Clinical Information for Toxic effect of noxious substances eaten as seafood (T61)

Shellfish Poisoning - Poisoning from toxins present in bivalve mollusks that have been ingested. Four distinct types of shellfish poisoning are recognized based on the toxin involved.

Instructional Notations

Type 1 Excludes 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.

  • allergic reaction to food, such as:
  • anaphylactic reaction or shock due to adverse food reaction T78.0
  • bacterial foodborne intoxications A05
  • dermatitis L23.6 L25.4 L27.2
  • food protein-induced enterocolitis syndrome K52.21
  • food protein-induced enteropathy K52.22
  • gastroenteritis noninfective K52.29
  • toxic effect of aflatoxin and other mycotoxins T64
  • toxic effect of cyanides T65.0
  • toxic effect of harmful algae bloom T65.82
  • toxic effect of hydrogen cyanide T57.3
  • toxic effect of mercury T56.1
  • toxic effect of red tide T65.82

7th Character Note 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 T61

7th Character 7th Character
Indicates that a seventh character is to be assigned to codes in a subcategory.

  • A - initial encounter
  • D - subsequent encounter
  • S - sequela
