Understanding Share of Cost for CalAIM and the Assisted Living Waiver (ALW) in California
Navigating Medi‑Cal programs can feel overwhelming, especially when it comes to understanding what you may need to pay out of pocket. Two programs that often raise questions are the Assisted Living Waiver (ALW) and CalAIM. A key concept within both programs is Share of Cost (SOC)—but how it applies can differ. This guide explains SOC in simple terms and clarifies how it works for ALW and CalAIM participants.
What Is Share of Cost (SOC)?
Share of Cost is the dollar amount a Medi‑Cal beneficiary must pay each month before Medi‑Cal begins covering services.
Think of it as a monthly deductible. Once you meet it for the month, Medi‑Cal pays the rest of your covered medical or long‑term care expenses.
Important points:
SOC is based on your countable income
It resets every month
Not everyone has a SOC—many low‑income Medi‑Cal beneficiaries owe nothing
How Share of Cost Works in the Assisted Living Waiver (ALW)
The ALW program helps eligible seniors and adults with disabilities receive care in approved assisted living settings instead of skilled nursing facilities. When it comes to SOC in ALW, here’s what to know:
How SOC Is Calculated in ALW
Your SOC is determined by:
Your monthly income
Minus the Medi‑Cal maintenance need amount (the amount you’re allowed to keep for personal needs)
Whatever remains becomes your Share of Cost.
Who Pays the SOC?
If you have a SOC, you pay it directly to the assisted living facility each month. This amount reduces what Medi‑Cal pays for your ALW services.
Example
Suppose you receive:
Monthly income: 1700
Allowed personal needs amount: 600
Your SOC would be approximately:
1700−600=1100
In this case, you would pay 1100 to the facility each month, and Medi‑Cal would cover the rest of the ALW rate.
Who Usually Has No SOC?
Most ALW residents receiving SSI (Supplemental Security Income) have zero SOC because their income is already below Medi‑Cal’s limit.
How Share of Cost Applies Under CalAIM
CalAIM (California Advancing and Innovating Medi‑Cal) is a statewide transformation of Medi‑Cal designed to coordinate care, address social needs, and improve health outcomes. Many people wonder if CalAIM creates its own SOC—but it doesn’t.
Key Points About SOC and CalAIM
CalAIM does not create a new Share of Cost
Your SOC is determined solely by your Medi‑Cal eligibility category
If you already have a SOC, it applies to CalAIM services such as:
Enhanced Care Management (ECM)
Community Supports (housing services, home modifications, transitions from nursing homes, etc.)
If you have no SOC under Medi‑Cal, CalAIM services are generally free
In short, CalAIM follows standard Medi‑Cal SOC rules.
Quick Summary

You pay SOC to the assisted living facility
It reduces the amount Medi‑Cal pays for your care
CalAIM
No separate SOC created
Any SOC you have is simply your normal Medi‑Cal SOC
Many participants qualify for CalAIM services at no added cost
Most Low‑Income Beneficiaries
