T67 — Effects of heat and light
Is T67 billable?
No — T67 is a non-billable header code. T67 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 36 billable codes beneath T67.

Excludes1 — never code together
The conditions below can never be reported together with T67 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Excludes2 — not included here
The conditions below are not part of T67, but a patient may have both at the same time. When documentation supports it, T67 and the excluded code may both be reported.
Use additional code — inherited from Chapter 19
Report an additional code alongside T67 to fully describe the condition. T67 is sequenced first.
- code to identify any retained foreign body, if applicable (Z18.-)
Excludes2 — not included here — inherited from Chapter 19
The conditions below are not part of T67, but a patient may have both at the same time. When documentation supports it, T67 and the excluded code may both be reported.
Code also — inherited from T66-T78
Two codes may be needed to describe the condition fully. Whether T67 is sequenced first depends on the reason for the encounter.
- , if applicable, place of occurrence, such as:
- highway rest stop (Y92.523)
- school (private) (public) (state) as the place of occurrence of the external cause (Y92.21-)
- service areas as the place of occurrence of the external cause (Y92.52-)
- single-family non-institutional (private) house as the place of occurrence of the external cause (Y92.01-)
- transport vehicle as the place of occurrence of the external cause (Y92.81-)

How long has T67 existed?
T67 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
Which codes are confused with T67?
ICD-10-CM declares these codes mutually exclusive with T67 — exactly one of each pair can be correct for a given encounter.
