Rheumatoid polyneuropathy with rheumatoid arthritis of unspecified hand
ICD-10 M05.549 is a billable code used to indicate a diagnosis of rheumatoid polyneuropathy with rheumatoid arthritis of unspecified hand.
Rheumatoid polyneuropathy is a complication of rheumatoid arthritis (RA) characterized by peripheral nerve involvement due to systemic inflammation. The condition often presents with symptoms such as numbness, tingling, and weakness in the hands, which may be exacerbated by joint inflammation and deformities associated with RA. Anatomically, the peripheral nerves can be affected by inflammation, leading to neuropathic pain and functional limitations. The unspecified hand designation indicates that the specific hand affected is not documented, which can complicate treatment and rehabilitation strategies. Clinically, patients may exhibit joint swelling, stiffness, and reduced range of motion, particularly in the metacarpophalangeal and proximal interphalangeal joints. The pathophysiology involves immune-mediated damage to the nerves, often linked to the systemic effects of RA, including vasculitis and neuropathy. Early diagnosis and management are crucial to prevent further disability and improve quality of life.
Orthopedic documentation should include imaging studies (X-rays, MRIs) to assess joint damage and functional assessments to evaluate range of motion and strength.
Patients may present with joint deformities requiring surgical intervention, such as synovectomy or joint replacement.
Joint-specific considerations include documenting the severity of joint involvement and any surgical history.
Rheumatologic documentation must include laboratory tests for inflammation markers (e.g., ESR, CRP) and assessments of disease activity (e.g., DAS28 score).
Patients may experience flares of RA leading to increased polyneuropathy symptoms, necessitating adjustments in treatment.
Systemic involvement should be documented, including any extra-articular manifestations of RA.
Functional assessments should evaluate mobility, strength, and the need for assistive devices.
Rehabilitation scenarios may include therapy for improving hand function and managing pain.
Mobility limitations should be documented, particularly in relation to daily activities and occupational needs.
Used for initial assessment of functional limitations due to RA and polyneuropathy.
Detailed evaluation of range of motion, strength, and functional capabilities.
Physical therapy documentation should reflect the impact of RA on mobility.
Common symptoms include numbness, tingling, weakness in the hands, and pain that may be exacerbated by joint inflammation. Patients may also experience difficulty with fine motor tasks.
