Derangement of anterior horn of medial meniscus due to old tear or injury
ICD-10 M23.21 is a billable code used to indicate a diagnosis of derangement of anterior horn of medial meniscus due to old tear or injury.
M23.21 refers to a specific condition characterized by the derangement of the anterior horn of the medial meniscus, which is often a consequence of an old tear or injury. The medial meniscus is a C-shaped cartilage located in the knee joint, providing cushioning and stability. When an injury occurs, such as a tear, it can lead to mechanical instability, pain, and limited range of motion. Over time, the derangement may manifest as degenerative changes, including fraying or displacement of the meniscal tissue. Patients typically present with symptoms such as knee pain, swelling, and difficulty bearing weight. Diagnosis is often confirmed through imaging studies like MRI, which can reveal the extent of the tear and any associated joint changes. Treatment may involve conservative management, such as physical therapy and anti-inflammatory medications, or surgical intervention, including arthroscopic repair or meniscectomy, depending on the severity of the derangement and the patient's activity level.
Detailed operative reports, imaging studies, and pre-operative evaluations are essential.
Patients presenting with knee pain following sports injuries or degenerative changes.
Ensure that the documentation clearly states the type of meniscal injury and any associated ligamentous injuries.
Comprehensive assessments of functional limitations and treatment plans.
Patients undergoing rehabilitation post-meniscal surgery or those with chronic knee pain.
Document the patient's functional status and response to therapy to support the diagnosis.
Used when performing a meniscectomy due to derangement of the medial meniscus.
Operative report detailing the procedure and findings.
Orthopedic surgeons must document the specific meniscal pathology addressed during surgery.
M23.21 specifies derangement of the anterior horn of the medial meniscus due to an old tear or injury, while M23.20 is used for unspecified derangements of the medial meniscus.
