Musculoskeletal condition M71.50 — ICD-10 M71.50
Musculoskeletal condition M71.50
Overview
ICD-10 code M71.50 refers to "Bursitis, unspecified, site unspecified." Bursitis is an inflammatory condition affecting the bursa, a small fluid-filled sac that acts as a cushion between bones and soft tissues such as muscles, tendons, and skin. Bursae are found throughout the body, particularly in joints, and serve to reduce friction during movement. While bursitis can occur in various locations, the unspecified nature of M71.50 indicates that the exact site of the inflammation has not been determined or documented.
Bursitis can arise from acute trauma, chronic overuse, or underlying systemic conditions. Understanding this condition is essential for clinicians, rehabilitation providers, and patients alike, as it plays a significant role in musculoskeletal health and function.
Bursae are synovial-lined sacs located throughout the body, particularly in areas where friction occurs between moving structures. Key anatomical sites for bursae include:
- Shoulder: Subacromial bursa
- Elbow: Olecranon bursa
- Hip: Greater trochanteric bursa
- Knee: Prepatellar bursa (housemaid's knee) and infrapatellar bursa
- Achilles tendon: Retrocalcaneal bursa
The primary function of these bursae is to facilitate smooth movement and reduce friction between bones and surrounding soft tissues. Biomechanically, when a joint is subjected to repetitive motion or excessive load, the bursa can become inflamed due to increased friction or direct trauma. This inflammation can lead to pain and functional impairment.
Comman symptoms
Symptoms of bursitis can vary based on severity:
Mild Bursitis
- Localized tenderness at the site of inflammation
- Mild swelling
- Pain during specific movements but not at rest
Moderate Bursitis
- Increased swelling and warmth over the affected area
- Pain that may radiate to nearby structures
- Difficulty with joint movement; pain during daily activities
Severe Bursitis
- Significant swelling and redness
- Severe pain that limits mobility
- Possible fever if infection is present (indicative of septic bursitis)
Patients may also report a sensation of stiffness in the affected joint upon waking or after prolonged periods of inactivity.
Red Flag
Clinicians should be vigilant for red flags indicating potential complications:
- Severe pain unresponsive to medication.
- Persistent swelling despite conservative management.
- Signs of infection (fever, chills).
- Neurological symptoms (numbness or weakness).
Referral to an orthopedic specialist may be warranted if these signs are present or if there is no improvement after six weeks of conservative treatment.

This inflammation can lead to pain and functional impairment.
Causes & Risk Factors
Bursitis typically results from one of several underlying mechanisms:
- Overuse Injuries: Repetitive motions can irritate the bursa, leading to inflammation.
- Trauma: Direct impact or injury can cause acute bursitis.
- Infection: Septic bursitis occurs when bacteria infect the bursa.
- Systemic Conditions: Diseases such as rheumatoid arthritis or gout can contribute to bursitis.
Risk Factors
- Age: Older adults are more susceptible due to degenerative changes.
- Occupational Hazards: Jobs involving repetitive motions (e.g., painting, carpentry) increase risk.
- Sports Participation: Athletes engaged in high-impact sports may experience higher rates of bursitis.
- Obesity: Increased body weight can place additional stress on joints.
- Pre-existing Conditions: Individuals with inflammatory diseases or prior joint injuries are at greater risk.
Diagnostic Workup
A thorough clinical evaluation is essential for diagnosing bursitis:
History Taking
Clinicians should gather information about:
- Onset of symptoms
- Activities contributing to symptoms
- Previous injuries or conditions affecting the area
Physical Examination
Key components include:
- Inspection for swelling, redness, or warmth over the bursa.
- Palpation to assess tenderness and range of motion.
- Functional testing to evaluate joint stability and mobility.
Imaging Studies
While imaging is often not necessary for diagnosis, it may be used in complex cases:
- X-rays: To rule out fractures or bone spurs.
- Ultrasound: To visualize fluid accumulation within the bursa.
- MRI: For detailed imaging in chronic cases or when associated with other pathologies.
Treatment & Rehabilitation
The treatment of bursitis typically involves a combination of conservative management strategies followed by rehabilitation exercises:
Phase 1: Acute Management (0–2 weeks)
Goals:
- Reduce inflammation and pain.
Interventions:
- Rest and activity modification.
- Ice application for 15–20 minutes several times a day.
- Nonsteroidal anti-inflammatory drugs (NSAIDs) for pain relief.
Phase 2: Early Rehabilitation (2–4 weeks)
Goals:
- Gradual reintroduction of movement.
Exercises:
- Range of Motion Exercises:
- Pendulum swings for shoulder bursitis.
- Gentle knee flexion/extension for knee bursitis.
Phase 3: Strengthening Phase (4–6 weeks)
Goals:
- Restore strength and stability.
Exercises:
- Isometric Strengthening:
- Isometric shoulder abduction against resistance.
- Straight leg raises for hip bursitis.
Phase 4: Functional Training (6+ weeks)
Goals:
- Return to full function and prevent recurrence.
Exercises:
- Dynamic Strengthening:
- Resistance band exercises for shoulder stabilization.
- Step-ups and lateral lunges for hip stability.
Prevention
To prevent musculoskeletal conditions such as those classified under ICD-10 code M71.50, evidence-based strategies should be implemented focusing on ergonomics, lifestyle modifications, and risk management. Ergonomic interventions in the workplace, such as adjusting chair heights and using proper lifting techniques, can significantly reduce strain on muscles and joints. Lifestyle changes, including regular physical activity, maintaining a healthy weight, and practicing good posture, can improve musculoskeletal health. Additionally, risk management strategies, such as regular health screenings and employee training on injury prevention, are essential in mitigating risk factors associated with musculoskeletal disorders.
Coding Examples
Patient presents with complaints of pain and swelling in the right knee. Upon examination, the physician notes inflammation in the joint without any specified underlying condition. Code as M71.50 because this code indicates a localized musculoskeletal condition characterized by unspecified inflammation in the soft tissue surrounding the joint, which aligns with the patient's symptoms and clinical findings.
Audit & Compliance
To support medical necessity and prevent claim denials for ICD-10 code M71.50, the following key documentation elements are essential:
- A clear diagnosis indicating the presence of localized inflammation of soft tissues.
- Detailed clinical findings supporting the diagnosis, including the patient's symptoms and physical examination results.
- An explicit treatment plan that outlines the recommended interventions, including medications, therapies, and follow-up care.
- Documentation of patient history, including any relevant risk factors or previous musculoskeletal issues that may contribute to the current condition.
Clinical Example
Subjective: A 52-year-old female patient reports persistent pain in her left shoulder, describing it as a dull ache that worsens with overhead activities. She denies any recent trauma or prior history of shoulder issues. Objective: Physical examination reveals tenderness over the left shoulder joint, decreased range of motion, and mild swelling. No signs of acute injury are noted. Assessment: The patient is diagnosed with unspecified localized inflammation of the soft tissue surrounding the shoulder joint, consistent with ICD-10 code M71.50. Plan: The treatment plan includes recommending physical therapy focused on range-of-motion exercises, prescribing non-steroidal anti-inflammatory drugs (NSAIDs) for pain management, and scheduling a follow-up appointment in four weeks to assess improvement.
Differential Diagnoses
When diagnosing bursitis, it is crucial to differentiate it from other conditions that may present similarly:
- Tendinitis (M75.1): Inflammation of tendons around joints.
- Arthritis (M15-M19): Inflammatory joint diseases such as osteoarthritis or rheumatoid arthritis.
- Synovitis (M65): Inflammation of the synovial membrane.
- Soft Tissue Tumors (M72): Masses that may mimic bursitis symptoms.
Accurate coding is essential for proper management and billing.
Documentation Best Practices
Accurate documentation is critical for reimbursement purposes:
- Ensure clear documentation of symptoms, physical exam findings, and any imaging studies performed.
- Use specific ICD codes based on the location if known; otherwise, M71.50 should be used appropriately.
- Include details regarding treatment plans and patient progress in EMR systems for optimal billing outcomes.
