T76.91 — Unspecified adult maltreatment, suspected
T76.91 is a non-billable header ICD-10-CM code for unspecified adult maltreatment, suspected. 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 T76
- A
- initial encounter
- D
- subsequent encounter
- S
- sequela
Excludes1 inherited from the categories above T76.91
These are not written on T76.91, but they bind it: a note on a category applies to every code beneath it. Billing T76.91 with anything listed here is a denial.
Written on T76 — Adult and child abuse, neglect and other maltreatment, suspected
- adult and child maltreatment, confirmed (T74.-)
- suspected abuse and maltreatment in pregnancy (O9A.3-, O9A.4-, O9A.5-)
- suspected adult physical abuse, ruled out (Z04.71)
- suspected adult sexual abuse, ruled out (Z04.41)
- suspected child physical abuse, ruled out (Z04.72)
- suspected child sexual abuse, ruled out (Z04.42)
Other codes that can never be billed with T76.91
These codes carry an Excludes1 note pointing at T76.91. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading T76.91 alone.
Risk adjustment
T76.91 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 T76.91 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 T76.91.

- Where does T76.91 sit in the tabular list?
- Injury, poisoning and certain other consequences of external causes (S00-T88), in the block Other and unspecified effects of external causes (T66-T78).
- What cannot be coded together with T76.91?
