About coding kidney injury
The ICD-10-CM code for kidney injury is S37.00 (Unspecified injury of kidney). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on S37.00.
Within S37.0, choose S37.00 (Unspecified injury of kidney) only when documentation doesn't support a more specific option: minor contusion of kidney (S37.01), major contusion of kidney (S37.02), laceration of kidney, unspecified degree (S37.03), minor laceration of kidney (S37.04), moderate laceration of kidney (S37.05), major laceration of kidney (S37.06) and other injury of kidney (S37.09).
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.
