Excludes1 — never code together — inherited from T67

The conditions below can never be reported together with T67.4 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • erythema [dermatitis] ab igne (L59.0)
  • malignant hyperpyrexia due to anesthesia (T88.3)
  • radiation-related disorders of the skin and subcutaneous tissue (L55-L59)

Use additional code — inherited from Chapter 19

Report an additional code alongside T67.4 to fully describe the condition. T67.4 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 T67.4, but a patient may have both at the same time. When documentation supports it, T67.4 and the excluded code may both be reported.

  • birth trauma (P10-P15)
  • obstetric trauma (O70-O71)

Excludes2 — not included here — inherited from T67

The conditions below are not part of T67.4, but a patient may have both at the same time. When documentation supports it, T67.4 and the excluded code may both be reported.

  • burns (T20-T31)
  • sunburn (L55.-)
  • sweat disorder due to heat (L74-L75)

Code also — inherited from T66-T78

Two codes may be needed to describe the condition fully. Whether T67.4 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-)
