Highmark Blue Cross Blue Shield of Delaware administers pharmacy benefits through Express Scripts (ESI). For depression treatment, the ESI formulary typically places generic first-line antidepressants on lower tiers with minimal prior authorization requirements. Brand-name medications and specialty agents often require prior authorization (PA), step therapy documentation, or both.
Coverage and tier placement may vary by specific plan, employer contract, and formulary year. Members should verify their current formulary at highmarkbcbs.com or by calling ESI directly at 1-800-792-9558.

Delaware requires Electronic Prescribing of Controlled Substances (EPCS) for controlled substances under the Delaware Board of Medical Licensure and Discipline regulations (DE Admin Code, Title 24, § 1700). However, nearly all depression medications are non-scheduled and therefore fall entirely outside EPCS requirements.
| Medication Category | Examples | DEA Schedule | DE EPCS Requirement |
|---|---|---|---|
| SSRIs | Sertraline, escitalopram, fluoxetine, paroxetine | Non-scheduled | EPCS inapplicable |
| SNRIs | Venlafaxine ER, duloxetine, desvenlafaxine | Non-scheduled | EPCS inapplicable |
| NDRIs | Bupropion XL, bupropion SR | Non-scheduled | EPCS inapplicable |
| Atypicals & NaSSAs | Mirtazapine, trazodone, vortioxetine, vilazodone | Non-scheduled | EPCS inapplicable |
| TCAs | Amitriptyline, nortriptyline, imipramine | Non-scheduled | EPCS inapplicable |
| Auvelity (dextromethorphan/bupropion) | Auvelity | Non-scheduled | EPCS inapplicable |
| Spravato (esketamine nasal spray) | Spravato 56mg, 84mg | Schedule III | EPCS REQUIRED |
The key takeaway: for the vast majority of depression treatment, EPCS is not a barrier. Providers prescribing standard antidepressants via telehealth in Delaware are not subject to EPCS requirements for those medications. Only Spravato triggers EPCS. And its REMS in-office administration requirement means telehealth prescribing is not applicable regardless of EPCS status.
Spravato is the only depression medication in Delaware that triggers both EPCS and additional clinical program requirements. Patients and providers should be aware of all three layers:
Because Spravato is administered in-office and requires REMS certification, telehealth providers do not prescribe it directly. If Spravato may be appropriate for your treatment plan, your Klarity provider can coordinate a referral to a REMS-certified in-office facility.
Most generic first-line antidepressants on ESI’s formulary do not require PA. The primary scenarios where prior authorization or step therapy documentation may be required are:
Delaware’s mental health parity law. Del. Code Ann. tit. 18, § 3343. Aligns with the federal Mental Health Parity and Addiction Equity Act (MHPAEA). Under this law, fully-insured health plans regulated by Delaware are required to:
If you believe Highmark BCBS is applying more restrictive PA requirements or step therapy for your depression medication than it applies to comparable medical conditions, this may constitute a parity violation. You have the right to request the insurer’s NQTL analysis and to file a complaint with the Delaware DOI.
Note: § 3343 applies to fully-insured commercial plans regulated by Delaware. Self-funded employer plans (ERISA plans) are governed by federal MHPAEA rather than state parity law. For ERISA plan parity complaints, contact the Department of Labor’s Employee Benefits Security Administration (EBSA) at 1-866-444-3272.
If Highmark BCBS denies coverage for a depression medication or treatment, you have the right to appeal at multiple levels:
Klarity Health connects patients with licensed providers across Delaware who specialize in depression treatment, including medication management and therapy coordination. Our network of 2,000+ licensed providers can evaluate your symptoms, review your treatment history, and prescribe first-line antidepressants where clinically appropriate. Often within days of your first appointment.
Klarity providers are familiar with prior authorization documentation requirements for ESI and Highmark BCBS plans. When a PA is needed for a brand-name medication or a novel agent like Auvelity, your Klarity provider can support the documentation process.

Most generic antidepressants (SSRIs, SNRIs, bupropion, mirtazapine) are typically covered on ESI’s formulary at Tier 1. 2 with no prior authorization required. Brand-name and newer agents may require step therapy or PA. Verify your specific plan’s coverage by calling ESI at 1-800-792-9558.
Spravato may be covered under specialty pharmacy benefits through ESI, but it typically requires specialty PA, documentation of treatment-resistant depression (2+ failed adequate antidepressant trials), and enrollment in the REMS program. Spravato must be administered in a REMS-certified healthcare setting. It is not available for home use or via standard telehealth.
No. Virtually all standard antidepressants. SSRIs, SNRIs, bupropion, mirtazapine, TCAs, Trintellix, and Auvelity. Are non-scheduled and are not subject to Delaware’s EPCS requirement. Only Spravato (esketamine, Schedule III) triggers EPCS, and it is administered in-office rather than dispensed to patients.
ESI’s formulary for Trintellix (vortioxetine) typically requires documentation of at least one prior SSRI or SNRI trial at an adequate dose and duration. If a prior SSRI or SNRI was medically contraindicated or caused a significant adverse reaction, your provider may be able to request a step therapy exception with appropriate documentation.
Yes. You have the right to an internal appeal with Highmark BCBS, a peer-to-peer review between your provider and Highmark’s medical reviewer, and an independent external review through the Delaware Department of Insurance. If the denial implicates mental health parity rights, you may also file a complaint under § 3343.
Del. Code Ann. tit. 18, § 3343 applies to fully-insured commercial plans regulated by Delaware. If your coverage comes through a self-funded employer plan, federal MHPAEA applies instead. Contact Highmark at 1-800-241-5704 to confirm whether your plan is fully-insured or self-funded.
