Other reactive arthropathies, unspecified site
ICD-10 M02.80 is a billable code used to indicate a diagnosis of other reactive arthropathies, unspecified site.
Reactive arthropathies are a group of inflammatory joint conditions that occur as a reaction to an infection or other inflammatory process elsewhere in the body. The pathophysiology involves an immune-mediated response where the body mistakenly attacks its own joint tissues following an infection, often in the urogenital or gastrointestinal tract. Clinically, patients may present with joint pain, swelling, and stiffness, typically affecting the lower extremities, such as the knees and ankles, but can involve any joint. The condition may also be associated with systemic symptoms like fever and malaise. Anatomically, the joints affected are synovial joints, which are characterized by a joint capsule, synovial membrane, and articular cartilage. The inflammatory process can lead to synovitis, erosion of cartilage, and ultimately joint damage if not managed appropriately. Diagnosis is often supported by clinical evaluation, serological tests for inflammatory markers, and imaging studies to assess joint involvement.
Orthopedic documentation should include imaging results (X-rays, MRIs) showing joint involvement, functional assessments, and treatment plans detailing any surgical interventions.
Common scenarios include patients presenting with acute knee pain following a gastrointestinal infection or chronic joint pain with a history of urethritis.
Joint-specific considerations include the need to document the severity of joint swelling, range of motion limitations, and any surgical interventions performed.
Rheumatologic documentation must include laboratory results for inflammatory markers (e.g., ESR, CRP), patient history of infections, and disease activity assessments.
Autoimmune and inflammatory scenarios may involve patients with a history of reactive arthritis following a Chlamydia infection or gastrointestinal illness.
Systemic involvement may require documentation of extra-articular manifestations such as skin rashes or ocular symptoms.
Functional assessments should detail the patient's mobility limitations, pain levels, and rehabilitation needs, including any assistive devices used.
Rehabilitation scenarios may involve patients recovering from joint inflammation, focusing on restoring range of motion and strength.
Mobility limitations should be documented in terms of activities of daily living and any adaptations required for patient safety.
Used for joint effusion management in reactive arthropathies.
Document joint aspiration details, including the amount of fluid removed and any therapeutic agents injected.
Orthopedic considerations include the need for imaging guidance in some cases.
Common causes include infections such as Chlamydia, gastrointestinal infections, and other inflammatory conditions. The immune response to these infections can trigger joint inflammation.
