D0150: CMS OASIS Q&As

D0160 - Total Severity Score identifies the severity score calculated from responses to the PHQ-2 to 9. The Total Severity Score is a summary of the frequency scores on the PHQ2 to 9 that indicates the extent of potential depression symptoms. Item D0160 is used to report the total severity score for the Patient Mood Interview. The score in item D0160 is based upon the sum of the values that are contained in the following nine items: D0150A2, D0150B2, D0150C2, D0150D2, D0150E2, D0150F2, D0150G2, D0150H2, and D0150I2. The Scoring Rules explain how to compute the score that is placed in item D0160. These rules consider the "number of missing items in Column 2" which is the number of items in Column 2 that are blank (or skipped) or dashed.

• • • • •If all of the items in Column 2 have a value of 0, 1, 2, or 3 (i.e., they all contain nonmissing values), then item D0160 is equal to the simple sum of those values. If the number of missing items in Column 2 is equal to one, multiply the sum of the 8 items in Column 2 by 9/8 (1.125). If the number of missing items in Column 2 is equal to two, multiply the sum of the 7 items in Column 2 by 9/7 (1.286). If items D0150A through D0150I were asked and if Column 2 is equal to three or more, the interview is deemed NOT complete. Total Severity Score should be coded as “99”.
