Not billable
Is T61 billable?
No — T61 is a non-billable header code. T61 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 60 billable codes beneath T61.

Excludes1 — never code together
The conditions below can never be reported together with T61 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- allergic reaction to food, such as:
- anaphylactic reaction or shock due to adverse food reaction (T78.0-)
- bacterial foodborne intoxications (A05.-)
- dermatitis (L23.6, L25.4, L27.2)
- food protein-induced enterocolitis syndrome (K52.21)
- food protein-induced enteropathy (K52.22)
- gastroenteritis (noninfective) (K52.29)
- toxic effect of aflatoxin and other mycotoxins (T64)
- toxic effect of cyanides (T65.0-)
- toxic effect of harmful algae bloom (T65.82-)
- toxic effect of hydrogen cyanide (T57.3-)
- toxic effect of mercury (T56.1-)
- toxic effect of red tide (T65.82-)
Excludes1 — never code together — inherited from T51-T65
The conditions below can never be reported together with T61 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- contact with and (suspected) exposure to toxic substances (Z77.-)
Use additional code — inherited from Chapter 19
Report an additional code alongside T61 to fully describe the condition. T61 is sequenced first.
- code to identify any retained foreign body, if applicable (Z18.-)
Use additional code — inherited from T51-T65
Report an additional code alongside T61 to fully describe the condition. T61 is sequenced first.
Excludes2 — not included here — inherited from Chapter 19
The conditions below are not part of T61, but a patient may have both at the same time. When documentation supports it, T61 and the excluded code may both be reported.
