What if the admitting diagnosis code (Admit DX) is invalid or not subject to review?
If a message pops up that the admitting diagnosis code is an invalid code, please double check that the code is subject to review. Also check to make sure there is not a typo or any periods in this field. HSI posts Coding Job Aids on our Web site, which are lists of the ICD-9-CM admitting diagnosis codes subject to review. Please cancel out of the review.
