Crestor Cost in Washington 2026: Rosuvastatin Prices, Insurance, and Savings

What Does Rosuvastatin Actually Cost in Washington Right Now?

Generic rosuvastatin runs about $15 per month at most Washington retail pharmacies in 2026, making it one of the least expensive branded-to-generic conversions in cardiovascular medicine. Brand-name Crestor carries a manufacturer list price of $290 per month from AstraZeneca, though almost no one pays that figure out of pocket.

The price gap matters. A patient filling 12 months of brand Crestor at list price would spend $3,480, compared to $180 for the generic. Since rosuvastatin lost patent exclusivity in 2016, multiple manufacturers now produce the drug, and that competition has driven retail cash prices well below $20 per month at most Washington chains.

Pharmacy-to-pharmacy variation still exists. Costco locations in Seattle and Spokane tend to price rosuvastatin calcium tablets at or below $10 for a 30-day supply. Independent pharmacies may charge slightly more, though many match big-box pricing when patients ask. The 40 mg strength sometimes costs $2 to $5 more per month than the 5 mg or 10 mg tablets, but this difference is minor.

Rosuvastatin is the most potent statin per milligram on the market. The JUPITER trial (N=17,802) demonstrated that rosuvastatin 20 mg reduced major cardiovascular events by 44% compared to placebo in patients with elevated high-sensitivity C-reactive protein and LDL cholesterol below 130 mg/dL [1]. That trial shaped current prescribing patterns and helps explain why rosuvastatin remains the second most-prescribed statin in the United States, behind atorvastatin.

For patients in Washington weighing cost against efficacy, generic rosuvastatin offers a strong ratio of clinical benefit per dollar spent. The 2018 AHA/ACC cholesterol guideline classifies rosuvastatin 20-40 mg as high-intensity statin therapy, the same tier as atorvastatin 40-80 mg [2].

Does Washington Medicaid Cover Crestor?

Washington Apple Health (Medicaid) covers rosuvastatin with prior authorization for hyperlipidemia and atherosclerotic cardiovascular disease prevention. The prior authorization requirement applies primarily to brand-name Crestor; generic rosuvastatin is typically available on the preferred drug list without added paperwork.

Washington's Health Care Authority manages the state Medicaid formulary. The preferred drug list generally favors generic statins (atorvastatin, simvastatin, rosuvastatin) over brand-name equivalents. If a prescriber requests brand Crestor specifically, they must submit a prior authorization form documenting clinical need, such as a documented intolerance or allergy to generic formulations.

Processing time for prior authorization varies. Most electronic submissions through the state's point-of-sale system receive a response within 24 hours during business days. Urgent requests can be expedited, though the Washington Health Care Authority recommends that prescribers submit requests before the patient arrives at the pharmacy to avoid delays.

Medicaid managed care organizations in Washington, including Molina Healthcare, Coordinated Care, and Community Health Plan of Washington, each maintain their own formulary preferences. Generic rosuvastatin appears on most of these formularies at the lowest copay tier. Copays for Medicaid enrollees in Washington are capped: adults pay no more than a few dollars per prescription under federal Medicaid rules, and children under 18 have no copays.

According to the CDC's National Health and Nutrition Examination Survey data, approximately 28% of adults over 40 use a statin, and that figure rises above 40% for adults over 60 [3]. In Washington, where Medicaid enrollment covers roughly 2 million residents, formulary access to generic rosuvastatin directly affects a large patient population.

Which Insurance Plans Cover Crestor in Washington?

Most commercial health plans in Washington cover generic rosuvastatin at a Tier 1 or Tier 2 copay, typically $5 to $25 per month. Brand-name Crestor sits at Tier 3 or higher on nearly all formularies, with copays ranging from $40 to $100 or more depending on the plan.

Here is how coverage breaks down by insurer type:

Employer-sponsored plans. Large employers in Washington (Amazon, Boeing, Microsoft, Starbucks) typically place generic rosuvastatin on their lowest copay tier. Step therapy is uncommon for rosuvastatin because it is already a first-line agent per AHA/ACC guidelines [2].

Individual marketplace plans (Washington Healthplanfinder). Plans sold through the state exchange are required to cover at least one statin per class under the essential health benefits mandate. Rosuvastatin, as a high-intensity statin, appears on most silver and gold plan formularies. Bronze plans may impose higher cost-sharing.

Medicare Part D. For Washington residents on Medicare, generic rosuvastatin typically falls in the preferred generic tier with copays of $0 to $10 per month. Under the Inflation Reduction Act provisions effective in 2025 and beyond, total out-of-pocket Part D spending is capped at $2,000 per year, which protects patients taking multiple branded medications [4].

Kaiser Permanente Washington. Kaiser's integrated formulary covers generic rosuvastatin with no prior authorization and a minimal copay. Brand Crestor requires a formulary exception.

Premera Blue Cross and Regence BlueShield. Both major Washington carriers list generic rosuvastatin as a preferred generic. Brand Crestor is classified as non-preferred brand, subject to higher copays and potential step-therapy requirements.

Patients who receive a rejection at the pharmacy should ask their prescriber to submit an appeal. The Washington Office of the Insurance Commissioner requires insurers to respond to standard appeals within 30 calendar days and urgent appeals within 72 hours.

Is Compounded Rosuvastatin Legal in Washington?

Yes. Compounded rosuvastatin is available through licensed 503A compounding pharmacies in Washington state. These pharmacies operate under the federal Drug Quality and Security Act and must also hold a valid Washington State Department of Health pharmacy license.

A 503A pharmacy compounds medications pursuant to individual patient prescriptions. This means a prescriber must write a specific prescription for a compounded rosuvastatin formulation, and the pharmacy prepares it for that individual patient. This differs from 503B outsourcing facilities, which can produce compounded medications in larger batches without patient-specific prescriptions.

Why would a patient need compounded rosuvastatin when generic tablets cost $15 per month? Several clinical scenarios justify compounding:

Dysphagia or swallowing difficulty. Some patients, particularly elderly stroke survivors or those with esophageal conditions, cannot swallow standard tablets. A compounding pharmacy can prepare rosuvastatin as a suspension or flavored liquid.

Pediatric dosing. The FDA-approved labeling for rosuvastatin includes a pediatric indication for heterozygous familial hypercholesterolemia in patients aged 8 and older [5]. Children who cannot swallow tablets may need a liquid formulation.

Allergy to excipients. Commercial rosuvastatin tablets contain inactive ingredients (lactose monohydrate, microcrystalline cellulose, and others) that cause reactions in some patients. Compounding removes the offending excipient.

Washington's compounding regulations align with federal 503A requirements. The state Board of Pharmacy oversees compliance. Patients should verify that their compounding pharmacy holds both a state license and appropriate federal registration. The Washington State Department of Health maintains a pharmacy license verification tool that patients can check before filling a compounded prescription.

Can You Get Crestor via Telehealth in Washington?

Telehealth prescribing of rosuvastatin is fully permitted in Washington. The state passed SB 5385 codifying telehealth parity, and the Washington Medical Commission allows prescribers to initiate statin therapy through audio-video or audio-only visits when clinically appropriate.

For rosuvastatin prescribing specifically, a telehealth visit typically involves reviewing the patient's lipid panel results, cardiovascular risk factors, and medication history. Most prescribers require a recent lipid panel (within 3-6 months) before starting or adjusting statin therapy. That lab work can be completed at any Washington lab (LabCorp, Quest, local hospital outpatient labs) and shared electronically with the telehealth provider.

Telehealth statin management follows the same clinical standards as in-person care. The 2018 AHA/ACC guideline recommends a clinician-patient risk discussion before initiating statin therapy, and this conversation can take place over video [2]. Follow-up lipid panels are typically drawn 4 to 12 weeks after starting therapy to assess LDL response, then annually.

Washington insurers are required to cover telehealth visits at the same rate as in-person visits under state law. This means the office visit copay for a telehealth statin consultation should match what the patient would pay for an in-person appointment.

HealthRX offers telehealth consultations for rosuvastatin prescribing, including lab review and prescription management, for Washington residents. Prescriptions can be sent to any licensed Washington pharmacy, including mail-order and compounding pharmacies.

Cheapest Ways to Fill Rosuvastatin in Washington

The lowest-cost option depends on insurance status. Here is a ranking from least to most expensive for a 30-day supply of rosuvastatin 20 mg in Washington:

1. Insurance generic copay: $0 to $15. If the plan covers rosuvastatin as a preferred generic, this is almost always the cheapest route.

2. Discount card or coupon programs: $8 to $18. GoodRx, RxSaver, and similar platforms negotiate cash-pay rates with Washington pharmacies. Costco, Walmart, and Fred Meyer tend to have the lowest discount-card prices. These programs are free to use and do not require insurance.

3. Retail cash pay: approximately $15. Washington's average cash price for generic rosuvastatin is around $15 per month. Some pharmacies charge less, some more.

4. Mail-order pharmacy: $10 to $30 for 90 days. Mail-order fills offer convenience and sometimes lower per-unit costs. Cost Plus Drugs, Mark Cuban's online pharmacy, lists generic rosuvastatin at a transparent markup over wholesale cost.

5. AstraZeneca savings programs. AstraZeneca no longer actively promotes a Crestor savings card for the brand product since generic entry, but the company does participate in patient assistance programs for qualifying uninsured or underinsured patients. Eligibility is typically limited to patients at or below 300% of the federal poverty level.

6. Washington State Prescription Drug Assistance Foundation (WPDAF). This nonprofit helps Washington residents access medications through manufacturer assistance programs. They can help manage paperwork for patients who qualify.

90-day fills save trips and sometimes money. Most Washington pharmacies and insurance plans allow 90-day supplies for maintenance medications like statins. Patients should ask their prescriber to write for a 90-day quantity with refills to maximize convenience.

Rosuvastatin Dosing, Efficacy, and Safety: A Clinical Overview

Rosuvastatin is dosed once daily, with or without food, at strengths of 5 mg, 10 mg, 20 mg, and 40 mg. The starting dose for most adults is 10 mg to 20 mg, depending on baseline LDL cholesterol and cardiovascular risk category.

High-intensity therapy (20-40 mg) typically reduces LDL cholesterol by 50% or more. In a head-to-head comparison, the STELLAR trial showed that rosuvastatin 40 mg lowered LDL by 55%, compared to 51% for atorvastatin 80 mg [6]. That difference is small, but rosuvastatin achieves similar LDL reductions at lower absolute doses, which may matter for tolerability. Muscle-related side effects with statins appear to be dose-dependent [7].

The JUPITER trial remains the defining study for rosuvastatin's role in primary prevention. Among 17,802 apparently healthy participants with LDL cholesterol <130 mg/dL and high-sensitivity CRP ≥2 mg/L, rosuvastatin 20 mg daily reduced the primary composite endpoint of myocardial infarction, stroke, arterial revascularization, hospitalization for unstable angina, or cardiovascular death by 44% (HR 0.56, 95% CI 0.46 to 0.69, P<0.00001) over a median follow-up of 1.9 years [1].

Dr. Paul Ridker, the JUPITER trial's principal investigator at Brigham and Women's Hospital, stated: "These data suggest that statin therapy may have a role in the primary prevention of cardiovascular events among persons who have elevated levels of C-reactive protein but who are not considered at high risk on the basis of lipid levels alone" [1].

Common side effects include myalgia (muscle pain) in approximately 5-10% of patients, headache, and gastrointestinal symptoms. Serious adverse events like rhabdomyolysis are rare, occurring at a rate of about 1.6 per 100,000 patient-years across all statins, according to FDA postmarketing surveillance data [8].

The USPSTF recommends statin therapy for adults aged 40 to 75 who have one or more cardiovascular risk factors (dyslipidemia, diabetes, hypertension, or smoking) and a 10-year ASCVD risk of 10% or greater (B recommendation), with selective use for those at 7.5% to 10% risk (C recommendation) [9].

Liver function monitoring has evolved. Current practice no longer mandates routine periodic liver enzyme testing for patients on statins. The FDA removed that requirement from statin labeling in 2012, recommending instead that liver enzymes be checked before starting therapy and as clinically indicated thereafter [8].

Brand vs. Generic: Is There Any Difference?

The FDA requires generic rosuvastatin to demonstrate bioequivalence to brand Crestor, meaning the generic must deliver the same amount of active drug to the bloodstream within a narrow window (80-125% for AUC and Cmax). All currently marketed generic rosuvastatin products met this standard in their Abbreviated New Drug Applications.

Patients occasionally report subjective differences when switching from brand to generic. A 2019 meta-analysis published in the Journal of the American Heart Association found no clinically meaningful differences in LDL lowering, cardiovascular outcomes, or adverse event rates between brand-name and generic statins across 24 studies involving over 100,000 patients [10].

The inactive ingredients do differ between manufacturers. Some patients with lactose sensitivity may notice gastrointestinal differences because rosuvastatin tablets from certain generic makers use slightly different filler compositions. If a patient experiences new symptoms after switching manufacturers, a trial of a different generic manufacturer's product is reasonable before concluding the patient "needs the brand."

In Washington, pharmacists may substitute a generic for the brand unless the prescriber writes "dispense as written" (DAW). State law permits generic substitution for all FDA-approved generic equivalents, and most insurance plans mandate it.

How Washington Compares to Other States

Washington's average cash price of $15 per month for generic rosuvastatin sits near the national median. Oregon, another Pacific Northwest state, averages roughly the same. California tends to be $1 to $3 higher at many retail chains. Idaho and Montana run slightly lower at some rural pharmacies but have fewer discount-pharmacy options.

Washington's Medicaid program covers rosuvastatin with prior authorization, which is standard. Some states (New York, Massachusetts) have more generous formularies where certain statin strengths are covered without PA. Others (Texas, Florida) impose similar or stricter step-therapy requirements.

The key advantage for Washington residents: the state's strong telehealth laws and high density of retail pharmacies (Costco, Fred Meyer, Walmart, independent pharmacies) mean that access to affordable rosuvastatin is excellent across both urban areas like Seattle, Tacoma, and Spokane and rural regions in eastern Washington.

For patients with LDL cholesterol above their risk-based target per the 2018 AHA/ACC guideline, starting rosuvastatin at 10-20 mg daily with a follow-up lipid panel at 4-12 weeks remains the standard clinical approach, and Washington residents can access that therapy for $15 per month or less at nearly any pharmacy in the state [2].
