Thread: Urgent Post-Op Ileus Question

    Default Urgent Post-Op Ileus Question

    AAPC: Back to School
    Hi All

    Quick (and I think easy) question: The case I am coding (obviously inpt as pt had a hemicolectomy) followed by a post-op ileus (definitive diagnosis); I'm all set with each of those!

    However I am at one of those "brain freezes"!!! :-)

    Do you code the "post-op vomiting after GI surgery" (ICD-9 564.3)? I know its just a symptom, and we have the definitive of an ileus, or do we leave it alone?

    Inpatient coding is not my areas of expertise. However, I would suggest the following:

    As per ICD guidelines "Additional signs and symptoms that are associated routinely with a disease process should not be assigned as additional codes, unless otherwise instructed by the classification.

    As per ICD 9 the dx "997.4" excludes "564.3". Hence, it is appropriate to report "564.3" as an additional dx.

    Hope this helps!
