Patient Timelines of Within-Year-Updated CMS-HCC Results

Object Description

One record per period in which the patient qualified for either the version 24 or version 28 CMS-HCC model; the blended RAF score is generated using the appropriate blending ratio for the calendar year of the period; the HCC/RAF results in any given period are calculated using only diagnoses present at the beginning of that period within the current calendar year.

Dedicated Precursors

• [SO/URSA-HCC] Patient Timelines of Within-Year-Updated CMS-HCC Results, Precursor 1 (Periods of Updated Results): One record per period with a start date on which the patient's HCC/RAF results might have changed, either because it's the start of a new calendar year or because a new qualifying diagnosis code was documented; these periods end on the start date of a new period, or the calendar year end date of the year containing the period start date, whichever comes first.
• [SO/URSA-HCC] Patient Timelines of Within-Year-Updated CMS-HCC Results, Precursor 2 (Patient-Periods and Diagnoses): One record per distinct qualifying patient-period or patient-diagnosis used to calculate HCC/RAF results for that period. We create distinct periods between which the patient's HCC/RAF results might change, and gather all diagnosis codes documented on that date or prior to that date in the same calendar year (representing the codes to be used to generate HCC/RAF results as of that date).
• [SO/URSA-HCC] Patient Timelines of Within-Year-Updated CMS-HCC Results, Precursor 3 (Version 24 Model Output): One record per patient-period during which the patient was eligible to generate HCC/RAF results; the HCC/RAF results in any given period are calculated using only diagnoses present at the beginning of that period within the current calendar year, using model version 24.
• [SO/URSA-HCC] Patient Timelines of Within-Year-Updated CMS-HCC Results, Precursor 4 (Version 28 Model Output): One record per patient-period during which the patient was eligible to generate HCC/RAF results; the HCC/RAF results in any given period are calculated using only diagnoses present at the beginning of that period within the current calendar year, using model version 28.
