About S70.37

S70.37 is the ICD-10-CM diagnosis code for other superficial bite of thigh. It belongs to category S70 (superficial injury of hip and thigh), block S70-S79 (injuries to the hip and thigh) 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 S70.3, choose S70.37 (Other superficial bite of thigh) only when documentation doesn't support a more specific option: abrasion of thigh (S70.31), Blister (nonthermal) of thigh (S70.32), external constriction of thigh (S70.34), superficial foreign body of thigh (S70.35) and insect bite (nonvenomous) of thigh (S70.36).

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.

Don't report S70.37 together with the conditions in its Excludes1 note: open bite of thigh (S71.15).

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