How does share of cost work with IHSS?
IHSS is paid through Medi-Cal. If you have a share of cost, part of your IHSS provider’s pay may be your responsibility. The state can subtract the remaining share of cost from the provider’s payment. Read the share-of-cost notice and timesheet information together.
A simple example
$300 left for the month
Suppose your share of cost is $500. Qualifying medical costs of $200 have already been credited before the IHSS timesheet is processed. The remaining $300 may be deducted from the provider’s state payment. You would owe that amount to the provider.
Illustration only. Actual amounts depend on recorded expenses and processing.
Medi-Cal share of cost and IHSS: lower one, lower the other
The IHSS amount comes from your Medi-Cal share of cost, so anything that lowers the Medi-Cal number also lowers what you owe your caregiver. See how to lower a Medi-Cal share of cost, or estimate yours.
Talk before payday
Keep your provider informed. Save your medical receipts and share-of-cost notices. If the amount looks wrong, call the county IHSS office and ask how it was calculated.
A new policy does not approve IHSS
IHSS requires its own county review. Coverage, authorized hours, and caregiver enrollment are separate matters. A lower share of cost does not mean every hour of care will be paid.
Ask these three questions
- What share of cost is showing for this service month?
- Which medical costs have already been credited?
- If Medi-Cal changes my share of cost, what needs to happen to this timesheet?
Your next step
Keep your Medi-Cal decision and IHSS notices in one folder. Ask both offices which month a change affects.
Common questions
Do IHSS recipients have a share of cost?
Only if their Medi-Cal has a share of cost. IHSS itself does not create a separate one; it uses the Medi-Cal share of cost.
Who pays the IHSS provider when there is a share of cost?
The state pays the provider minus any unmet share of cost. The recipient pays that part to the provider directly.
Do I still need to apply for IHSS?
Yes. Buying insurance is not an IHSS application. IHSS has its own application, health certification, and county assessment.
