S40.87Other superficial bite of upper arm

S40.87 is the ICD-10-CM diagnosis code for other superficial bite of upper arm. It belongs to category S40 (superficial injury of shoulder and upper arm), block S40-S49 (injuries to the shoulder and upper arm) 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 S40.8, choose S40.87 (Other superficial bite of upper arm) only when documentation doesn't support a more specific option: abrasion of upper arm (S40.81), Blister (nonthermal) of upper arm (S40.82), external constriction of upper arm (S40.84), superficial foreign body of upper arm (S40.85) and insect bite (nonvenomous) of upper arm (S40.86).

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 S40.87 together with the conditions in its Excludes1 note: open bite of upper arm (S41.14).

The conditions in its Excludes2 note aren't part of S40.87, but may be coded alongside it if the patient has both: other superficial bite of shoulder (S40.27-).

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