Excludes1: never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

  • mixed receptive-expressive language disorder (F80.2)
  • dysphasia and aphasia NOS (R47.-)

Excludes2: not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

  • acquired aphasia with epilepsy [Landau-Kleffner] (G40.80-)
  • selective mutism (F94.0)
  • intellectual disabilities (F70-F79)
  • pervasive developmental disorders (F84.-)
