Once again: 401.9 is a valid code

I have received another email from someone who attended my class asking me to verify that 401.9 is a valid code … others at her agency are telling her that it is not a valid hypertension code.

It is. 401.9 is valid. It is a useful code and one that you may have to use, depending on documentation.

401.9 is a valid code and is the correct code for HTN when no other information is available. It would be upcoding to change your hypertension code if you did not have additional information. There are many codes that we use that do not provide points, and this code is no longer case-mix. We must code according to the patient’s condition and the coding guidelines regardless whether the code is case-mix. Remember that if the patient has a heart condition, such as acute MI, chronic insufficiency, CAD or heart failure, then you’ve still earned those points that used to be awarded for 401.9.
