Musculoskeletal condition M96.842 — ICD-10 M96.842
Musculoskeletal condition M96.842
Overview
M96.842 refers to "Post-surgical scar tissue affecting the musculoskeletal system." This condition arises after surgical interventions, particularly orthopedic procedures, where scar tissue (also known as adhesions) forms around muscles, tendons, ligaments, and joints. Such scar tissue can lead to pain, stiffness, and functional limitations, significantly impacting a patient's quality of life. Understanding this condition is crucial for clinicians involved in rehabilitation and recovery following surgery.
Anatomy
The musculoskeletal system comprises bones, muscles, tendons, ligaments, and fascia that provide structure and support to the body. Key components include:
- Muscles: Responsible for movement and stability.
- Tendons: Connect muscles to bones, facilitating joint movement.
- Ligaments: Connect bones to other bones at joints, providing stability.
- Fascia: A connective tissue that surrounds muscles and organs.
Biomechanics
Biomechanics involves the study of movement and forces acting on the musculoskeletal system. After surgery, normal biomechanics can be disrupted due to scar tissue formation. Adhesions can restrict movement by limiting the gliding of muscles and tendons over one another or by immobilizing joints. This altered biomechanics can lead to compensatory patterns that further exacerbate pain and dysfunction.
Comman symptoms
The symptoms of M96.842 can vary based on the severity of the condition:
Mild Severity
- Mild discomfort or aching in the affected area
- Slight stiffness during specific movements
- No significant impact on daily activities
Moderate Severity
- Persistent pain that may radiate from the surgical site
- Noticeable stiffness limiting range of motion
- Difficulty performing daily activities such as bending or lifting
- Possible muscle weakness due to disuse
Severe Severity
- Chronic pain that is debilitating and affects quality of life
- Significant loss of range of motion in affected joints
- Marked weakness in surrounding muscles
- Possible development of compensatory movement patterns leading to further dysfunction
Red Flag
Clinicians should be vigilant for red flags indicating potential complications:
- Severe Pain: Unresponsive to analgesics or worsening over time.
- Signs of Infection: Fever, redness, swelling, or drainage at the surgical site.
- Neurological Symptoms: Numbness or tingling suggesting nerve involvement.
- Persistent Dysfunction: Failure to progress in rehabilitation despite adherence.
Referral to an orthopedic specialist or physical therapist may be warranted if these symptoms arise.

Adhesions can restrict movement by limiting the gliding of muscles and tendons over one another or by immobilizing joints. This altered biomechanics can lead to compensatory patterns that further exacerbate pain and dysfunction.
Causes & Risk Factors
Pathophysiology
Scar tissue forms as part of the body’s natural healing process following injury or surgery. When tissues are damaged during surgical procedures, fibroblasts proliferate and produce collagen, leading to scar formation. While this process is essential for healing, excessive or disorganized collagen deposition can result in fibrous adhesions that tether structures together. This abnormal healing response can lead to:
- Restricted range of motion
- Pain due to nerve irritation
- Decreased functional capacity
Risk Factors
Several factors can increase the likelihood of developing post-surgical scar tissue:
- Type of Surgery: Procedures involving extensive soft tissue manipulation (e.g., joint surgeries) have a higher risk.
- Individual Healing Response: Genetic predispositions affecting collagen production may play a role.
- Age: Older adults may experience slower recovery and increased scar formation.
- Infection: Postoperative infections can complicate healing and increase adhesion formation.
- Previous Surgeries: History of multiple surgeries in the same area may predispose individuals to more extensive scarring.
Diagnostic Workup
Diagnostic Workup
Diagnosis of M96.842 typically begins with a thorough medical history and physical examination. Imaging studies may be utilized when necessary:
- X-rays: Useful for assessing bone integrity but limited in evaluating soft tissues.
- MRI: Provides detailed images of soft tissues and can help identify areas of scarring or adhesions.
- Ultrasound: Can be used to visualize soft tissue structures in real-time.
Physical Examination
A comprehensive physical examination should focus on:
- Assessing range of motion (ROM) in affected joints.
- Evaluating strength in surrounding musculature.
- Identifying areas of tenderness or trigger points.
- Observing functional movements relevant to daily activities.
Treatment & Rehabilitation
Effective management of M96.842 involves a structured rehabilitation program aimed at restoring function and reducing pain through a four-phase protocol:
Phase 1: Acute Management (0-2 Weeks)
Goals:
- Reduce pain and inflammation
- Protect the surgical site
Interventions:
- Modalities: Ice therapy, ultrasound therapy
- Gentle passive range-of-motion exercises within pain tolerance
- Education on activity modification
Exercises:
- Ankle pumps (for lower extremities)
- Gentle shoulder pendulum swings (for upper extremities)
Phase 2: Early Rehabilitation (2-6 Weeks)
Goals:
- Gradually restore range of motion
- Begin light strengthening exercises
Interventions:
- Continue modalities as needed
- Initiate active-assisted range-of-motion exercises
Exercises:
- Wall slides (for shoulder flexion)
- Heel slides (for knee mobility)
- Isometric contractions for surrounding muscles
Phase 3: Strengthening Phase (6-12 Weeks)
Goals:
- Improve strength and endurance

- Risk Management: Develop a comprehensive risk management plan that identifies high-risk activities and implements protocols to minimize exposure to conditions that may lead to musculoskeletal disorders.
Coding Examples
Patient presents with chronic low back pain following a previous spinal surgery. The physician documents that the patient has developed post-surgical instability resulting in musculoskeletal complications. Code as M96.842 because this code specifically addresses complications following surgery that affect the musculoskeletal system. Accurate coding is critical to ensure that the patient's ongoing management and treatment are appropriately documented and reimbursed.
Audit & Compliance
To support medical necessity and prevent claim denials for the ICD-10 code M96.842, the following documentation elements are crucial:
- Detailed Patient History: Comprehensive history of the patient's prior surgical interventions and any related musculoskeletal issues.
- Thorough Physical Examination: Document findings that clearly indicate the presence of post-surgical complications affecting the musculoskeletal system.
- Clear Diagnosis Statement: A definitive diagnosis that links the current symptoms to the prior surgical procedure, justifying the use of M96.842.
- Treatment Plan: An outlined plan detailing the interventions prescribed, including physical therapy, medications, or further diagnostic testing.
- Progress Notes: Regular updates that demonstrate the patient’s response to treatment and any changes in their condition.
Clinical Example
Subjective: A 52-year-old female presents with complaints of persistent lower back pain, rated 7/10. The patient states that the pain worsens with prolonged sitting and after physical activity. She has a history of spinal fusion surgery three years ago. Objective: Upon examination, there is tenderness over the lumbosacral region, with limited range of motion in the lumbar spine. Neurological examination reveals normal strength and sensation in both lower extremities. Assessment: Chronic low back pain, post-surgical instability secondary to previous spinal fusion. Diagnosis code: M96.842. Plan: Initiate a physical therapy program focusing on core strengthening and flexibility. Prescribe NSAIDs for pain management. Schedule a follow-up appointment in six weeks to reassess symptoms and adjust the treatment plan as necessary.
Differential Diagnoses
Several conditions may present similarly to M96.842; differential diagnoses should include:
- M25.561 - Pain in Right Shoulder: Joint pain unrelated to surgical history.
- M25.562 - Pain in Left Shoulder: Similar presentation without surgical context.
- M54.5 - Low Back Pain: May occur post-surgery due to compensatory mechanisms.
- M79.1 - Myalgia: Muscle pain not related to surgical intervention.
- M62.81 - Muscle Weakness: Generalized weakness not necessarily linked to scar tissue.
Differentiating these conditions from M96.842 is essential for appropriate management.
Documentation Best Practices
Accurate documentation is critical for proper billing under ICD code M96.842:
