Lower or Eliminate Your Medi-Cal Share of Cost
- If Medi-Cal says you have a monthly Share of Cost, do not begin by purchasing insurance at random. First determine the exact monthly amount the county says must be reduced. Then check whether your existing health-insurance premiums and allowable medical expenses have already been counted.
- California Medi-Cal rules provide for the deduction of health-insurance premiums in applicable Medically Needy income calculations.
- See California Code of Regulations, Title 22, §50555.2
. - See the DHCS Non-MAGI Medi-Cal Guide
. - Your county eligibility worker makes the final determination for your individual case.
- See California Code of Regulations, Title 22, §50555.2
Which Best Describes Your Situation?
- I already know my monthly Share of Cost.
Compare the amount you need with the available dental, vision and Medicare-related premium options.
See options based on your Share of Cost. - I do not know the correct amount.
Use the Medi-Cal Share of Cost Calculator
as a preliminary estimate. Compare the result with your county Notice of Action or the amount supplied by your county worker. - I believe the county calculation may be wrong.
Check whether Medicare Part B, Part D, Medicare Supplement, dental, vision or other health-insurance premiums were omitted. You may also have medical expenses that may help lower your Share of Cost
.
Three Possible Ways to Avoid or Reduce Share of Cost
1. Correct the Existing Calculation
Before buying anything, verify the income, Medicare premiums, other health premiums and deductions used by the county. Sometimes Share of Cost can be reduced because an existing premium or expense was not counted.
2. Check the 250% Working Disabled Program
A person who meets the disability, work, income and other program requirements may qualify through the 250% Working Disabled Program
instead of remaining in Share of Cost Medi-Cal. Even part-time employment or self-employment may be relevant. Eligibility is determined by the county.
3. Add an Allowable Insurance Premium
If a monthly amount still remains, an appropriate dental, vision, Medicare Supplement or other health-insurance premium may help reduce it. The insurance should also provide benefits that you understand and can use. It is not merely a payment made to Medi-Cal.
- $1–$84 per month:
A basic dental or vision plan
may be sufficient. - $85–$425 per month: AmFirst Maximum Care
offers several premium choices within this range. - $426–$600 per month:
A combination of AmFirst Maximum Care
and another qualifying dental or vision premium
may be necessary. - $601 or more:
The situation should be reviewed individually before applying. Existing Medicare premiums,
Medi-Gap premiums
and other allowable expenses may need to be combined.
The current AmFirst application lists dental-plan premiums from $85 through $425 per month. Optional vision coverage may add another premium. Coverage is subject to application acceptance and approval.

Trying to Correct Past Months?
A carrier may sometimes approve an earlier effective date under its own requirements. However, purchasing coverage today does not automatically eliminate a past Share of Cost. Back premiums, prior claims, effective-date rules and county acceptance must all be reviewed.

- There are 2 ways to reduce or eliminate the Medi-Cal Share of Cost:
- 2. Buy health insurance each month to get rid of the monthly Medi-Cal Share of Cost.
- ► The money you spend on health insurance premiums each month will reduce your income so that you meet the Medi-Cal monthly income limits of $1,801 for a single person or $2,433 for a married couple.
- ► Example: If you are over the income limit by $50, you can buy a dental policy that costs $50 a month.
- ► Any health insurance premiums can be used to eliminate the Medi-Cal Share of Cost. For example:
- ► Dental or vision insurance;
- ► Medicare Part D drug plan;
- ► Medigap Insurance (private insurance policies that pay Medicare copayments and deductibles).
- ► Your Medi-Cal Social Worker can tell you how much you need to spend on health insurance to get rid of the Medi-Cal Share of Cost.
- Send proof of the extra health insurance to Medi-Cal
- ► Provide Medi-Cal office with written proof that you are buying health insurance on a monthly basis to eliminate the Medi-Cal Share of Cost. Medi-Cal office will update your Medi-Cal record to show that you have full Medi-Cal with no Share of Cost.
