Shoulder lesions — ICD-10 M75.5
Shoulder lesions
Overview
Shoulder lesions, classified under ICD-10 code M75.5, encompass a variety of injuries and conditions affecting the soft tissues and structures around the shoulder joint. These lesions can involve the muscles, tendons, ligaments, and cartilage that contribute to the shoulder's complex functionality. Clinically, shoulder lesions are often associated with pain, reduced range of motion, and functional impairment, significantly impacting daily activities and quality of life.
Shoulder lesions can arise from acute injuries or chronic overuse, making them prevalent among athletes and individuals engaged in repetitive overhead activities. Understanding the underlying anatomy, biomechanics, and pathophysiology is crucial for accurate diagnosis and effective management.
The shoulder joint consists of several key anatomical structures:
- Glenohumeral Joint: This ball-and-socket joint allows for a wide range of motion but is inherently unstable due to its shallow socket.
- Rotator Cuff: Comprising four muscles (supraspinatus, infraspinatus, teres minor, subscapularis), the rotator cuff stabilizes the humeral head within the glenoid cavity.
- Biceps Tendon: The long head of the biceps tendon also plays a role in shoulder stability and movement.
- Labrum: A fibrocartilaginous structure that deepens the glenoid cavity, providing additional stability to the shoulder joint.
Biomechanically, the shoulder joint's design allows for significant mobility at the expense of stability. This unique arrangement makes it susceptible to injuries such as tears, impingement syndromes, and tendinopathies. The rotator cuff muscles work synergistically to facilitate shoulder movements while maintaining joint congruence.
Comman symptoms
The clinical presentation of shoulder lesions varies based on severity:
Mild (Grade I)
- Symptoms: Mild pain during specific activities; no significant loss of range of motion.
- Functional Impact: Minimal; patients may continue normal activities with slight discomfort.
Moderate (Grade II)
- Symptoms: Increased pain at rest and during activity; noticeable weakness; limited range of motion.
- Functional Impact: Difficulty with overhead activities; patients may require modifications in daily tasks.
Severe (Grade III)
- Symptoms: Severe pain; significant loss of function; possible audible pop or snap during injury; marked weakness.
- Functional Impact: Inability to perform normal activities; potential need for surgical intervention.
Red Flag
Clinicians should be vigilant for red flags that warrant referral to a specialist:
- Persistent pain despite conservative treatment beyond six weeks.
- Significant weakness or atrophy in the shoulder musculature.
- Signs of systemic illness (fever, night sweats).
- Acute traumatic injury with possible fracture or dislocation.
Referral to an orthopedic surgeon may be necessary for surgical evaluation or advanced imaging.

Causes & Risk Factors
Shoulder lesions can result from various pathophysiological processes:
- Acute Injuries: Sudden trauma can lead to tears in the rotator cuff or biceps tendon. Common mechanisms include falls or lifting heavy objects.
- Chronic Overuse: Repetitive overhead activities can cause microtrauma to the rotator cuff tendons, leading to tendinopathy or tears. This is common in athletes involved in sports like swimming, baseball, or tennis.
Risk Factors
Several factors may predispose individuals to shoulder lesions:
- Age: Degenerative changes in tendon structure are more common in older adults.
- Activity Level: Athletes or individuals with occupations requiring repetitive overhead motions are at higher risk.
- Previous Injuries: A history of shoulder injuries increases susceptibility to future lesions.
- Posture: Poor scapular positioning can lead to abnormal shoulder mechanics and increased stress on tendons.
Diagnostic Workup
A thorough diagnostic workup is essential for identifying shoulder lesions:
History
A detailed patient history should include:
- Mechanism of injury (acute vs. chronic)
- Duration and nature of symptoms
- Previous shoulder injuries or surgeries
- Functional limitations
Physical Examination
Key components include:
- Inspection: Look for swelling, deformity, or atrophy.
- Palpation: Assess tenderness over the rotator cuff tendons and biceps tendon.
- Range of Motion Testing: Evaluate both active and passive range of motion.
- Strength Testing: Assess strength in abduction, external rotation, and internal rotation.
Imaging Studies
- X-rays: To rule out fractures or osteoarthritis.
- MRI: The gold standard for soft tissue evaluation; identifies rotator cuff tears and other lesions.
- Ultrasound: Useful for dynamic assessment of rotator cuff function.
Treatment & Rehabilitation
Treatment for shoulder lesions typically involves a combination of conservative management and rehabilitation exercises structured into four phases:
Phase 1: Acute Management (Weeks 1-2)
- Goals: Reduce pain and inflammation.
- Interventions:
- Rest and activity modification
- Ice application
- Non-steroidal anti-inflammatory drugs (NSAIDs)
Phase 2: Range of Motion Restoration (Weeks 3-4)
- Goals: Restore passive range of motion.
- Exercises:
- Pendulum swings
- Assisted flexion and abduction
- Internal/external rotation with a towel
Phase 3: Strengthening (Weeks 5-8)
- Goals: Improve muscle strength and stability.
- Exercises:
- Isometric exercises for rotator cuff muscles
- Resistance band external rotation
- Scapular stabilization exercises
Phase 4: Functional Training (Weeks 9+)
- Goals: Return to sport or activity-specific tasks.
- Exercises:
- Plyometric exercises (e.g., medicine ball toss)
- Overhead press with light weights
- Sport-specific drills
Each phase should be tailored to individual progress and symptomatology.
Prevention
To effectively prevent shoulder lesions (ICD-10 Code M75.5) or their recurrence, evidence-based strategies should focus on ergonomics, lifestyle modifications, and risk management.
- Ergonomics: Ensure proper workplace ergonomics by maintaining a neutral shoulder position during activities. Use adjustable chairs and workstations, and position computer screens at eye level to minimize strain.
- Exercise and Strength Training: Incorporate regular shoulder-strengthening exercises and flexibility training into your routine. Activities such as rotator cuff exercises and scapular stabilization can enhance shoulder joint stability.
- Posture Awareness: Educate individuals on the importance of maintaining good posture. Encourage sitting and standing with shoulders back and down, which helps reduce undue stress on shoulder structures.
- Activity Modification: Identify and modify activities that may exacerbate shoulder strain, such as repetitive overhead lifting or prolonged arm positioning. Use assistive devices when necessary.
- Regular Breaks: Implement scheduled breaks during repetitive tasks to allow the shoulder muscles to recover and reduce fatigue.
Coding Examples
Patient presents with right shoulder pain that has persisted for six months, accompanied by limited range of motion and tenderness upon palpation. After a thorough examination and diagnostic imaging, a diagnosis of rotator cuff tear is made. Code as M75.5 because this code encompasses shoulder lesions, including rotator cuff tears, which are documented as the primary diagnosis.
Audit & Compliance
To support medical necessity and prevent claim denials for ICD-10 Code M75.5, the following documentation elements are essential:
- Detailed History: Document the onset, duration, and characteristics of shoulder symptoms to establish a clear clinical picture.
- Physical Examination Findings: Include specific findings from the physical examination, such as range of motion measurements, tenderness locations, and results of special tests.
- Diagnostic Imaging Reports: Ensure that any imaging studies (e.g., MRI, X-rays) are documented and clearly linked to the diagnosis of shoulder lesions.
- Treatment Plan: Outline the proposed treatment plan, including conservative measures attempted and the rationale for any further interventions.
- Follow-Up Documentation: Record any follow-up visits, patient responses to treatments, and adjustments made to the treatment plan based on patient progress.
Clinical Example
Subjective: A 54-year-old female patient presents with complaints of persistent pain in her right shoulder for the past four months, stating that it worsens with overhead activities and during sleep. She reports no history of trauma. Objective: Physical examination reveals tenderness to palpation over the greater tuberosity of the humerus and positive Neer and Hawkins-Kennedy tests. Range of motion is limited, especially in abduction and external rotation. MRI results indicate a partial thickness tear of the supraspinatus tendon. Assessment: Right shoulder lesion (ICD-10 Code M75.5) due to a partial thickness tear of the rotator cuff. Plan: Initiate a conservative treatment plan including physical therapy focused on strengthening and stretching exercises. Consider a follow-up visit in six weeks to assess progress, with the option for corticosteroid injection if symptoms persist.
Differential Diagnoses
Several conditions may mimic shoulder lesions:
- Rotator Cuff Tear (M75.1): Complete or partial tear involving rotator cuff tendons.
- Shoulder Impingement Syndrome (M75.4): Compression of rotator cuff tendons beneath the acromion leading to pain and dysfunction.
- Biceps Tendon Rupture (M75.2): Injury to the long head of the biceps tendon presenting with specific symptoms.
- Frozen Shoulder (Adhesive Capsulitis) (M75.0): Characterized by stiffness and pain due to inflammation of the shoulder capsule.
Differentiating these conditions is critical for appropriate management.
Documentation Best Practices
Accurate documentation is essential for billing purposes under ICD-10 code M75.5:
- Clearly document patient history, physical examination findings, imaging results, and treatment plans.
- Use specific codes for differential diagnoses when applicable (e.g., M75.1 for rotator cuff tear).
- Ensure that all services provided are documented in accordance with payer guidelines to facilitate reimbursement.
Proper coding not only aids in billing but also supports continuity of care through comprehensive medical records.
