Nonadministration of surgical and medical care (Y66)
The ICD-10 code Y66 is used to classify cases where surgical or medical care was not administered as expected. This code specifically identifies situations of nonadministration, meaning that a needed medical or surgical treatment was not given.
Medical coders use Y66 to document incidents where appropriate healthcare procedures were skipped or omitted, which may impact patient outcomes or legal considerations. Unlike codes that describe errors during treatment, Y66 captures the absence of care itself. This includes both surgical and other medical interventions. Understanding this code helps healthcare professionals and coders accurately track cases of untreated medical needs and differentiate them from active treatment complications. If searching for the ICD-10 code for nonadministration of surgical and medical care, Y66 precisely denotes scenarios where the expected medical care was not provided.

A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!"
