Federal old-age, survivors and disability insurance (1950- ); determining disability and blindness; extension of expiration date for cardiovascular system listing--Social Security Administration. Final rule.

We are extending the expiration date of the cardiovascular system listing found in appendix 1 of part 404, subpart P, from June 6, 1991, to June 6, 1992. We have made no revisions in the medical criteria in the cardiovascular listings; they remain the same as they now appear in the Code of Federal Regulations. We are presently considering revisions to update the medical criteria contained in part A and part B of the listing, and any revised criteria will be published as a proposed rule when we have completed our review. Insofar as Medicare eligibility is based on entitlement to disability insurance benefits under title II of the Act, this proposed regulation affects the Medicare program. To the extent that Medicaid eligibility is based on title XVI eligibility, this proposed regulation affects the Medicaid program.
