Shoulder lesions — ICD-10 M75.100
Shoulder lesions
Overview
Shoulder lesions refer to a variety of injuries or degenerative changes affecting the structures of the shoulder joint, including the muscles, tendons, ligaments, and cartilage. These lesions can lead to pain, reduced range of motion, and functional impairment. The ICD-10 code M75.100 specifically denotes unspecified shoulder lesions, which may encompass conditions such as rotator cuff tears, labral tears, or impingement syndrome.
Shoulder lesions are prevalent among athletes and individuals engaged in repetitive overhead activities, but they can also occur due to acute trauma or degenerative processes associated with aging. Understanding the complexities of shoulder anatomy and biomechanics is crucial for effective diagnosis and treatment.
The shoulder joint is one of the most mobile joints in the human body, comprising several components:
- Glenohumeral Joint: The primary ball-and-socket joint formed by the head of the humerus and the glenoid cavity of the scapula.
- Rotator Cuff: A group of four muscles (supraspinatus, infraspinatus, teres minor, subscapularis) that stabilize the shoulder and allow for movement.
- Labrum: A fibrocartilaginous structure that deepens the glenoid cavity and provides stability.
- Bursa: Fluid-filled sacs that reduce friction between moving parts, particularly between the rotator cuff tendons and the acromion.
The biomechanics of the shoulder involve a complex interplay between these structures during various movements, such as reaching overhead or lifting objects. The shoulder's extensive range of motion makes it susceptible to injuries, especially during high-demand activities.
Comman symptoms
Symptoms of shoulder lesions can vary based on severity:
Mild Lesions
- Symptoms: Mild pain during overhead activities, slight tenderness over the shoulder.
- Functional Limitations: Minimal impact on daily activities.
Moderate Lesions
- Symptoms: Persistent pain at rest or during activity, increased tenderness, swelling.
- Functional Limitations: Difficulty with overhead movements; potential weakness in arm.
Severe Lesions
- Symptoms: Severe pain, significant swelling, possible visible deformity, loss of range of motion.
- Functional Limitations: Inability to perform daily activities; may require assistance.
Red Flag
Clinicians should be vigilant for red flags indicating the need for further evaluation:
- Persistent severe pain unresponsive to conservative management.
- Signs of systemic illness (fever, weight loss).
- Neurological symptoms (numbness or weakness in the arm).
- Significant loss of range of motion after initial treatment.
Referral to an orthopedic specialist may be warranted for advanced imaging or surgical evaluation in these cases.

Causes & Risk Factors
Shoulder lesions can arise from various mechanisms:
- Acute Trauma: Falls or direct blows can result in tears or fractures.
- Chronic Overuse: Repetitive overhead motions can cause microtrauma leading to tendonitis or impingement.
- Degenerative Changes: Age-related wear and tear can lead to rotator cuff degeneration or labral tears.
Risk Factors
- Age: Older adults are at increased risk due to degenerative changes.
- Occupation: Jobs requiring repetitive overhead work (e.g., painters, athletes) increase susceptibility.
- Previous Injuries: History of shoulder injuries predisposes individuals to future lesions.
- Poor Posture: Improper alignment can lead to abnormal stresses on shoulder structures.
Diagnostic Workup
A thorough clinical examination is essential for diagnosing shoulder lesions:
History Taking
- Assess onset, duration, and nature of symptoms.
- Inquire about previous injuries or surgeries.
Physical Examination
- Inspection: Look for swelling, bruising, or deformities.
- Palpation: Identify areas of tenderness around the rotator cuff and bursa.
- Range of Motion (ROM): Evaluate both active and passive ROM.
- Strength Testing: Assess muscle strength in various planes of motion.
Diagnostic Imaging
- X-rays: Useful for identifying fractures or dislocations.
- MRI: Provides detailed images of soft tissue structures; essential for assessing rotator cuff tears or labral injuries.
- Ultrasound: Can be used for dynamic assessment of rotator cuff function.
Treatment & Rehabilitation
Effective treatment for shoulder lesions typically follows a structured rehabilitation protocol divided into four phases:
Phase 1: Acute Phase (0-2 weeks)
- Goals: Reduce pain and inflammation.
- Interventions:
- Rest and ice application.
- Non-steroidal anti-inflammatory drugs (NSAIDs).
- Gentle range-of-motion exercises (e.g., pendulum swings).
Phase 2: Recovery Phase (2-6 weeks)
- Goals: Restore range of motion and begin strengthening.
- Interventions:
- Continue gentle stretching exercises (e.g., wall crawls).
- Begin isometric strengthening exercises (e.g., internal/external rotation).
Phase 3: Strengthening Phase (6-12 weeks)
- Goals: Increase strength and stability.
- Interventions:
- Progressive resistance training (e.g., theraband exercises).
- Functional exercises (e.g., overhead presses).
Phase 4: Return to Activity Phase (12+ weeks)
- Goals: Achieve full functional capacity.
- Interventions:
- Sport-specific drills for athletes (e.g., throwing mechanics).
- Advanced proprioceptive training (e.g., balance exercises).
Regular reassessment should guide progression through these phases based on individual recovery rates.
Prevention
Preventing shoulder lesions, particularly those classified under ICD-10 code M75.100, involves a multifaceted approach focusing on ergonomics, lifestyle modifications, and risk management. Evidence-based strategies include:
- Ergonomic Adjustments: Ensure that workstations are designed to promote shoulder health. This can involve adjusting the height of desks, using chairs that provide proper back support, and encouraging frequent breaks to reduce prolonged shoulder strain.
- Strengthening Exercises: Incorporating specific shoulder-strengthening exercises into daily routines can help fortify the muscles around the shoulder joint. Resistance training targeting the rotator cuff can be particularly beneficial.
- Proper Lifting Techniques: Educating individuals on safe lifting techniques, such as keeping the load close to the body and using the legs instead of the back or shoulders, can significantly reduce the risk of injury.
- Weight Management: Maintaining a healthy weight can lessen the burden on joints, including the shoulders, thus lowering the risk of lesions.
- Regular Stretching: Implementing a routine of shoulder stretches can improve flexibility and decrease tension in the shoulder muscles, potentially preventing injuries.
Coding Examples
Patient presents with a 45-year-old female experiencing persistent left shoulder pain and decreased range of motion following a fall while gardening. Upon examination, there is tenderness, and imaging reveals a rotator cuff tear. Code as M75.100 because this code specifically captures the diagnosis of a shoulder lesion, which encompasses injuries such as rotator cuff tears, aligning with the clinical findings and imaging results.
Audit & Compliance
To ensure compliance and support medical necessity for ICD-10 code M75.100, the following documentation elements must be included:
- Detailed Patient History: Document any previous shoulder injuries, chronic conditions, and the onset of symptoms.
- Physical Examination Findings: Record specific objective findings, including range of motion, strength testing, and any special tests performed.
- Diagnostic Imaging Results: Include results from any imaging studies that confirm the presence of a shoulder lesion, such as MRI or ultrasound findings.
- Treatment Plan: Clearly outline the proposed treatment plan, including any referrals to physical therapy or specialists, and the rationale for these decisions.
- Follow-Up Plans: Document plans for follow-up assessments to evaluate the effectiveness of treatment and any adjustments needed.
Clinical Example
Subjective: A 62-year-old male reports a 3-month history of right shoulder pain that worsens with overhead activities. He denies any specific injury but mentions a history of repetitive lifting at work. Objective: Physical examination reveals limited range of motion in the right shoulder, tenderness over the rotator cuff area, and positive impingement signs. An MRI shows a partial thickness tear of the supraspinatus tendon. Assessment: Right shoulder lesion characterized by a partial tear of the supraspinatus tendon, consistent with ICD-10 code M75.100. Plan: Recommend physical therapy focusing on rotator cuff strengthening and flexibility. A follow-up appointment is scheduled in 6 weeks to assess progress. Consider corticosteroid injection if symptoms do not improve.
Differential Diagnoses
When evaluating shoulder lesions, it is crucial to consider other potential diagnoses:
- Rotator Cuff Tear (M75.101) - Complete or partial tear of rotator cuff tendons.
- Shoulder Impingement Syndrome (M75.110) - Compression of rotator cuff tendons under the acromion.
- Labral Tear (M75.102) - Injury to the glenoid labrum affecting stability.
- Bursitis (M70.0) - Inflammation of the subacromial bursa causing pain.
Differentiating these conditions is vital for appropriate management and coding.
Documentation Best Practices
Accurate documentation is critical for billing purposes under ICD-10 code M75.100:
- Clearly document patient history, physical examination findings, and diagnostic imaging results.
- Include specific details regarding functional limitations and impact on daily activities.
- Ensure that all treatments provided are documented alongside corresponding CPT codes for services rendered.
Proper coding will facilitate reimbursement while ensuring compliance with regulatory standards.
