The term "mental retardation" offends some people and there was a suggestion to rename this diagnosis to "cognitive impairment". However, "mental retardation" it is the official term used by the WHO for this code, so it makes sense to stick to it. The explanation at the above link also clarifies that this is intended for developmental problems only, while "cognitive impairment" could be acquired or even temporary.

Additional Info

  • This is a manifestation, not a disease. It's mainly used when the underlying disease is not known, OR to especially code this entity when severe.
  • If you know the specific disease, it's even more important to code IT than to code this.
  • Includes developmental delay

Alternate ICD10s to consider coding instead or in addition


Candidate Combined ICD10 codes

  • Code the cause, if known.
