Editor's note: (1) House Bill 77-1646, which amended subsection (8)(d), was delivered to the governor on June 20, 1977. The general assembly adjourned sine die on June 22, 1977. The governor disapproved House Bill 77-1646 on July 15, 1977, but the bill was not filed with the secretary of state until July 27, 1977, and the governor's letter stating objections to the bill was not filed with the secretary of state until August 2, 1977. Because House Bill 77-1646 and the governor's objections to it were not filed with the secretary of state within thirty days after adjournment of the general assembly, House Bill 77-1646 became a law pursuant to the provisions of § 11 of article IV of the Colorado Constitution.
(2) Amendments to subsection (4) by House Bill 77-1419 and House Bill 77-1623 were harmonized.
(3) Amendments to subsection (8)(d) by House Bill 79-1393 and House Bill 79-1063 were harmonized.
(4) Amendments to subsection (11)(b) by Senate Bill 03-121 and House Bill 03-1350 were harmonized.
(5) Amendments to the introductory portion to subsection (2.5)(a) by Senate Bill 13-030 and Senate Bill 13-158 were harmonized.
(6) Section 34 of chapter 267 (SB 17-267), Session L aws of Colorado 2017, provides that the section of the act amending this section does not take effect if the centers for medicare and medicaid services determine that the amendments do not comply with federal law. For more information, see SB 17-267. ( L . 2017, p. 1447.) The executive director of the department of health care policy and financing did not notify the revisor of statutes by June 1, 2017, of such determination; therefore, amendments to this section took effect July 1, 2017.
(7) Subsection (11)(m)(II) provided for the repeal of subsection (11)(m), effective July 1, 2018. (See L . 2017, p. 1321.)
