Excludes1 — never code together — inherited from T67

The conditions below can never be reported together with T67.8 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)
