About S96.899

S96.899 is the ICD-10-CM diagnosis code for other specified injury of other specified muscles and tendons at ankle and foot level, unspecified foot. It belongs to category S96 (injury of muscle and tendon at ankle and foot level), 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 3 subcodes must be used instead.

Within S96.89, choose S96.899 (unspecified foot) only when documentation doesn't support a more specific option: right foot (S96.891) and left foot (S96.892).

Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
