About S99.201

S99.201 is the ICD-10-CM diagnosis code for unspecified physeal fracture of phalanx of right toe. It belongs to category S99 (other and unspecified injuries of ankle and foot), block S90-S99 (injuries to the ankle and foot) and chapter 19 (injury, poisoning and certain other consequences of external causes). It is a header code, so it can't be reported by itself; one of its 7 subcodes must be used instead.

Within S99.20 (unspecified physeal fracture of phalanx of toe), S99.201 is specifically for unspecified physeal fracture of phalanx of right toe. Related codes cover left toe (S99.202) and unspecified toe (S99.209).

Codes in this range require a 7th character: A for initial encounter for closed fracture, B for initial encounter for open fracture, D for subsequent encounter for fracture with routine healing, G for subsequent encounter for fracture with delayed healing, K for subsequent encounter for fracture with nonunion, P for subsequent encounter for fracture with malunion and 1 more. Use placeholder "X" characters to fill any empty positions before the 7th character.

It was added in FY2017, effective October 1, 2016.
