Shoulder lesions — ICD-10 M75.80
Shoulder lesions
Overview
Shoulder lesions encompass a variety of injuries and conditions affecting the shoulder joint, which can involve the muscles, tendons, ligaments, and cartilage. These lesions can result from acute trauma or chronic overuse, leading to pain, decreased range of motion, and functional limitations. The ICD-10 code M75.80 specifically refers to "Other specified shoulder lesions," which may include conditions such as rotator cuff tears, labral tears, and impingement syndromes that do not fall into more specific categories.
Understanding shoulder lesions is crucial for clinicians as they can significantly impact a patient's quality of life and ability to perform daily activities. This article will provide a comprehensive overview of shoulder lesions, including their anatomy, pathophysiology, clinical presentation, diagnostic methods, treatment strategies, and billing considerations.
The shoulder is one of the most mobile joints in the human body, composed of three primary bones: the humerus (upper arm bone), scapula (shoulder blade), and clavicle (collarbone). The shoulder joint is a ball-and-socket joint formed by the head of the humerus fitting into the glenoid cavity of the scapula. The stability of this joint is maintained by several key structures:
- Rotator Cuff: Comprising four muscles (supraspinatus, infraspinatus, teres minor, subscapularis) and their associated tendons, the rotator cuff stabilizes the humeral head during shoulder movements.
- Glenoid Labrum: A fibrocartilaginous structure that deepens the glenoid cavity, providing additional stability to the shoulder joint.
- Bursa: Fluid-filled sacs that reduce friction between moving structures in the shoulder.
The biomechanics of the shoulder allow for a wide range of motion in multiple planes—flexion, extension, abduction, adduction, internal rotation, and external rotation. However, this mobility comes at the cost of stability; thus, the shoulder is susceptible to various injuries and lesions.
Comman symptoms
The clinical presentation of shoulder lesions varies depending on severity:
Mild (Grade I)
- Symptoms: Mild pain with overhead activities; no significant loss of range of motion.
- Functionality: Patients may experience discomfort but can perform daily activities without major limitations.
Moderate (Grade II)
- Symptoms: Moderate pain at rest and during activity; noticeable weakness in affected arm; some limitation in range of motion.
- Functionality: Difficulty with overhead tasks; patients may require modifications in daily activities.
Severe (Grade III)
- Symptoms: Severe pain at rest; significant weakness; marked limitation in range of motion; possible swelling or visible deformity.
- Functionality: Patients are unable to perform most daily activities without assistance.
Red Flag
Clinicians should remain vigilant for red flags that warrant referral to a specialist:
- Persistent severe pain unresponsive to conservative measures
- Signs of infection (fever, chills)
- Neurological symptoms such as numbness or tingling in the arm
- Significant loss of function affecting daily living despite therapy

Causes & Risk Factors
Shoulder lesions can arise from several pathophysiological mechanisms. Common causes include:
- Acute Injury: Trauma from falls or sports activities can lead to tears in the rotator cuff or labrum.
- Chronic Overuse: Repetitive overhead activities (e.g., swimming, tennis) can cause microtrauma to the rotator cuff tendons or bursa inflammation.
- Aging: Degenerative changes in tendons and ligaments contribute to increased risk as individuals age.
Risk Factors
Several factors increase susceptibility to shoulder lesions:
- Age: Older adults are more prone to degenerative changes.
- Occupation: Jobs requiring repetitive overhead lifting or reaching can predispose individuals to injury.
- Sports Participation: Athletes engaged in throwing sports or overhead activities are at higher risk.
- Previous Injuries: A history of shoulder injuries increases the likelihood of re-injury.
Diagnostic Workup
A thorough diagnostic workup for shoulder lesions typically includes:
History Taking
Clinicians should obtain a detailed history regarding:
- Mechanism of injury
- Duration and nature of symptoms
- Previous treatments attempted
Physical Examination
Key components include:
- Inspection: Look for asymmetry, swelling, or muscle atrophy.
- Palpation: Assess tenderness over specific structures (e.g., rotator cuff tendons).
- Range of Motion Testing: Evaluate both active and passive range of motion.
- Strength Testing: Assess strength in flexion, extension, abduction, adduction, internal rotation, and external rotation.
Diagnostic Imaging
Imaging modalities may include:
- X-rays: To rule out fractures or dislocations.
- MRI: To evaluate soft tissue structures such as rotator cuff tears or labral injuries.
- Ultrasound: Useful for dynamic assessment of rotator cuff function.
Treatment & Rehabilitation
The rehabilitation process for shoulder lesions typically follows a structured four-phase protocol:
Phase 1: Acute Phase (0–2 weeks)
- Goals: Reduce pain and inflammation.
- Interventions:
- Rest and ice application
- Gentle range-of-motion exercises (pendulum swings)
Phase 2: Recovery Phase (2–6 weeks)
- Goals: Restore range of motion and begin strengthening.
- Interventions:
- Active-assisted range-of-motion exercises (e.g., wall climbs)
- Isometric strengthening exercises for rotator cuff muscles
Phase 3: Strengthening Phase (6–12 weeks)
- Goals: Improve strength and functional capacity.
- Interventions:
- Resistance band exercises (external/internal rotation)
- Scapular stabilization exercises
Phase 4: Return-to-Sport Phase (12+ weeks)
- Goals: Full return to activity/sport-specific training.
- Interventions:
- Plyometric exercises
- Sport-specific drills
Prevention
To prevent shoulder lesions, it is essential to incorporate evidence-based strategies that focus on ergonomics, lifestyle modifications, and risk management. Ergonomic assessments in the workplace can help identify and mitigate risk factors associated with repetitive shoulder movements, poor posture, and heavy lifting. Implementing proper lifting techniques and using assistive devices can further reduce strain on shoulder muscles and joints. Furthermore, engaging in regular strength training and flexibility exercises can enhance shoulder stability and resilience. Additionally, maintaining a healthy weight can alleviate excess stress on the shoulder joint. Regular breaks during repetitive tasks and promoting awareness of body mechanics can also contribute to the prevention of shoulder lesions and their recurrence.
Coding Examples
Patient presents with a 45-year-old male who reports persistent pain in his right shoulder following a recent sports injury. Upon examination, the physician notes tenderness and limited range of motion in the shoulder joint. Code as M75.80 because the documentation indicates a shoulder lesion without a specific diagnosis, fitting the criteria for unspecified shoulder lesions as per ICD-10-CM guidelines.
Audit & Compliance
To support medical necessity and prevent claim denials for ICD-10 code M75.80, healthcare providers must ensure thorough documentation that includes:
- A detailed history of present illness outlining the onset, duration, and characteristics of the shoulder pain.
- Results of physical examinations and any relevant imaging studies that substantiate the diagnosis of a shoulder lesion.
- Clear documentation of treatment plans and the rationale for chosen interventions.
- Evidence of patient education regarding preventive strategies and follow-up care.
- Any comorbid conditions that may contribute to the shoulder lesion should also be documented for a comprehensive understanding of the patient's health status.
Clinical Example
Subjective: A 60-year-old female patient reports a 3-month history of right shoulder pain, which worsens with overhead activities. She denies any history of trauma but has a sedentary job that requires prolonged computer use. Objective: On physical examination, the right shoulder displays limited range of motion, particularly in abduction and external rotation. Tenderness is noted over the rotator cuff area. Special tests (Neer and Hawkins) are positive for impingement. Assessment: Right shoulder lesion, likely due to rotator cuff impingement syndrome without a specified diagnosis (ICD-10 code M75.80). Plan: The patient will undergo conservative management, including physical therapy focusing on strengthening and flexibility exercises, NSAIDs for pain control, and ergonomic recommendations for her workstation. A follow-up appointment is scheduled for 6 weeks to reassess symptoms.
Differential Diagnoses
When diagnosing shoulder lesions using ICD-10 codes, clinicians must consider several differential diagnoses:
- Rotator Cuff Tear (M75.11) – Partial or complete tear of one or more rotator cuff tendons.
- Shoulder Impingement Syndrome (M75.40) – Compression of rotator cuff tendons under the acromion during arm elevation.
- Labral Tear (M75.12) – Injury to the glenoid labrum affecting stability and function.
- Adhesive Capsulitis (Frozen Shoulder) (M75.0) – Characterized by stiffness and pain in the shoulder joint due to inflammation and fibrosis.
Documentation Best Practices
Accurate documentation is essential for billing purposes under ICD-10 code M75.80. Key elements include:
- Detailed patient history including mechanism of injury.
- Comprehensive physical examination findings documenting range of motion and strength deficits.
- Results from imaging studies supporting diagnosis.
- Treatment plans outlining rehabilitation protocols.
Proper coding ensures appropriate reimbursement for services rendered while maintaining compliance with insurance requirements.
