S93.01XD Subluxation of right ankle joint, subsequent encounter

ICD-10-CM S93.01XD: Subluxation of right ankle joint, subsequent encounter

ICD-10-CM code S93.01XD represents a subluxation of the right ankle joint during a subsequent encounter. The ankle joint complex includes the tibiotalar articulation. This specific code provides laterality and encounter specificity within the broader category of ankle joint subluxation and dislocation. A billable designation applies to this code for use in administrative healthcare contexts. 2 3 4

Plain-language overview

The true ankle joint is the tibiotalar joint, which is the articulation between the tibia, the fibula, and the talus. An abnormal separation at this talo-tibial joint constitutes an ankle dislocation. 2

What this code represents

Code S93.01XD specifically denotes a subluxation of the right ankle joint for a subsequent encounter. This code provides specific laterality and encounter status within the ICD-10-CM coding structure. 3 4

Coding details

The code S93.01XD is nested within the S93.0 category for subluxation and dislocation of the ankle joint. Related codes in this hierarchy include S93.01XA for the initial encounter and S93.01XS for sequela of the right ankle. 3

The designation for S93.01XD is identified as a billable code. The initial encounter for the same right ankle subluxation is designated by the code S93.01XA. 4

Documentation considerations

Clinical evaluation of ankle injuries involves palpation of the lateral ligaments, including the anterior talofibular ligament at the anterior aspect of the fibula. This examination assesses for tenderness or gaps indicative of rupture. 1

Plain radiographs for ankle injuries include anteroposterior, lateral, and mortise views. Weight-bearing views are preferred when tolerated to reveal subtle joint space widening or alignment abnormalities. 1

What the sources add

The clinical sources describe the anatomy of the ankle joint complex and the physical examination of ligaments, while the coding sources define the specific alphanumeric hierarchy and billable status of S93.01XD. 1 2 3 4

The clinical literature details the bony articulations of the ankle complex, and the coding references distinguish the subsequent encounter character of S93.01XD from initial and sequela encounters. 2 3
