Bear with me here . . . and thanks for all the help!
What are the ICD-9 codes for Death by anaphylaxis: food allergy?
Are they E codes?
What other codes might be used -- primary, secondary, terciary in these situations of death -- both if accurately reported and if misreported?
(Example -- allergic reaction results in anaphylaxis results in blood pressure loss results in cardiac arrest results in death . . . so which of those ICD9 codes would be listed PRIMARY if done correctly? Which of those add'l codes might end up being used as PRIMARY if done incorrectly?)
Putting this quote here that I found & may shed some light on ONE direction I'm going with this:
We searched for diagnoses of ICD-9 code 995.0 (anaphylactic shock), E948.0 through E948.9 (adverse reaction from bacterial vaccines), and E949.0 through E949.9 (adverse reaction from other vaccines and biological substances). We restricted our review to diagnoses occurring on days 0 to 2 after vaccination (day 0 defined as the same day as vaccination) for ICD-9 code 995.0 and day 0 for ICD-9 codes E948.0 to E948.9 and E949.0 to E949.9. Because some cases of anaphylaxis may receive other related allergy diagnoses, at 1 of the study sites, we also performed a chart review of all day 0 diagnoses of 708.0 (allergic urticaria), 708.9 (urticaria unspecified), 995.1 (angioneurotic edema), 995.3 (allergy unspecified), 695.1 (erythema multiforme), and 995.2 (unspecified adverse effect of drug, medicinal and biological substance).
Quote is from study published 2003 as to # of cases of anaphylaxis death due to immunizations:

Connecting dots now.
Need some meaningful data regarding # of injuries due to LTFA -- non-ana AND anaphylactic would be ideal, but likely the best we'll get is something regarding anaphylaxis only. My estimation (and going from anecdotal info over the 12 years our family has been dealing with LTFA) is that most non-ana reax don't even end up seeking professional medical care, so there won't be ICD9 codes on record, etc.
Though it might be interesting to see a study of LTFA families and their use of med profession (and/or even reporting of reax) for non-ana reax. KWIM?
I am beginning to get where I'm going with this.
Anyone else?
But first, I really need help with the
ICD9 code questions to try to flesh out all the codes to use and flag.
