A health plan can look affordable until a regular prescription falls outside the pharmacy network, moves to a higher tier, or requires a new authorization. The year-end plan decision is easier when the medication list is complete before the plan is selected.
Quick Answer
Covered California’s 2026 open enrollment ran through January 31, but December 31 was the key deadline for coverage in place for January. All Covered California health plans include prescription drug coverage, yet each health plan has its own formulary and participating pharmacies. Before choosing a plan, check every regular prescription, the pharmacy network, the drug tier, expected cost, and any prior-authorization or quantity-limit rules. For specialty and compounded prescriptions, contact the health plan directly when the online drug search does not give a clear answer.
Why December 31 Matters for 2026 Coverage
Covered California’s December 22, 2025 reminder encouraged uninsured Californians to enroll by December 31 so coverage could be in place for January. Existing enrollees also had until the end of the year to make changes to their 2026 coverage.
Open enrollment itself did not end on December 31. It continued through January 31, 2026. The practical difference was the start date: selecting a plan by December 31 allowed coverage to begin January 1, while January enrollment generally started the following month.
- By December 31
- Coverage can be in place for January 1.
- January 1–31
- Open enrollment remained available for later coverage.
- Existing enrollees
- Year-end was also the point to make changes for the new plan year.
- Prescription reason to act early
- New-year formularies, networks and costs can differ from 2025.
Compare the Pharmacy Benefit, Not Just the Monthly Premium
Covered California states that all of its health plans have prescription drug coverage. That does not mean every plan covers each prescription in the same way. Every health plan maintains its own formulary, or covered-drug list, and patients also need to confirm which pharmacies can be used for plan benefits.
- Pharmacy network
- Confirm that the pharmacy you want to use participates in the plan.
- Formulary status
- Search each regular medication and identify its coverage tier.
- Plan restrictions
- Check prior authorization, step therapy and quantity limits when applicable.
- Expected prescription cost
- Review deductibles, copays, coinsurance and specialty-tier cost sharing.
Do Not Rely on Last Year’s Answer
Use the Type of Prescription to Ask Better Coverage Questions
The right benefit question depends on what kind of prescription you use. The selector below keeps the review simple without replacing the health plan’s own coverage decision.
Check a prescription coverage path
Standard formulary drug
Specialty medication
Compounded prescription
Compounded Prescriptions Need a Direct Plan Check
A compounded prescription may not appear in a standard formulary search the same way a commercially manufactured drug does. Coverage can depend on the health plan, the prescription, the ingredients, the dispensing pharmacy, and the claim rules that apply.
If a compounded prescription matters to your care, contact the health plan before enrollment and ask how that prescription would be processed. Useful questions include whether compounded prescriptions are covered under the pharmacy benefit, whether the pharmacy must meet network requirements, whether documentation is required, and how member cost sharing is determined.
The Health Plan Makes the Benefit Decision
Do not change the prescribed strength, dosage form, formulation, or treatment plan simply to fit a plan benefit. If a coverage problem requires a clinical alternative, discuss that decision with the prescriber.
Six Questions to Ask Before You Choose a 2026 Plan
01. Is the pharmacy I use in this plan’s pharmacy network?
02. Is each regular prescription on the 2026 formulary?
03. Which drug tier applies, and what will I pay?
04. Does any medication require prior authorization, step therapy, or a quantity limit?
05. How does the plan handle my specialty or compounded prescription?
06. Will my next refill fall before or after the new plan takes effect?

03. Search standard medications on the plan’s formulary.
04. Review prior authorization, step therapy and quantity-limit rules.
05. Compare expected prescription costs, not only the plan premium.
06. Ask the plan directly about specialty or compounded prescriptions that matter to your care.
