There is only one immunization ICD10 code now. The code is Z23. The description of the code is “encounter for immunization.” You no longer have to specify what vaccine or whether it is oral or intramuscular in the diagnosis code.
For those of you using keywords to search, I am here to help. For my subscribed readers, sorry if this seems repetitive. When searching for the ICD10 replacement for a specific ICD9, your search engine will pick up the terms from this post and you will be able to find what you need in a way that wouldn’t be available with just the new code.
If you are billing a flu shot, use Z23
If you are billing a pneumo, use Z23
If you are billing Hep A or B, use Z23
If you are billing DTap, TDaP, Tetanus alone, or DT, use Z23
If you are billing polio, MMR, varicella, or Hib, use Z23
If you are billing HPV or meningococcal, use Z23
As always, if you have questions or have suggestions, call (909) 374-5439 or email firstname.lastname@example.org, or both.
