S26.90Unspecified injury of heart, unspecified with or without hemopericardium

S26.90 is the ICD-10-CM diagnosis code for unspecified injury of heart, unspecified with or without hemopericardium. It belongs to category S26 (injury of heart), block S20-S29 (injuries to the thorax) 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 S26.9, choose S26.90 (Unspecified injury of heart, unspecified with or without hemopericardium) only when documentation doesn't support a more specific option: contusion of heart, unspecified with or without hemopericardium (S26.91), laceration of heart, unspecified with or without hemopericardium (S26.92) and other injury of heart, unspecified with or without hemopericardium (S26.99).

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.
