At the end of Open Enrollment, the most useful comparison is prescription-by-prescription. A plan can look affordable at the premium level and still create a pharmacy problem if a regular medication is off formulary, the usual pharmacy is out of network, a specialty drug is placed on a higher tier, or the first premium is not paid before coverage is needed.
Quick Answer
Covered California Open Enrollment for 2026 ends January 31. People who enroll during January generally have coverage begin February 1. Before selecting a plan, review every prescription you expect to use and verify five things: whether the medication is on the plan’s formulary, which of the four drug tiers it occupies, which pharmacies can be used for the plan’s pharmacy benefit, whether a specialty prescription has additional plan requirements, and what the expected member cost may be. For a compounded prescription, contact the health plan directly rather than assuming the compound will process like a standard formulary drug. After choosing a plan, pay the first premium to activate coverage. After January 31, enrollment through Covered California generally requires a qualifying life event unless another enrollment pathway applies.
What the January 31 Deadline Means for 2026 Coverage
Covered California’s 2026 Open Enrollment runs through January 31. Covered California’s January 30 announcement described the deadline as midnight on January 31.
For people enrolling during January, coverage generally begins February 1. Once Open Enrollment ends, people usually need a qualifying life event to enroll through a special-enrollment period.

- After Open Enrollment
- A qualifying life event is generally needed to enroll through special enrollment.

The Deadline Is About Enrollment, Not Guaranteed Prescription Coverage
Enrolling in a Covered California plan gives access to that plan’s pharmacy benefit. It does not mean every prescription is automatically covered by every plan.
Start With the Prescriptions You Actually Use
Covered California says all of its health plans include prescription drug coverage, but each plan has its own formulary. That makes the medication list the best starting point for a final comparison.
Use the exact medication name, strength, dosage form, and expected refill pattern. A broad category such as “blood pressure medicine” or “specialty injection” is not specific enough to compare pharmacy benefits accurately.
What are you checking first?
Formulary
Check whether the exact prescription appears on the plan’s current drug list. Each Covered California health plan has its own formulary, so one plan’s answer does not establish another plan’s coverage.
Pharmacy network
Ask the health insurance company which pharmacies can be used for the plan’s pharmacy benefits. A familiar pharmacy should not be assumed to be in network.
Drug tier
Covered California groups prescriptions into generic, preferred, non-preferred and specialty tiers. The tier and metal level can affect the amount a member pays.
Specialty prescription
Confirm the specialty tier, expected member cost, required pharmacy channel, and any plan rule that could affect how the prescription is filled.
Compounded prescription
Give the health plan the exact compounded prescription and dispensing-pharmacy details. A standard formulary search may not answer how the finished compound will be processed.
Use the Exact Prescription Details
Strength, dosage form, and specific product can affect how a plan processes a prescription. Compare the current prescription rather than relying on a general medication category.
Five Pharmacy-Benefit Checks to Finish Before You Enroll
Covered California groups prescription drugs into four tiers: generic, preferred, non-preferred, and specialty. The metal level and the health plan can affect what a patient pays.
01. Is each regular prescription on the plan’s 2026 formulary?
02. Which drug tier applies to each prescription?
03. Is my current pharmacy in the plan’s pharmacy network?
04. Does any specialty prescription have a required pharmacy or other plan rule?
05. What is the expected cost before and after any pharmacy deductible?
06. If I use a compounded prescription, what does the plan say about this exact prescription and dispensing pharmacy?
- Generic
- Tier 1 in the standard four-tier structure
- Non-preferred
- Tier 3 can carry higher cost sharing than preferred medications.
- Preferred
- Tier 2 medications generally have a different cost-sharing level from generic drugs.
- Specialty
- Tier 4 prescriptions can have coinsurance or other higher-cost structures depending on the plan.
Specialty and Compounded Prescriptions Need a Direct Question
A specialty medication deserves more than a simple “covered” or “not covered” check. Ask which tier it occupies, whether a specific specialty pharmacy is required, what cost sharing applies, and whether the plan has any utilization or authorization requirement.
Compounded prescriptions are different because the finished preparation may not appear in the same way as a standard manufactured drug in an online formulary search. The safest approach is to contact the health plan with the exact prescription details and ask how the claim would be handled.
- Specialty tier
- Confirm the plan’s tier and expected member cost for the exact specialty prescription.
- Required pharmacy
- Ask whether the plan requires a particular pharmacy or specialty-pharmacy channel.
- Compounded prescription
- Ask how the exact compounded prescription would be processed rather than relying only on ingredient names.
- Final benefit decision
- The health plan is the source for final formulary, network, claim-processing, and member-cost rules.
Do Not Assume “Specialty Covered” Means the Current Pharmacy Will Work
A plan can cover a specialty medication while still requiring a specific pharmacy network or dispensing channel.
Do Not Forget the Step After You Choose the Plan
Covered California explains that after selecting a plan, the first bill is paid directly to the health insurance company. The plan needs to receive that payment before coverage is activated.
For prescription access, this matters because Covered California advises members to contact the insurance company to confirm the first payment was received and obtain a membership ID card or plan identification number. The insurer can also confirm which pharmacies can be used for pharmacy benefits.
- Select the plan
- Finish the enrollment choice before the January 31 deadline.
- Get plan identification
- Confirm the membership ID card or plan identification number with the insurer.
- Pay the first premium
- Make the first payment directly to the health insurance company to activate the plan.
- Confirm pharmacy access
- Ask the health plan which pharmacies can be used for its prescription benefit.
Plan Selection and Plan Activation Are Two Different Steps
A selected plan is not ready for pharmacy use until the insurer receives the required first payment and activates the coverage.

A Final Prescription-Benefit Checklist Before Enrollment Closes
Use one medication list for every plan you compare so the differences are easy to see.
01. List every prescription you expect to use during 2026, including specialty and compounded prescriptions.
02. Confirm that the pharmacy you expect to use participates in the plan’s pharmacy network.
03. Contact the health plan directly about any compounded prescription that does not have a clear formulary answer.
04. Check each standard prescription against the plan’s current formulary and drug tier.
05. Ask about any specialty-pharmacy requirement, authorization rule, deductible, coinsurance, or per-prescription cap.
06. After selecting the plan, pay the first premium and confirm activation before the next refill date.
