M23.239 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. Short description: Derang of medial meniscus due to old tear/inj, unsp knee. The 2019 edition of ICD-10-CM M23.239 became effective on October 1, 2018.
This is the American ICD-10-CM version of S83.242A - other international versions of ICD-10 S83.242A may differ. Use secondary code (s) from Chapter 20, External causes of morbidity, to indicate cause of injury.

Medial meniscus extrusion (MME) is defined as medial displacement of the body of the meniscus beyond the outermost margin of the medial tibial plateau and is measured in the mid-coronal plane through the knee joint. The mid-coronal plane is defined as the slice with the largest area of the medial spine.
Meniscal extrusion is the result of any substantial disruption of the main circumferential collagen bundles. Tears resulting in extrusion include meniscal root tear, large radial tear (more than 50% of meniscal width) and large complex tears (more than one cleavage plane through the meniscus)1,2.
Meniscal extrusion or subluxation refers to the peripheral meniscal margin extending beyond the external aspect of the tibiofemoral compartment of the knee.
ICD-10-CM Code for Complex tear of medial meniscus, current injury, right knee, initial encounter S83. 231A.
A common cause of meniscal extrusion is root tear. Other causes include large radial tear (>50% of meniscal width) and large complex tears (>1 cleavage plane through the meniscus). 2, 3 Medial meniscus extrusion can independently cause knee pain (apart from the primary pathology).
A lesion of the medial meniscotibial ligament will result in meniscal extrusion, and repairing the joint capsule will eliminate the extrusion by returning the meniscus back to its original position.
The medial gutter is a fold of synovium in the posteromedial aspect of the joint where loose bodies may hide. Ballottement of this space is essential to ensure that no potential sources of pain exist within this region. The medial tibial plateau is larger in the sagittal plane than the lateral plateau (FIG 1).
What is a complex medial meniscus tear? Complex medial meniscus tears can mean many things. They can mean that they are large tears, which are reparable, or they can mean that they are very complex or macerated tears that are not reparable.
Medial meniscal root tears are “radial” tears within 1 cm of the meniscal root insertion or an avulsion of the insertion of the meniscus. These injuries have been reported to change joint loading due to failure of the meniscus to convert axial loads into hoop stresses.
242A for Other tear of medial meniscus, current injury, left knee, initial encounter is a medical classification as listed by WHO under the range - Injury, poisoning and certain other consequences of external causes .

Complex tear of medial meniscus, current injury 1 S83.23 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail. 2 The 2021 edition of ICD-10-CM S83.23 became effective on October 1, 2020. 3 This is the American ICD-10-CM version of S83.23 - other international versions of ICD-10 S83.23 may differ.
Use secondary code (s) from Chapter 20, External causes of morbidity, to indicate cause of injury. Codes within the T section that include the external cause do not require an additional external cause code. Type 1 Excludes.
