S42.031S Displaced fracture of lateral end of right clavicle, sequela

ICD-10-CM S42.031S: Displaced fracture of lateral end of right clavicle, sequela

ICD-10-CM code S42.031S is an active terminology concept representing a sequela of a displaced fracture of the lateral end of the right clavicle. It is categorized as an injury or poisoning concept and exists as a narrower term under the parent code for the initial right lateral clavicle fracture. 1

Plain-language overview

Code S42.031S identifies a condition classed as an injury or poisoning, specifically denoting a sequela of a displaced fracture located at the lateral end of the right clavicle. 1

What this code represents

The terminology record establishes S42.031S as an active concept that is a narrower child of the parent code S42.031, which denotes a displaced fracture of the lateral end of the right clavicle. 1

Coding details

Within the S42.031 code tree, S42.031S is specifically designated for a sequela, distinguishing it from subsequent encounter codes for nonunion, delayed healing, or routine healing. 3

Clinical context

Clavicle fractures account for up to ten percent of all fractures, and a fall directly onto the lateral shoulder is the documented mechanism of injury in eighty-seven percent of reported cases. 2

Operative treatment for completely displaced and comminuted midshaft clavicle fractures demonstrates improved alignment, higher union rates, lower malunion risk, and faster return to function than nonoperative care. 2

Documentation considerations

The official terminology record for S42.031S specifies the right clavicle, the lateral end, the presence of displacement, and the sequela encounter type as the defined elements of this diagnosis concept. 1

What the sources add

While the terminology record provides the official code hierarchy and active status, the code tree listing illustrates how S42.031S operationally separates late effects from other specific healing outcomes. 1 3

The clinical reference adds background context on clavicle fracture mechanisms and management, whereas the official terminology record strictly defines the semantic type and parent hierarchy for S42.031S. 1 2
