    How many of you are using 401.0 for "uncontrolled hypertension"?

    Uncontrolled HTN is always coded as 401.9, see the guidelines for coding and reporting of dx.

    There is no controlled or uncontrolled unfortunately.

    Malignant hypertension, 401.0, is a life threatening condition. It is fatal if untreated.

    Benign, 401.1, is the most common type.

    Unless one of the above 2 is specifically stated by the provider you must default to 401.9, Unspecified.

    So you could have a patient with benign htn that is uncontrolled and the code would be 401.1.

    But that is the physician must document benign HTN. If the only doc is uncontrolled HTN then it is coded as 401.9.
