S31.15 — Open bite of abdominal wall without penetration into peritoneal cavity
S31.15 is a non-billable header ICD-10-CM code for open bite of abdominal wall without penetration into peritoneal cavity. It cannot be billed on its own: choose one of the more specific child codes below. This code also requires a 7th character before it is complete.
This code requires a 7th character
The appropriate 7th character is to be added to each code from category S31
- A
- initial encounter
- D
- subsequent encounter
- S
- sequela

Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Bite of abdominal wall NOS
Other codes that can never be billed with S31.15
These codes carry an Excludes1 note pointing at S31.15. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading S31.15 alone.
- S30.87Other superficial bite of abdomen, lower back, pelvis and external genitals
Risk adjustment
S31.15 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
