Unspecified disorder of patella, unspecified knee
ICD-10 M22.90 is a billable code used to indicate a diagnosis of unspecified disorder of patella, unspecified knee.
M22.90 refers to an unspecified disorder of the patella, which is the kneecap, affecting the knee joint. This code is used when the specific nature of the disorder is not clearly defined. Common internal derangements associated with this code may include conditions such as patellar instability, chondromalacia patellae, or patellar tendinopathy. These disorders can lead to pain, swelling, and functional limitations in the knee. Meniscal tears, ligament injuries, and other knee pathologies may coexist but are not specified under this code. The diagnosis often arises from clinical evaluation, imaging studies, and patient history. Treatment may involve conservative management, such as physical therapy and medications, or surgical interventions like arthroscopy, which allows for direct visualization and treatment of the knee joint. Accurate coding is essential for appropriate reimbursement and to reflect the complexity of the patient's condition.
Detailed clinical notes, imaging results, and treatment plans must be documented to justify the use of M22.90.
Patients presenting with knee pain without a clear diagnosis, often following trauma or overuse.
Orthopedic surgeons should ensure that all potential diagnoses are explored before resorting to an unspecified code.
Functional assessments and treatment progress notes are essential for justifying the use of this code.
Patients undergoing rehabilitation for knee pain with unclear etiology.
Documentation should focus on the impact of the disorder on function and quality of life.
Used when the physician performs an arthroscopy to evaluate the knee joint for unspecified disorders.
Operative report detailing findings and any interventions performed.
Orthopedic surgeons should ensure that the diagnosis aligns with the findings during the procedure.
Use M22.90 when the specific disorder of the patella is not clearly defined in the clinical documentation, and all other specific codes have been ruled out.
