Reiter's disease, unspecified knee
ICD-10 M02.369 is a billable code used to indicate a diagnosis of reiter's disease, unspecified knee.
Reiter's disease, also known as reactive arthritis, is a type of inflammatory arthritis that develops in response to an infection in another part of the body. It is characterized by the classic triad of arthritis, urethritis, and conjunctivitis. In the case of M02.369, the unspecified knee indicates that the knee joint is involved, but the specific details of the condition are not documented. Anatomically, the knee joint consists of the femur, tibia, fibula, and patella, surrounded by ligaments, cartilage, and synovial fluid. Pathophysiologically, Reiter's disease is believed to be an autoimmune response triggered by infections, often involving the genitourinary or gastrointestinal systems. Clinically, patients may present with swelling, pain, and stiffness in the knee, which can lead to movement limitations and functional impairment. The condition may also affect other joints and can be associated with skin lesions and eye inflammation. Early diagnosis and management are crucial to prevent chronic joint damage.
Orthopedic documentation should include imaging studies (X-rays, MRIs) to assess joint damage, functional assessments, and treatment plans.
Common scenarios include joint injections, arthroscopy for diagnostic purposes, and surgical interventions for severe cases.
Documentation should specify the degree of joint involvement and any associated complications.
Rheumatologic documentation must include laboratory tests for inflammatory markers (ESR, CRP), and assessments of disease activity.
Scenarios often involve management of systemic symptoms and coordination with other specialties for comprehensive care.
Consideration of extra-articular manifestations and their impact on treatment decisions.
Functional assessments should evaluate mobility limitations, pain levels, and rehabilitation needs.
Rehabilitation scenarios may include physical therapy for joint mobility and strength training.
Documentation should address the need for assistive devices and modifications to daily activities.
Used for knee joint injection to relieve pain and inflammation.
Document the joint involved, the reason for the procedure, and any complications.
Orthopedic considerations include the need for imaging to guide the procedure.
Common symptoms include joint pain and swelling, particularly in the knees, along with possible conjunctivitis and urethritis. Patients may also experience systemic symptoms such as fatigue and fever.
