    Default Help with ICD-9 code for lab work

    AAPC: Back to School
    I have a patient who is obtaining lab work CBC, MAG, PHOS and diagnosis given is TPN dependence. What would you code for an ICD - 9 code to show TPN Dependence? This patient does have a cancer diagnosis and gastrostomy status. Any help would be great...

    What are you thinking about using for the TPN dependence?

    I think I would just use V44.1, gastostomy status, which is the reason for the TPN, the two go together and there doesn't seem to be a complication with the feeding, just monitoring.

    I wouldn't be using the cancer dx without that being indicated on the requistion or in the chart as the reason for the tests.

    We were maybe thinking V58.83 therapeutic drug monitoring. What are your thoughts?

    I like the V58.83 with a V58.69, and the V44.1 is a secondary only allowed dx code so you can use it but I do not see that being a reason for thr labs.

    I wasn't thinking of the TPN as a drug so much as food, but you're right. I think V58.83 is the best you're going to get because of the delivery system.
