S36Injury of intra-abdominal organs

Non-billable headerICD-10-CM

S36 is a non-billable header ICD-10-CM code for injury of intra-abdominal organs. 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 S36

A
initial encounter
D
subsequent encounter
S
sequela

Code also

Both codes may be needed to describe the encounter fully. Sequencing depends on the reason for the visit.

  • any associated open wound (S31.-)

Other codes that can never be billed with S36

These codes carry an Excludes1 note pointing at S36. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading S36 alone.

Risk adjustment

S36 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.

Code to one of these instead S36

9 child codes. Green means billable.
