S92.531B Displaced fracture of distal phalanx of right lesser toe(s), initial encounter for open fracture

ICD-10-CM S92.531B: Displaced fracture of distal phalanx of right lesser toe(s), initial encounter for open fracture

ICD-10-CM code S92.531B identifies a displaced fracture of the distal phalanx of the right lesser toe(s) during an initial encounter for an open fracture. This diagnostic label is classified under the semantic type of injury or poisoning. The available sources establish the code's official description and structural hierarchy but do not provide specific treatment guidelines for this exact toe injury. 3 6

Plain-language overview

Code S92.531B represents an injury or poisoning concept specifically identified as a displaced fracture of the distal phalanx of the right lesser toe(s) for an initial encounter for an open fracture. 3

What this code represents

The code S92.531B is listed alongside S92.531A, which identifies a displaced fracture of the distal phalanx of the right lesser toe(s) for an initial encounter for a closed fracture. 6

The broader coding category includes distinct variations such as S92.532B for a displaced fracture of the distal phalanx of the left lesser toe(s) during an initial encounter for an open fracture. 6

Coding details

The S92.53 code tree further differentiates injuries by displacement status, listing S92.534B as a nondisplaced fracture of the distal phalanx of the right lesser toe(s) for an initial encounter for an open fracture. 6

Documentation considerations

The official code label explicitly specifies right laterality, displaced fracture status, the distal phalanx of the lesser toe(s), and an initial encounter for an open fracture. 3

Clinical context

Clinical literature indicates that open fractures of foot bones require thorough debridement, wound lavage, fracture stabilization, and postoperative antibiotics. 2

What the sources add

The EVS Explore source provides the official code label and its semantic type, while the Unbound Medicine source provides the surrounding code tree showing laterality and encounter variations. 3 6

The clinical literature source discusses management for open metatarsal fractures, while the terminology source defines the distal phalanx toe fracture code, establishing a distinction between general foot injury management and the specific diagnosis. 2 3

Coverage and utilization context

Centers for Medicare and Medicaid Services articles list the S92.531B code description within billing and coding documents for tetanus immunization and preventive vaccine coverage. 4 5
