    Default ICD9 guidelines

    To quote from 2009 ICD-9 Coding Guidelines, Chapter 7; a. Hypertension;
    7) Hypertension, secondary: Two codes are required: one to identify the underlying etiology and one from category 405 to identify the hypertension. Sequencing of codes is determined by the reason for admission/encounter.
