Reiter's disease, knee
ICD-10 M02.36 is a billable code used to indicate a diagnosis of reiter's disease, knee.
Reiter's disease, also known as reactive arthritis, is an inflammatory condition that typically arises following a genitourinary or gastrointestinal infection. It is characterized by a triad of symptoms: arthritis, urethritis, and conjunctivitis. In the case of M02.36, the focus is on the knee joint, which is commonly affected. Anatomically, the knee is a complex hinge joint formed by the femur, tibia, and patella, surrounded by ligaments, cartilage, and synovial fluid. Pathophysiologically, Reiter's disease involves an autoimmune response where the immune system mistakenly attacks the joints, leading to inflammation, pain, and swelling. Clinically, patients may present with unilateral or bilateral knee swelling, stiffness, and reduced range of motion, often following an infection. The condition can lead to chronic joint damage if not managed appropriately, making early diagnosis and treatment crucial.
Orthopedic documentation should include imaging studies (e.g., X-rays, MRIs) to assess joint damage, as well as functional assessments to evaluate range of motion and stability.
Common scenarios include surgical interventions for severe joint damage or arthroscopic procedures to assess and treat intra-articular pathology.
Joint-specific considerations include the need to document the severity of inflammation and any structural changes observed in imaging.
Rheumatologic documentation must include laboratory tests for inflammatory markers (e.g., ESR, CRP) and disease activity assessments (e.g., DAS28 score).
Autoimmune scenarios may involve managing systemic symptoms alongside joint involvement, requiring a multidisciplinary approach.
Systemic involvement may necessitate monitoring for complications such as uveitis or skin lesions.
Functional assessments should evaluate mobility, pain levels, and the need for assistive devices to support rehabilitation efforts.
Rehabilitation scenarios may include physical therapy to restore function and strength following acute exacerbations.
Mobility limitations should be documented to justify the need for therapy and assistive devices.
Used for knee joint effusion management in Reiter's disease.
Document the indication for the procedure, joint involved, and any therapeutic agents used.
Orthopedic and rheumatologic considerations for joint aspiration and injection.
Common symptoms include joint pain and swelling, particularly in the knees, along with possible urethritis and conjunctivitis. Patients may also experience systemic symptoms such as fatigue and fever.
