Makes multiple textual revisions to subsection (m): removes or alters references to fiscal year 2029, limits certain provisions to fiscal years before 2029, modifies language regarding fiscal year 2028 to read "fiscal year 2028, or a subsequent even-numbered fiscal year," and deletes paragraph (11).

Adds new subparagraphs providing an appropriation of $15,000,000 for fiscal year 2030 for the pediatric quality measures program and a CPI-based increase rule for subsequent fiscal years; excludes subsections (e), (f), and (g) from applicability of these new subparagraphs.

Strikes subparagraph (I) from the express lane eligibility option provision.

Removes phrases that limited certain assurance-of-affordability standards and related permissions to periods ending September 30, 2029, replacing them with ongoing 'Beginning on' language.

Makes conforming amendments to the paragraph heading and revises timeframe language to state that the paragraph 'ends on September 30, 2029'.

Alters qualifying states option timeframe language by replacing 'for any of fiscal years 2009 through 2029' with 'for any fiscal year after fiscal year 2008'.

Modifies outreach and enrollment grant timing and set-aside language: removes several explicit end-year references (e.g., fiscal years 2009 through 2029) making some authorities ongoing beginning with FY2009; changes 10 percent set-aside references to apply 'for the period or the fiscal year for which such amounts are appropriated' and changes the 2024–2029 set-aside to 'Beginning with fiscal year 2024' wording; and adjusts subsection (g) text involving $40,000,000.

Revises dates and fiscal-year references in the child enrollment contingency fund provision: replaces limited-year ranges (e.g., '2024 through 2028') with 'beginning with fiscal year 2024' or 'fiscal year 2024 or any subsequent fiscal year' and adjusts references to 2023 and 2029.

Inserts a new subclause (IV) permitting, at the option of the State, coverage of children whose family income exceeds the maximum income level otherwise established for children under the State child health plan as of the date of enactment; also adjusts trailing 'or' wording in subclauses (II) and (III) to accommodate the addition.
