Idaho Medicaid Income Limits 2026: Chart by Household Size (Adult Medicaid, Pregnancy, CHIP)

Idaho's own chart, effective January 2026, lets one adult have up to $1,836 a month and a household of four up to $3,795 a month for adults, which is 138% of the federal poverty level. Every figure below comes from the state agency's own chart, effective January 2026 (page last updated 4-20-2026), not from federal averages or the old Medicaid.gov table.

  • Adult Medicaid (including Expansion): The page prints the table as monthly income by household size, effective January 2026, and adds $654 for each additional member; 138% is 133% plus 5 points (FedRateCalc arithmetic; the page does not say so).
  • Pregnancy Coverage: The table starts at a household of 2 and says the unborn child(ren) of a pregnant adult count as part of the household size; the amounts equal the adult table.
  • Children's Health Insurance Plan (CHIP): The page lists CHIP only from a household of 2 and no separate table for Medicaid for children. 190% is 185% plus 5 points, and 185% is the separate CHIP percentage in the Medicaid.gov table (as of December 1, 2023). Add $900 for each additional member.
  • The Department of Health and Welfare's "Medicaid Program Income Limits" page is marked "Page last updated: 4-20-2026" and each table is headed "Effective January 2026". It also lists the Medicare Savings Program, long-term care and other programs, which this page does not cover.
  • The Department's Pregnancy Coverage page says to be eligible for Medicaid for pregnant women you must live in Idaho, be pregnant, meet certain income guidelines and be a U.S. citizen or an eligible non-citizen. Its Medicaid Expansion page says people eligible for Medicare or another Medicaid program, disabled people and pregnant people are not in the expansion group.

How Idaho counts the 5 percent disregard

Federal rules tell states to subtract 5 percentage points of the poverty level from income for the eligibility group with the highest income standard. That is why some state charts print a percentage such as 133% and others print the total, such as 138%.

“Effective January 1, 2014, in determining the eligibility of an individual using MAGI-based income, a state must subtract an amount equivalent to 5 percentage points of the Federal poverty level for the applicable family size only to determine the eligibility of an individual for medical assistance under the eligibility group with the highest income standard using MAGI-based methodologies in the applicable Title of the Act, but not to determine eligibility for a particular eligibility group.”
42 CFR 435.603(d)(4) (source)

The household size in the chart for a pregnant woman counts the children she is expected to deliver:

“In the case of determining the family size of a pregnant woman, the pregnant woman is counted as herself plus the number of children she is expected to deliver. In the case of determining the family size of other individuals who have a pregnant woman in their household, the pregnant woman is counted, at State option, as either 1 or 2 person(s) or as herself plus the number of children she is expected to deliver.”
42 CFR 435.603(b), definition of family size (source)

In Idaho's chart, the amounts for Adult Medicaid (including Expansion); Pregnancy Coverage; Children's Health Insurance Plan (CHIP) equal a standard percentage plus 5 points (for example 138% is 133% plus 5) by FedRateCalc's arithmetic; the chart does not say the 5% disregard is included, so the checker adds nothing on top.

Idaho Medicaid programs and expansion

The Department of Health and Welfare says Idaho voters approved Medicaid Expansion in 2018, extending coverage to adults earning up to 138% of the federal poverty level, and that the program was implemented in January 2020. Medicaid.gov's table, as of December 1, 2023, shows 133% for Idaho.

  • Adult Medicaid (including Expansion). The Department of Health and Welfare lists Adult Medicaid (including Expansion) with one monthly income table; its Medicaid Expansion page says the program covers adults 19 through 64 who meet the income limits up to 138% of the federal poverty level and would not qualify for traditional Medicaid.
  • Pregnancy Coverage. The Department says Pregnancy Coverage provides pregnant women comprehensive health services throughout their pregnancy and up to 12 months postpartum care.
  • Children’s Health Insurance Plan (CHIP). The Department's CHIP page says CHIP is a low-cost health coverage program for children under age 19 whose family income is too high to qualify for Medicaid, with a small monthly premium that may depend on income. The Department's income limits page lists CHIP tables from a household of 2.
