ICD-10 S37
Non-Billable HeaderInjury of urinary and pelvic organs
About ICD-10-CM S37
ICD-10-CM code S37 represents Injury of urinary and pelvic organs. This is a non-billable header code in the Injury, Poisoning, and External Causes chapter (block S37). The 2026 edition of ICD-10-CM S37 became effective on October 1, 2025. Non-billable codes cannot be used as a primary or secondary diagnosis on a claim, use a more specific child code instead.
Coding Tips for S37
Specialist guidance from the PayerReady Medical Coding Team. Specificity warnings, HCC capture rules, sequencing notes.
Injury codes require a 7th character: A (initial encounter, active treatment), D (subsequent, healing/recovery), S (sequela, late effect of original injury). Codes with fewer than 6 characters need the placeholder X to bring them to 6 characters before adding the 7th. Wrong or missing 7th character is the #1 cause of injury claim denials.
Type 1 Excludes
Pure excludes, these codes can never be coded together with S37. The conditions are mutually exclusive (e.g., congenital vs acquired forms).
- obstetric trauma to pelvic organs (O71.-)
Type 2 Excludes
Not included here, the excluded code is not part of S37, but a patient may have both conditions at the same time. Both codes may be coded together when applicable.
- injury of peritoneum (S36.81)
- injury of retroperitoneum (S36.89-)
