
- Rotator Cuff: Comprising four muscles (supraspinatus, infraspinatus, teres minor, and subscapularis), the rotator cuff stabilizes the glenohumeral joint and facilitates arm movement.
- Labrum: A fibrocartilaginous structure that deepens the glenoid cavity and provides stability to the shoulder.
- Bursa: Fluid-filled sacs that reduce friction between moving parts in the shoulder.
Biomechanically, the shoulder allows for flexion, extension, abduction, adduction, internal rotation, and external rotation. The intricate interplay between muscles and tendons during these movements makes the shoulder susceptible to injuries from overuse or acute trauma.
Comman symptoms
Stage 1: Mild Lesions
Patients may experience mild pain localized to the shoulder with no significant loss of function. Symptoms may include:
- Mild discomfort during overhead activities
- Occasional stiffness
Stage 2: Moderate Lesions
As lesions progress, symptoms become more pronounced:
- Persistent pain during daily activities
- Limited range of motion
- Pain at night that interferes with sleep
Stage 3: Severe Lesions
In advanced cases, patients may present with:
- Severe pain that limits all shoulder movements
- Significant weakness in arm elevation
- Possible swelling or visible deformity if dislocation occurs
Red Flag
Clinicians should remain vigilant for red flags that may indicate a need for further evaluation or referral:
- Persistent Night Pain: Suggestive of possible serious underlying pathology.
- Significant Weakness: Indicating potential nerve involvement or complete tears.
- Acute Swelling or Deformity: May suggest fracture or dislocation requiring immediate care.
- Failure to Improve After Conservative Treatment: Consider imaging studies or referral to an orthopedic specialist.

Causes & Risk Factors
Shoulder lesions can arise from various mechanisms:
- Overuse: Repetitive overhead activities can lead to microtrauma in the rotator cuff tendons or labrum.
- Acute Injury: Falls or direct impacts can cause tears or dislocations.
- Degeneration: Age-related changes can weaken tendons and ligaments.
Risk Factors
- Age: Older individuals are at higher risk due to degenerative changes.
- Activity Level: Athletes or individuals engaged in repetitive overhead activities (e.g., swimmers, throwers) are more susceptible.
- Previous Injuries: A history of shoulder injuries increases the likelihood of future lesions.
Diagnostic Workup
A thorough clinical examination is essential for diagnosing shoulder lesions. Key components include:
History Taking
- Detailed account of symptoms (onset, duration, aggravating factors)
- Previous medical history related to shoulder injuries
Physical Examination
- Inspection: Look for asymmetry or swelling.
- Palpation: Assess tenderness over specific structures like the rotator cuff or biceps tendon.
- Range of Motion Tests: Evaluate active and passive ROM to identify restrictions.
- Strength Testing: Assess muscle strength against resistance.
Imaging Studies
- X-rays: Useful for ruling out fractures or dislocations.
- MRI: Gold standard for visualizing soft tissue injuries including rotator cuff tears and labral injuries.
- Ultrasound: Can be used for dynamic assessment of rotator cuff function.
Treatment & Rehabilitation
The treatment approach for shoulder lesions typically involves a combination of conservative management and rehabilitation exercises tailored to each phase of recovery.
Phase 1: Acute Phase (0-2 weeks)
Goals: Reduce pain and inflammation. Interventions:
- Rest and ice application
- Non-steroidal anti-inflammatory drugs (NSAIDs)
Exercises:
- Pendulum swings
- Passive range-of-motion exercises within pain tolerance.
Phase 2: Subacute Phase (2-6 weeks)
Goals: Restore range of motion and begin strengthening. Interventions:
- Gradual increase in activity levels
- Physical therapy referral for guided rehabilitation
Exercises:
- Active-assisted range-of-motion exercises (e.g., wall climbing)
- Isometric strengthening exercises for rotator cuff muscles.
Phase 3: Strengthening Phase (6 weeks - 3 months)
Goals: Improve strength and functional capacity.
Exercises:
- Resistance band exercises targeting rotator cuff muscles (external/internal rotation)
- Scapular stabilization exercises (e.g., scapular retraction).
Phase 4: Functional Phase (3 months onward)
Goals: Return to sport/work activities without limitations.
Exercises:
- Sport-specific drills incorporating overhead movements
- Plyometric exercises if applicable.
Prevention
Preventing shoulder lesions, particularly those associated with overuse or strain, involves a multi-faceted approach that incorporates ergonomic adjustments, lifestyle modifications, and proactive risk management strategies. Key evidence-based strategies include:
- Ergonomics: Encourage proper posture when sitting, standing, or performing repetitive tasks to minimize shoulder strain. Utilize ergonomic tools such as adjustable chairs, desks, and keyboard placements.
- Exercise and Strengthening: Promote a regular routine of shoulder-strengthening and flexibility exercises. Focus on rotator cuff and scapular stabilizer muscle groups to enhance shoulder stability and function.
- Education and Awareness: Provide education on the importance of warm-up exercises before engaging in physical activities and the need for breaks during repetitive tasks to reduce the risk of overuse injuries.
- Weight Management: Encourage maintaining a healthy weight to reduce the mechanical load on the shoulder joints, thereby minimizing the risk of injury.
- Risk Management: Identify high-risk activities (e.g., heavy lifting, overhead work) and implement strategies to mitigate risks, such as using assistive devices or modifying techniques.
Coding Examples
Patient presents with limited range of motion in the left shoulder due to a chronic rotator cuff tear. The physician documents the condition in the medical record as a shoulder lesion. Code as M75.10 because it accurately reflects the diagnosis of unspecified shoulder lesion without further specified conditions. This code is appropriate when precise details about the type or cause of the lesion are not provided, aligning with ICD-10-CM guidelines.
Audit & Compliance
To support medical necessity and prevent claim denials for the ICD-10 code M75.10, the following key documentation elements should be included in the medical record:
- Thorough History: Document the patient's history of symptoms, including onset, duration, and any aggravating factors.
- Physical Examination Findings: Clearly detail the physical examination results, including range of motion, tenderness, and any specific tests performed that support the diagnosis.
- Diagnostic Imaging Reports: If applicable, include any imaging studies (e.g., X-rays, MRIs) that confirm the presence of a shoulder lesion or exclude other diagnoses.
- Treatment Plan: Outline the proposed treatment plan, including referrals to physical therapy or other specialists, to demonstrate a comprehensive approach to managing the condition.
- Follow-Up Documentation: Record follow-up visits and any changes in the patient's condition, treatment response, or additional interventions.
Clinical Example
Subjective: A 55-year-old female presents with complaints of persistent pain in her right shoulder, particularly when reaching overhead or lifting objects. She reports that the pain has gradually worsened over the past six months. Objective: On examination, there is tenderness to palpation over the anterior shoulder. The range of motion is limited, with pain noted during abduction and external rotation. No visible swelling or deformity is present. Assessment: Right shoulder lesion, unspecified (M75.10). Differential diagnosis includes rotator cuff tear or impingement syndrome. Plan: Recommend physical therapy focusing on strengthening exercises and range of motion activities. Prescribe NSAIDs for pain management. Follow up in 4-6 weeks to reassess shoulder function and pain levels.
Differential Diagnoses
When evaluating shoulder lesions (M75.10), clinicians should consider other potential diagnoses:
- Rotator Cuff Tear (M75.121): Full-thickness tear of rotator cuff.
- Shoulder Impingement Syndrome (M75.40): Compression of rotator cuff tendons.
- Shoulder Bursitis (M75.51): Inflammation of the subacromial bursa.
- Labral Tear (M75.12): Injury to the glenoid labrum.
- Adhesive Capsulitis (M75.0): Also known as frozen shoulder.
Documentation Best Practices
Accurate documentation is vital for billing purposes under ICD-10 code M75.10:
- Ensure detailed descriptions of patient history, physical examination findings, imaging results, treatment plans, and progress notes are included in EMR documentation.
- Use specific codes when applicable; e.g., if a rotator cuff tear is diagnosed later on, update records accordingly to M75.121.
- Document patient education regarding home exercise programs as well as any referrals made.
