Non-billable headerICD-10-CM

X11.0 is a non-billable header ICD-10-CM code for contact with hot water in bath or tub. 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 X11

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

  • contact with running hot water in bath or tub (X11.1)

Risk adjustment

X11.0 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.

How X11.0 is indexed

Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to X11.0.
