Poisoning by, adverse effect of and underdosing of anesthetics and therapeutic gases (T41)

Browse all the diagnosis codes used for poisoning by, adverse effect of and underdosing of anesthetics and therapeutic gases (t41). For easy navigation, the diagnosis codes are sorted in alphabetical order and grouped by sections. Each section is clearly marked with its description, and the corresponding three-digit code range. This format makes it simple to browse diagnosis codes in this chapter or section and find what you're looking for. We've also added green checkmark icons to label billable codes, and red warning icons for non-billable ones. This makes it easy to identify which codes can be billed.

Clinical Information

Malignant Hyperthermia - Rapid and excessive rise of temperature accompanied by muscular rigidity following general anesthesia.

Instructional Notations

Type 1 Excludes

A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

  • benzodiazepines T42.4
  • cocaine T40.5
  • complications of anesthesia during pregnancy O29
  • complications of anesthesia during labor and delivery O74
  • complications of anesthesia during the puerperium O89
  • opioids T40.0 T40.2

7th Character Note

Certain ICD-10-CM categories have applicable 7th characters. The applicable 7th character is required for all codes within the category, or as the notes in the Tabular List instruct. The 7th character must always be the 7th character in the data field. If a code that requires a 7th character is not 6 characters, a placeholder X must be used to fill in the empty characters.

  • The appropriate 7th character is to be added to each code from category T41

7th Character

Indicates that a seventh character is to be assigned to codes in a subcategory.

  • D - subsequent encounter
  • S - sequela
