CAS Code 9 diagnosis invalid for patient's age

This cas code indicates the diagnosis code used is not appropriate for the age of the patient on the claim. Most of the time your clearinghouse will catch this BEFORE the claim goes out. But if you unfortunately do not use one that has these types of edits (you should move to Zirmed) you will need to address denials by re-coding the claim with the appropriate diagnosis code.

Just as some examples, you can't code any newborn diagnoses on someone who's 84 years old. Coding senile delirium on a 4 year old would also not be appropriate unless the patient is Benjamin Button.

To resolve this denial, review your coding, select a more appropriate diagnosis code and file a corrected or replacement claim.

Findacode is the best procedure lookup tool on the market and can easily help your coders see this before claims are released.
