Subluxation and dislocation of patella The 2022 edition of ICD-10-CM S83. 0 became effective on October 1, 2021. This is the American ICD-10-CM version of S83. 0 - other international versions of ICD-10 S83.
The patella (kneecap) normally sits in a groove at the center of the bottom end of the thigh bone. A patellar subluxation means that the kneecap has briefly slid out of its normal place in that groove. In most cases the kneecap moves towards the outside of the body when it slides out of place.
Chronic instability of knee, left knee The 2022 edition of ICD-10-CM M23. 52 became effective on October 1, 2021. This is the American ICD-10-CM version of M23.
In a patellar dislocation, the patella gets pushed completely out of the groove. The other type of instability is known as chronic patellar instability. In this type, the kneecap usually only slides partly out of the groove. This is known as a subluxation.
Dislocation is injury to a joint that causes adjoining bones to no longer touch each other. Subluxation is a minor or incomplete dislocation in which the joint surfaces still touch but are not in normal relation to each other.
When you have a patella subluxation, the kneecap still tracks in the groove and you can still walk, but it may feel uncomfortable or unsteady, and you may hear a popping noise as it moves. A patellar subluxation can result from injury or from general looseness in the joint (patellar instability).
ICD-10 Code for Other instability, left knee- M25. 362- Codify by AAPC.
Other instability, unspecified joint M25. 30 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 M25. 30 became effective on October 1, 2021.
Patellofemoral instability is a result of malalignment of the patella in the trochlear grove caused by stretched or ruptured medial kneecap-stabilizers (traumatic) or anatomical anomalies of the knee joint.
Abstract. Medial patellar subluxation is a poorly recognized clinical condition characterized by chronic anterior knee pain that is exacerbated with knee flexion. Additional symptoms include instability, limited knee motion, and pain with squatting and stair climbing.
A subluxation is usually defined as a partial or incomplete dislocation.
Causes. Patellar dislocations can occur either in contact or non-contact situations. An athlete can dislocate his/her patella when the foot is planted and a rapid change of direction or twisting occurs. Usually a pre-existence ligamentous laxity is required to allow a dislocation to occur in this manner.
