Coverage after large monthly medical bills (Medi-Cal Share of Cost)

Medi-Cal that can cover the rest of a high-bill month once qualifying expenses reach an amount the county sets.

What it is

Medi-Cal that can cover the rest of a high-bill month once qualifying expenses reach an amount the county sets.

This option may help when your income is above the usual child Medi-Cal limit and medical bills are high. The monthly share can be large. A disability-based calculation can differ from the family calculation, so the county needs to check both the amount and the bills.

Who can get it
  • Children under 21 can use this Medi-Cal category without a disability finding.
  • Ask the county who and what income each available calculation includes. Family, disability and waiver budgets can treat relatives and excluded income differently. Your social worker can help ask for the most favorable valid calculation.
  • The county checks assets only for a category that counts them. Ordinary MAGI child Medi-Cal has no asset test.
  • Ordinary child Medi-Cal has no savings test, but the Share of Cost route can count savings. Until June 2027 the limit is $130,000 for one person plus $65,000 for each other person; from July 2027 it drops to $21,000 for one, $31,000 for two, and $1,550 for each extra person. Ask the county which people and accounts belong in your child's budget.
With other insurance
  • The county reviews eligible medical expenses toward the monthly share.
What remains uncertain
  • The worksheet must show which expenses qualify after insurance and whether they reach the share in a particular month.
What you get
  • Medi-Cal for the rest of a month once eligible medical expenses reach the monthly share.
  • A separate disability-based calculation where the disability rules apply.
If you decide to apply
  1. Ask the county Medi-Cal worker or hospital counselor about a Share of Cost review through BenefitsCal. Ask them to compare the family and disability worksheets.
  2. Have ready: both parents’ pay stubs if that applies to your family, the oncologist’s diagnosis letter, bank balances and dated bills for the month you want covered. This route can have a savings limit.

What happens next
  • The decision standard is 45 days, or 90 when a disability finding is needed.
  • The notice names the monthly share and covered months. Qualifying bills must meet that share each month.
  • A share higher than any month’s qualifying bills may offer little practical help.
Good to know

The share resets each month. It does not automatically give access to CCS or paid IHSS hours.

What else to know
  • Ask for the county’s worksheet showing the maintenance allowance, income deductions and monthly Share of Cost. Total household wages alone cannot give you the answer.
  • Share-of-Cost coverage does not satisfy the no-share Medi-Cal financial route to CCS. The $40,000 or 20% route still needs review.
  • IHSS pays only after the monthly share is met. The county must confirm how continuous eligibility and monthly Share of Cost apply to your child’s aid category.
  • A bill can count toward the share before you pay it, as long as you still owe it.

Federal background: Medicaid through a medically needy or spend-down route. Medi-Cal with a Share of Cost.

Official sources
Ask your social worker

“Would a Share of Cost ever help with our child’s bills, or would the monthly amount be too high? Could you help us compare the family and disability calculations before we decide whether to apply?”

Why I’m asking: I want to know whether a month with large medical bills could qualify even above the usual income limit.

Who does what

The three parts, side by side. The agency decides; nobody on this page does.

You

Apply and say the words “medically needy, Share of Cost”. Ask for both worksheets in writing. Keep every bill from the month you want covered.

Your social worker

The social worker can send the oncologist's letter for the county disability finding and tell you which month's bills are large enough to matter.

The care team

The oncologist's diagnosis letter supports the county disability finding (acute leukemia meets the listing for 24 months).

Who decides
The county Medi-Cal eligibility worker (and the county disability evaluation unit for the disability-based budget)
Ask your social worker
“Can you help me ask the county for both the family and disability Share of Cost worksheets? Which month's bills would meet that amount?”

How to apply

First step: Apply at BenefitsCal.com or the county. Ask for Medi-Cal with a Share of Cost and both the family and disability worksheets.

  1. Ask the county for the Share of Cost worksheet under both the family budget and the disability-based budget.
  2. Ask which incurred bills count toward the share and how each month is certified.

Where it starts: BenefitsCal or the county. Ask for medically needy / Share of Cost review

What to gather

  • Pay stubs for both parents
  • The oncologist's diagnosis letter (for the county disability finding)
  • Every bill from the month you want covered, with dates
  • Bank balances (this option has a savings limit)

How long: 45 days. 90 days when the county disability finding is part of it.

What a yes looks like

A notice stating the monthly share and the covered months. Each month you show bills that meet the share and Medi-Cal pays the rest.

What a no looks like, and the next move

A notice with a share larger than any month's bills. Ask for the disability-based recalculation and check the CCS 20% option instead.

Watch out

  • Worked example only: two parents, two children and $8,000 a month in wages gives about $6,810 a month to meet. Other households need their own worksheet.
  • The same worked family's disability-based amount is about $2,858 a month. Acute leukemia meets the disability rule for 24 months; ask for both worksheets.
  • Share-of-Cost Medi-Cal does not count as full-scope Medi-Cal for CCS, so you still need the $40,000 or 20% CCS option. IHSS pays nothing until the share is met each month.
  • Share of Cost does not automatically use the waiver’s child-only asset budget. Ask the county whose assets count and which exemptions apply.

Dates that change this

not in force: The 138%-of-poverty maintenance-need reform (WIC 14005.12) is not operative. If implemented the level for four would be about $3,795.

2027-07-01: Non-MAGI asset limit $130,000 single / $65,000 per additional person from 2026-01-01. $21,000 / $31,000 from 2027-07-01.

The numbers and the rules

The arcane layer, kept on purpose. Checked September 10, 2026.

What it is worth

Medi-Cal for the rest of any month in which your medical bills reach the share. Roughly income before taxes minus $1,100 (family of four) each month, about half that under the disability-based budget.

  • $1,100/month — Maintenance need level, family of 4

Covers: Full Medi-Cal for the remainder of any month in which the share is met

What it costs the family: Worked example: two parents, two children and $8,000 a month in wages give about $6,810 monthly under family rules. Those rules deduct $90 per earner for work and $1,100 for basic needs. Disability rules give about $2,858 monthly in that example. They deduct $20 of any income and $65 plus half the remaining wages.

The eligibility facts, as published

Age
under 21 (age-linked. No disability finding needed to be in the category)
Income
any. The share rises with income
Asset test
non-MAGI asset limit ($130,000 single / $65,000 each additional person from 2026-01-01. $21,000 / $31,000 from 2027-07-01)
Budget unit
County determines the applicable family, disability or waiver budget and legally responsible relatives; people at the same address do not automatically form one unit.

Decisions this site cannot make: MFBU composition · Share of cost computation (family budget or ABD-MN budget) · County disability finding (DDSD) for the ABD budget

Expect friction on: Monthly certification of bills · Two worksheets to ask for

The trap: Treating the share as a premium. It is owed every month you use Medi-Cal, and Share-of-Cost Medi-Cal does not count as full-scope Medi-Cal for CCS. IHSS pays nothing until the share is met.
