A bill to amend title XVIII of the Social Security Act to provide that the periodic adjustments made in the inpatient hospital deductible shall hereafter reflect increases in social security cash benefits rather than increases in the cost of inpatient hospital services.

Directs the Secretary of Health, Education, and Welfare to determine and promulgate each year the hospital deductible applicable under the hospital insurance for the aged and disabled provisions of title XVIII (Medicare) of the Social Security Act.

Requires such deductible to be equal to $40 multiplied by the ratio of the current average per diem rate for inpatient hospital services for the preceding year to such rate for 1966.

Requires such deductible to be increased by a percentage equal to one-half of the average percentage of any general or cost-of-living increases in the social security cash benefits for the year.
