Does Blue Cross Blue Shield of Arizona Cover Cialis?

How BCBSAZ Formulary Tiers Affect Cialis Coverage

Blue Cross Blue Shield of Arizona organizes covered medications into formulary tiers, and your tier placement determines what you pay at the pharmacy counter. Most BCBSAZ commercial plans use a four- or five-tier structure. Generic tadalafil typically falls on Tier 2 (preferred generic) or Tier 3 (non-preferred generic), while brand-name Cialis, when included at all, lands on Tier 4 (non-preferred brand) or the specialty tier.

Understanding the Tier Structure

Tier 1 carries the lowest copay, usually $5 to $15. Tier 2 generics run $15 to $40. Tier 3 non-preferred generics or preferred brands cost $40 to $75. Tier 4 and specialty tiers can exceed $100 per fill. Your plan's Summary of Benefits and Coverage (SBC) document lists the exact copay or coinsurance percentage for each tier.

Why Brand Cialis Costs More

Eli Lilly's patent on Cialis expired in 2018, opening the market to generic tadalafil manufacturers [1]. Because effective, FDA-approved generics exist, most insurers, including BCBSAZ, moved brand Cialis to non-preferred tiers or removed it from formularies entirely. A 2020 analysis published in JAMA Network Open found that generic entry for PDE5 inhibitors reduced average per-unit costs by 85% within two years of patent expiration [2]. That cost reduction is why insurers steer members toward generics.

Checking Your Specific Formulary

BCBSAZ maintains multiple formulary lists depending on whether you carry an employer-sponsored plan, an ACA marketplace plan, or a Federal Employee Program (FEP) plan. The fastest way to confirm your coverage is to log into the BCBSAZ member portal and search for "tadalafil" in the drug lookup tool. You can also call the member services number on your insurance card to request a benefits check.

Prior Authorization and Step-Therapy Requirements

Some BCBSAZ plans require prior authorization (PA) before covering tadalafil, particularly at higher doses or for the daily-use formulation. Step therapy may also apply, meaning your prescriber must document that you tried (and either failed or could not tolerate) a first-line option before the plan approves a second-line drug.

What Triggers Prior Authorization

PA requirements for tadalafil tend to activate in three situations: the prescriber writes for brand-name Cialis when a generic equivalent is available; the prescription calls for a dose above 20 mg; or the plan classifies all PDE5 inhibitors as PA-required. When PA is needed, your provider submits clinical documentation to BCBSAZ showing a diagnosis of erectile dysfunction (ED) or benign prostatic hyperplasia (BPH), along with confirmation that no medical contraindication to the drug exists.

Step Therapy in Practice

Step therapy for ED medications commonly requires a trial of generic sildenafil (Viagra's generic) before approving tadalafil. The American Urological Association (AUA) 2018 guidelines note that all PDE5 inhibitors show comparable efficacy for ED, with response rates between 60% and 70% across the class [3]. If sildenafil causes intolerable side effects (flushing, visual disturbances, headache) or fails to produce adequate results, your prescriber can submit a step-therapy exception with clinical notes documenting the inadequate response.

Timeline for Authorization Decisions

BCBSAZ typically processes standard PA requests within 72 hours for non-urgent cases. Urgent requests, where a delay could jeopardize the patient's health, receive a decision within 24 hours under Arizona Department of Insurance regulations.

Generic Tadalafil vs. Brand Cialis: Clinical Equivalence

Generic tadalafil contains the same active ingredient, at the same dose, in the same dosage form as brand Cialis. The FDA requires bioequivalence testing before approving any generic: the generic must deliver 80% to 125% of the brand's blood-level exposure, measured by AUC and Cmax parameters [4]. In practice, approved generics fall within a much narrower range, typically 96% to 104% of the brand.

Available Doses

Tadalafil comes in 2.5 mg, 5 mg, 10 mg, and 20 mg tablets. The 10 mg and 20 mg strengths are prescribed for as-needed use before sexual activity. The 2.5 mg and 5 mg daily-dose formulations treat both ED and BPH symptoms. The LUTS-BPH indication matters for insurance purposes because plans that exclude ED drugs from coverage may still cover tadalafil 5 mg daily when prescribed specifically for BPH [5].

Efficacy Data

In the original registration trial (N=348), tadalafil 20 mg improved erectile function domain scores on the IIEF by 7.9 points compared with 1.4 points for placebo (P<0.001) [6]. A pooled analysis of 11 placebo-controlled trials (N=2,102) confirmed that 81% of intercourse attempts were successful with tadalafil 20 mg versus 35% with placebo [7]. These data apply equally to all FDA-approved generic versions.

Duration of Action

Tadalafil's 17.5-hour half-life gives it the longest duration of action among PDE5 inhibitors, earning its clinical nickname of "the weekend pill." Sildenafil's half-life is 3 to 5 hours; vardenafil's is 4 to 5 hours [8]. This pharmacokinetic difference may be clinically meaningful for men who prefer spontaneity rather than timed dosing.

What BCBSAZ Medicare Advantage Plans Cover

Medicare Part D has historically excluded coverage for erectile dysfunction medications. This exclusion applies to most BCBSAZ Medicare Advantage Prescription Drug (MAPD) plans. The exclusion traces back to the Medicare Modernization Act of 2003 (Section 1860D-2), which gave Part D sponsors the option to exclude ED drugs, and nearly all chose to do so [9].

The BPH Workaround

If your physician prescribes tadalafil 5 mg daily specifically for benign prostatic hyperplasia (a covered Part D indication), some BCBSAZ MAPD plans will cover it. The prescription must carry the BPH diagnosis code (ICD-10: N40.1), not an ED code, and the plan must list tadalafil for BPH on its formulary. Coverage is not guaranteed, and PA is almost always required.

Supplemental Benefits

A small number of BCBSAZ MAPD plans offer supplemental OTC or prescription benefits that could offset ED drug costs. Check your plan's Evidence of Coverage (EOC) document, or call BCBSAZ Medicare member services at the number on your card, to confirm whether your plan includes any supplemental drug benefit.

Reducing Your Out-of-Pocket Cost for Tadalafil in Arizona

Even with insurance, copays for tadalafil can add up. Several strategies can lower your costs substantially.

Use the Generic

This is the single largest cost lever. Brand Cialis lists at roughly $450 for thirty 20 mg tablets. Generic tadalafil at the same quantity and strength costs $8 to $30 at major Arizona pharmacy chains (Costco, Walmart, CVS) using a discount card when insurance copays exceed the cash price.

Manufacturer and Pharmacy Discount Programs

GoodRx, RxSaver, and similar aggregators compile pharmacy-specific cash prices. At Arizona Costco locations, generic tadalafil (thirty 5 mg tablets) has been priced as low as $9.50 without insurance. Walmart's $4 generic list does not include tadalafil, but their discount program may still offer competitive pricing depending on the dose and quantity.

Ask About 90-Day Fills

BCBSAZ mail-order pharmacy benefits often provide a 90-day supply at the cost of two copays instead of three. If your plan allows mail order for tadalafil, switching from monthly retail fills to quarterly mail fills can cut your annual cost by a third.

Pill Splitting

For as-needed use, some prescribers write for tadalafil 20 mg tablets with instructions to split them into two 10 mg doses. Because the per-tablet price is similar across strengths, splitting effectively halves the per-dose cost. Confirm with your provider that splitting is appropriate for your prescribed dose before doing this. Tadalafil tablets are unscored, so a pill cutter is recommended for consistent halving.

When Tadalafil Is Prescribed for BPH, Not Just ED

Tadalafil 5 mg daily received FDA approval for treating signs and symptoms of BPH in 2011, based on four randomized controlled trials enrolling more than 1,500 men [5]. The LUTS/BPH indication changes the insurance equation because health plans that exclude ED medications may still cover tadalafil when the clinical documentation supports a BPH diagnosis.

Dual-Indication Patients

Many men have both ED and BPH. The AUA estimates that approximately 50% of men over age 50 experience some degree of BPH, and the prevalence of ED increases in parallel with age [10]. In a 2011 study (N=606), tadalafil 5 mg daily improved both IPSS (International Prostate Symptom Score) by 4.7 points and IIEF-EF scores by 6.1 points compared with placebo [11]. For BCBSAZ members who carry both diagnoses, having the prescription coded for BPH may improve coverage odds, though the prescriber must document the BPH indication accurately and truthfully.

Required Documentation

BCBSAZ may request supporting documentation including recent PSA levels, prostate exam findings, urinalysis results, and an IPSS questionnaire score. Having this documentation ready before the prescription is submitted speeds up the PA process.

Alternative PDE5 Inhibitors Covered by BCBSAZ

If tadalafil is not covered on your specific BCBSAZ plan, or if your copay is higher than expected, other PDE5 inhibitors may sit on a lower formulary tier.

Sildenafil (Generic Viagra)

Generic sildenafil is the most commonly covered PDE5 inhibitor and frequently appears on Tier 1 or Tier 2. It is dosed at 25 mg, 50 mg, or 100 mg, taken 30 to 60 minutes before sexual activity. The REVATIO brand of sildenafil (20 mg) is indicated for pulmonary arterial hypertension and is a different product, so the ED formulation must be specified.

Vardenafil (Generic Levitra)

Generic vardenafil became available in 2018 and appears on some BCBSAZ formularies at Tier 2 or Tier 3. Its onset of action (25 to 60 minutes) and duration (4 to 5 hours) are similar to sildenafil.

Avanafil (Stendra)

Avanafil remains brand-only and is typically Tier 4 or excluded on BCBSAZ plans. Its clinical advantage is a faster onset (15 minutes), but the premium price limits its insurance utility [12].

Comparing Options

The AUA does not rank one PDE5 inhibitor above another for first-line ED treatment. Efficacy rates across the class are comparable, with differences centering on pharmacokinetics, side-effect profiles, and food interactions [3]. Choosing the lowest-tier option on your specific BCBSAZ formulary will minimize cost without sacrificing clinical outcomes.

How to Appeal a BCBSAZ Denial for Tadalafil

If BCBSAZ denies coverage for tadalafil, you have the right to appeal. Arizona insurance law (A.R.S. § 20-2533) requires insurers to provide two levels of internal appeal before an external review can be requested.

Internal Appeal Process

Your denial letter will include instructions for filing an appeal. The first-level appeal goes to a BCBSAZ physician reviewer who was not involved in the original decision. Include a letter of medical necessity from your prescriber explaining why tadalafil is the appropriate drug (for example, documented failure of sildenafil, drug interaction precluding sildenafil use, or BPH as the primary indication).

External Review

If the internal appeal is denied, Arizona law allows you to request an independent external review through the Arizona Department of Insurance and Financial Institutions. The external reviewer's decision is binding on BCBSAZ.

Success Rates

Published data on PDE5 inhibitor appeal success rates are limited. A 2019 survey of managed-care pharmacy directors published in the Journal of Managed Care & Specialty Pharmacy found that step-therapy exception requests for ED drugs were approved approximately 62% of the time when the prescriber submitted documented clinical failure of the first-line agent [13].

Talking to Your BCBSAZ Prescriber About Tadalafil

A productive conversation with your prescriber improves the likelihood that insurance covers your medication.

What to Bring to the Appointment

Bring your BCBSAZ formulary list (downloadable from your member portal), your Summary of Benefits page showing prescription drug tiers, and any prior PA denial letters. Knowing your plan's requirements before the visit lets your prescriber write the prescription and PA paperwork simultaneously, avoiding a second round of phone calls.

Questions to Ask

Ask whether tadalafil daily (for BPH) versus as-needed (for ED) makes clinical sense for your situation, since the coverage implications differ. Ask whether pill splitting is safe for your prescribed dose. Ask whether a 90-day mail-order fill is an option. These are straightforward questions that can reduce your annual spending by hundreds of dollars.

Men with cardiovascular disease or those taking nitrates (nitroglycerin, isosorbide mononitrate) cannot safely use any PDE5 inhibitor. The ACC/AHA guidelines explicitly contraindicate concurrent PDE5 inhibitor and nitrate use due to risk of severe hypotension [14].
