Chronic instability of knee, right knee. M23.51 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2019 edition of ICD-10-CM M23.51 became effective on October 1, 2018.
Torn anterior cruciate ligament (ACL) definition and facts
Signs and symptoms of an ACL injury usually include:
ICD-10 code S83. 512A for Sprain of anterior cruciate ligament of left knee, initial encounter is a medical classification as listed by WHO under the range - Injury, poisoning and certain other consequences of external causes .
Athletes who attempt nonoperative management and continue to play sports with a chronic ACL tear frequently develop persistent knee instability which presents as a shifting sensation. They may also complain of swelling or locking which makes return to high-level sports that involve cutting and pivoting very difficult.
An ACL injury may develop into chronic ACL deficiency, which can lead to an unstable knee. Patients can develop an ACL deficiency if they have had an untreated ACL injury or an ACL injury that was unsuccessfully treated. ACL deficiency can cause damage to the joint and osteoarthritis.
ICD-10: Z96. 651, Status (post), organ replacement, by artificial or mechanical device or prosthesis of, joint, knee-see presence of knee joint implant.
The ACL Injury Grading System An ACL injury may be diagnosed when the ligament is overstretched or torn. The tear may be partial or complete; a complete tear of the ACL is also known as an ACL rupture. Grade I tears refer to a slightly stretched ACL. Symptoms are typically mild.
All ACL tears cannot be repaired. The ACL is attached to your thigh bone or femur and to your shin bone or tibia. Our current repair techniques only allow us to consider tears which occur high in the ACL near the femur insertion as a possible repair candidate. Also, the tear cannot be too old.
Grade 2: The ACL is stretched and becomes loose. This type of ACL injury is often referred to as a partial tear of the ligament. It is rare. Grade 3: Commonly referred to as a complete ligament tear (complete ACL tear), the ACL is split into two pieces and the knee is unstable.
Grade 3. Grade 3 ACL tears happen when the ACL is torn completely in half and is no longer providing any stability to the knee joint.
S83. 512A is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM S83. 512A became effective on October 1, 2021.
Other specified postprocedural statesICD-10 code Z98. 89 for Other specified postprocedural states is a medical classification as listed by WHO under the range - Factors influencing health status and contact with health services .
Superficial injury of knee and lower leg ICD-10-CM S80. 912A is grouped within Diagnostic Related Group(s) (MS-DRG v39.0):
Very minor tears (sprains) may heal with non-surgical treatments and regenerative medicine therapy. But full ACL tears cannot be healed without surgery. If your activities do not involve making pivoting movements on the knee, physical therapy rehabilitation may be all you need.
ACL injuries can either be complete or partial. While complete ACL tears almost always require surgery, partial ACL tears may be treated effectively with nonsurgical methods. ACL tears are graded by severity and are called sprains (a sprain is a stretch or tear in a ligament).
If left untreated, a small ACL tear will increase in size, causing more pain and increasing the laxity in the knee. Without a properly functioning ACL, the other structures of the knee experience greater strain, which causes further injuries to tissues in the knee.
What happens naturally with an ACL injury without surgical intervention varies from patient to patient and depends on the patient's activity level, degree of injury and instability symptoms. The prognosis for a partially torn ACL is often favorable, with the recovery and rehabilitation period usually at least 3 months.
The 2022 edition of ICD-10-CM S83.512A became effective on October 1, 2021.
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.
The term "ACL (or PCL) Deficient Knee" refers to a knee in which the ACL (PCL) is believed or known to be absent (i.e. a nonfunctioning ligament), particularly if the physical examination reveals/fulfills all the exam criteria for the "Diagnosis.". Usually the MRI will also confirm damage or tearing of the ACL (PCL) of varying degrees of severity.
So the "translation" of the diagnosis "ACL (PCL, etc.) Deficient Knee" is "Chronic/Old Tear of the ACL (PCL) Ligament.".
However, surgical treatment of a chronic meniscal tear ( degenerative, old traumatic, or otherwise) is not "experimental" if the patient's clinical problem is well/clearly explained by the meniscal tear, and the indications for surgical treatment of the tear are documented, i.e. Medical Necessity is fulfilled.
