Excludes1 — never code together — inherited from R40

The conditions below can never be reported together with R40.233 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • neonatal coma (P91.5)
  • somnolence, stupor and coma in diabetes (E08-E13)
  • somnolence, stupor and coma in hepatic failure (K72.-)
  • somnolence, stupor and coma in hypoglycemia (nondiabetic) (E15)

Code first — inherited from R40.2

The underlying condition below must be sequenced before R40.233. R40.233 describes a manifestation and cannot be the principal or first-listed diagnosis.

  • any associated:
  • fracture of skull (S02.-)
  • intracranial injury (S06.-)

  • certain conditions originating in the perinatal period (P04-P96)
  • signs and symptoms classified in the body system chapters
