Internal derangement of knee
Chapter 13:Diseases of the musculoskeletal system
ICD-10 M23 is a billable code used to indicate a diagnosis of internal derangement of knee.
Internal derangement of the knee refers to a variety of conditions that affect the knee joint's internal structures, including ligaments, menisci, and cartilage. Common causes include acute injuries, such as tears of the meniscus or ligaments, and chronic conditions resulting from repetitive stress or degeneration. Meniscal tears are particularly prevalent and can occur in various forms, including horizontal, vertical, and complex tears. Ligament injuries, such as anterior cruciate ligament (ACL) or posterior cruciate ligament (PCL) tears, can also lead to instability and pain. Symptoms typically include swelling, pain, limited range of motion, and a sensation of locking or giving way in the knee. Diagnosis often involves a combination of physical examination, imaging studies like MRI, and sometimes arthroscopy for direct visualization and treatment. Treatment options may include conservative management, such as physical therapy and bracing, or surgical interventions, including arthroscopic repair or reconstruction of damaged structures. Accurate coding is essential for proper reimbursement and to reflect the complexity of the patient's condition.
Detailed operative reports, imaging results, and pre-operative assessments are essential.
Meniscal repair, ACL reconstruction, and treatment of knee osteoarthritis.
Ensure that all surgical interventions are documented with specific details regarding the procedure performed.
Comprehensive evaluations, treatment plans, and progress notes are necessary.
Rehabilitation following knee surgery, management of chronic knee pain.
Document functional limitations and response to therapy to support coding.
Used when performing a diagnostic arthroscopy for internal derangement.
Document the findings and any procedures performed during the arthroscopy.
Orthopedic surgeons should ensure detailed operative notes are provided.
Used when a meniscal tear is surgically repaired.
Document the type of meniscal tear and the surgical technique used.
Orthopedic documentation must include pre-operative assessments and post-operative care plans.
M23.1 refers specifically to a medial meniscal tear, while M23.2 refers to a lateral meniscal tear. Accurate coding requires specifying the location of the tear.
M23.9 should be used when the specific type of internal derangement is not documented or when the details are insufficient to assign a more specific code.
