CPI revision provides more accuracy in the medical care services component.
This revision, as in the past, enabled the Bureau to update medical care service expenditure weights in the CPI, including a more complete allocation of health insurance premiums. Instead of keeping the portion of premiums that go to benefits under health insurance, the expenditure weight for each benefit category has been added to the appropriate out-of-pocket expense. The unpublished health insurance item represents only the retained earnings portion of premiums paid by households. The specific item categories included in medical care services have also been updated and expanded. A study conducted during the developmental phase of the revision indicated that the Bureau should expand the eligible priced rates for physicians in the CPI to include not only the "self-pay" rate, but also other categories of payment as well. Another study indicated that the direct pricing of health insurance is not feasible because of the difficulty of factoring out from premium changes the effect of utilization levels and modified coverage. In pricing medical care service items, as with other item categories in the CPI, BLS attempts to exclude from price movement the effect of quality changes. However, some quality changes are difficult to assess or are not readily identified, for example, a change in the ratio of nurses to patients, and such changes may be reflected as part of the price change movement in the CPI.
