Rheumatoid myopathy with rheumatoid arthritis of left shoulder
ICD-10 M05.412 is a billable code used to indicate a diagnosis of rheumatoid myopathy with rheumatoid arthritis of left shoulder.
Rheumatoid myopathy is a condition characterized by muscle weakness and pain associated with rheumatoid arthritis (RA), an autoimmune disorder that primarily affects the joints. In this case, the left shoulder is specifically involved. The pathophysiology involves inflammation of the synovial membrane, leading to joint damage and muscle atrophy due to disuse and systemic inflammation. Clinically, patients may present with pain, swelling, and reduced range of motion in the left shoulder, along with systemic symptoms such as fatigue and malaise. Anatomically, the shoulder joint comprises the humerus, scapula, and clavicle, with surrounding muscles including the rotator cuff, deltoid, and pectoralis major. The inflammatory process can lead to muscle weakness and functional limitations, impacting daily activities and quality of life.
Orthopedic documentation should include imaging studies (e.g., X-rays, MRI) to assess joint integrity and functional assessments to evaluate range of motion and strength.
Common scenarios include surgical interventions for joint repair or replacement, and management of acute exacerbations of arthritis.
Joint-specific considerations include documenting the extent of joint damage and any surgical history related to the left shoulder.
Rheumatologic documentation must include laboratory tests for inflammatory markers (e.g., ESR, CRP) and assessments of disease activity (e.g., DAS28 score).
Typical scenarios involve managing systemic symptoms and adjusting DMARD therapy based on disease progression.
Consideration of systemic involvement is crucial, as RA can affect multiple organ systems beyond the musculoskeletal system.
Functional assessments should include evaluations of mobility, strength, and the need for assistive devices.
Rehabilitation scenarios may involve physical therapy to improve shoulder function and overall mobility.
Documentation should address mobility limitations and any adaptations required for daily living activities.
Used for rehabilitation of shoulder function post-RA exacerbation.
Document specific exercises performed and patient progress.
Physical therapy documentation should reflect the patient's functional limitations and goals.
Common symptoms include muscle weakness, pain, and fatigue, particularly in the proximal muscles, which can significantly impact daily activities and quality of life.
