Musculoskeletal condition M67.843 — ICD-10 M67.843

ICD-10: M67.843 | Category: Musculoskeletal Disorders | Billable: Yes

ICD-10 code M67.843 refers to "Other specified disorders of synovium and tendon, right shoulder." This condition typically involves a variety of musculoskeletal disorders that affect the synovial membrane and tendons in the shoulder region. Patients may experience pain, swelling, and impaired function due to inflammation or degeneration of these structures. Understanding this condition is crucial for clinicians, rehabilitation providers, and patients alike, as it can significantly impact daily activities and overall quality of life.

The shoulder is a complex joint composed of several anatomical structures, including:

• Glenohumeral Joint: The ball-and-socket joint formed by the humeral head and the glenoid cavity of the scapula.
• Rotator Cuff: A group of four muscles (supraspinatus, infraspinatus, teres minor, and subscapularis) that stabilize and move the shoulder.
• Bursa: Fluid-filled sacs that reduce friction between moving parts, particularly between tendons and bones.
• Tendons: Connective tissues that attach muscles to bones; in the shoulder, the rotator cuff tendons are particularly significant.

Biomechanically, the shoulder allows for a wide range of motion due to its structure but is also susceptible to injuries from repetitive use or acute trauma. The balance between mobility and stability is critical; any disruption can lead to conditions like tendinitis or bursitis.

Patient presents with persistent pain in the right wrist along with swelling in the surrounding tendons after a recent increase in typing hours due to work demands. Code as M67.843 because the documentation indicates other specified disorders of synovium and tendon, specifically related to repetitive strain injury.

To support medical necessity for coding M67.843 and prevent claim denials, the following key documentation elements are required:

1. Detailed Patient History: Include a comprehensive history of symptoms, duration, and any previous treatments or interventions.
2. Physical Examination Findings: Document specific findings related to the affected area, including tenderness, swelling, and range of motion limitations.
3. Diagnosis Justification: Clearly state the diagnosis and link it to the patient's symptoms and any relevant medical history or occupational factors.
4. Treatment Plan: Outline the proposed management strategies, including any referrals to specialists, prescribed therapies, and patient education provided.

Subjective: A 45-year-old female office worker reports a 3-month history of pain and swelling in her left wrist, particularly after extensive typing sessions. She describes the pain as a dull ache that worsens with activity and improves with rest. Objective: Upon examination, there is noticeable swelling over the left wrist area, with tenderness noted upon palpation of the extensor tendons. Range of motion is slightly limited due to discomfort, and grip strength is reduced compared to the right wrist. Assessment: The patient is diagnosed with a repetitive strain injury affecting the synovium and tendons in the left wrist, classified under ICD-10 code M67.843. Plan: The patient is advised to apply ice to the wrist to reduce swelling, utilize a wrist brace, and engage in physical therapy focusing on stretching and strengthening exercises. A follow-up appointment is scheduled in 4 weeks to monitor progress.

Differential diagnoses for M67.843 include:

1. Rotator Cuff Tear (ICD-10 Code M75.121): Characterized by acute pain and weakness; often confirmed via MRI.
2. Shoulder Bursitis (ICD-10 Code M75.51): Involves inflammation of the bursa; presents similarly but usually with more localized tenderness.
3. Adhesive Capsulitis (ICD-10 Code M75.0): Known as frozen shoulder; characterized by stiffness and limited range of motion without significant pain at rest.
4. Tendinitis (ICD-10 Code M75.11): Involves inflammation of specific tendons; often presents with pain during movement.

Accurate documentation is critical for billing under ICD-10 code M67.843:

1. Patient History: Document onset, duration, severity, and impact on daily activities.
2. Physical Examination Findings: Clearly note findings from inspection, palpation, range of motion tests, and strength assessments.
3. Imaging Results: Include details from any imaging studies performed.
4. Treatment Plan: Outline the rehabilitation protocol followed.

Ensure that all documentation supports medical necessity for billing purposes.
