ICD-10-CM S92.042K: Displaced other fracture of tuberosity of left calcaneus, subsequent encounter for fracture with nonunion

ICD-10-CM code S92.042K identifies a displaced other fracture of the tuberosity of the left calcaneus during a subsequent encounter for fracture with nonunion. The terminology record classifies this concept as an injury or poisoning, situated under a broader parent code for the same left calcaneus fracture. 1

Plain-language overview

This diagnosis code applies to an injury concept involving a displaced fracture of the tuberosity of the left calcaneus, documented during a subsequent encounter for fracture with nonunion. 1

What this code represents

The official terminology record assigns the preferred name displaced other fracture of tuberosity of left calcaneus, subsequent encounter for fracture with nonunion to the code S92.042K, and maintains an active record status. 1

The semantic type assigned to this specific code is Injury or Poisoning, and the code has narrower concepts within the ICD-10-CM version 2026 terminology. 1

Coding details

The parent concept for S92.042K is S92.042, which represents a displaced other fracture of the tuberosity of the left calcaneus without the specific encounter or healing complication extensions. 1

The S92.042 subcategory covers displaced other fractures of the tuberosity of the left calcaneus across various encounter types and healing outcomes, including routine healing, delayed healing, nonunion, and malunion. 3

Documentation considerations

Clinical documentation for this diagnosis concept specifies a subsequent encounter for fracture with nonunion of the left calcaneus tuberosity, distinguishing it from initial encounters or routine healing. 1 3

Clinical context

Research evidence regarding displaced intra-articular calcaneal fractures indicates that surgical treatment may lead to improved outcomes for function, pain, and physical quality of life compared to conservative management. 2

What the sources add

While the official terminology record defines the exact code S92.042K, a separate coding guide provides operational context by confirming that the related code S92.042G is a billable ICD-10-CM code. 1 3

A clinical reference index lists S92.042K alongside other left calcaneus fracture codes with varying healing complications, such as S92.012K for a displaced fracture of the body with nonunion. 4
