Ketamine injection coverage stance:
Clinical evidence and REMS-based administration constraints
Evidence summary and contexts where esketamine demonstrated benefit in trials
Effect sizes and time-course vary by study; some short-term trials did not meet primary endpoints.
Spravato and ketamine are not supported for certain uses outside their approved indications. Spravato is unproven and not medically necessary when used as an anesthetic agent, for chronic pain (including fibromyalgia, neuropathic pain, complex regional pain syndrome/Reflex Sympathetic Dystrophy), and for migraine headaches. Ketamine injection is considered investigational and not medically necessary for psychiatric disorders (including but not limited to depression, bipolar disorder, and PTSD), chronic pain conditions, and migraine headaches.
Spravato is not approved as an anesthetic agent; its safety and effectiveness as an anesthetic have not been established. In addition, compounded ketamine products (including oral formulations) have been the subject of a recent FDA warning identifying potential risks when used for treatment of psychiatric disorders. Providers and payers should note the lack of approval and the FDA advisory when evaluating requests for non‑labeled uses.
The FDA has issued a public warning about potential risks associated with compounded ketamine products, including oral formulations, for treatment of psychiatric disorders. This advisory underscores safety concerns and supports caution or exclusion of such compounded formulations for psychiatric indications in coverage determinations.
Spravato is considered unproven and not medically necessary when proposed as an anesthetic agent or for chronic pain and migraine. Ketamine injection retains an approved role for anesthesia (induction and supplementation) but is investigational and not medically necessary for psychiatric disorders, chronic pain conditions, and migraine. Coverage for esketamine is limited to its labeled psychiatric indications and subject to REMS program requirements.
Evidence for ketamine use in bipolar depression and as an adjunct to electroconvulsive therapy is limited and rated as low or insufficient quality by technology assessments. Reviews conclude that single‑dose intravenous ketamine may produce a rapid but transient antidepressant effect, while repeated infusions show greater and more durable effects; overall, Hayes assigned ratings such as C (potential but unproven benefit) or D2 (insufficient evidence) for these uses, indicating the evidence does not support routine coverage.

Provider Actions & Documentation
Prior Authorization & Documentation Required
Prior authorization is required for Spravato (esketamine) nasal spray. Submit documentation of diagnosis, prior antidepressant treatment failures (medication name, dates, duration), baseline depression assessment scores, and evidence that the prescribing provider and administration site are certified in the Spravato REMS program. Initial and reauthorization approvals are limited to no longer than 12 months.
- Prior authorization required for Spravato for TRD
- Document history of failure of at least two different antidepressants or regimens (each ≥ 8 weeks) including medication name, start/end dates, and duration
- Provide baseline scoring on an approved depression assessment (BDI, HAMD, MADRS, PHQ-9, QIDS) prior to starting Spravato
REMS Certification & Administration Requirements
Spravato must be dispensed and administered only in REMS-certified healthcare settings with patients enrolled in the Spravato REMS program. Administration must be performed under direct observation and the patient monitored for at least 2 hours after dosing. Coverage reviewers should verify REMS enrollment and that the provider/site certification is current.
- Patient must be enrolled in the Spravato REMS program prior to administration
- Administration only in REMS-certified healthcare setting
- Patient monitored ≥ 2 hours post-dose; documentation of monitoring must be submitted
REMS Documentation (What to Submit)
Document REMS-related evidence in the medical record: proof of patient enrollment in Spravato REMS, facility or provider REMS certification, and notes showing direct observation and post-dose monitoring. Failure to meet REMS requirements may result in denial of coverage.
- Attach REMS enrollment confirmation for the patient
- Attach provider/setting REMS certification documentation
- Include nursing/observation notes showing direct observation and monitoring duration
Prior Antidepressant Trial Documentation
Ensure prior antidepressant trial documentation shows failure of at least two different antidepressants or regimens (each ≥ 8 weeks). Include agent/class, dose, dates, reason for discontinuation (lack of efficacy, intolerance), and any augmentation strategies tried.
- List each antidepressant or regimen with start and end dates and duration (≥ 8 weeks each)
- State the reason for treatment failure for each trial (nonresponse, adverse effects, etc.)
- Include trials across classes when applicable (SSRI, SNRI, bupropion, TCA, MAOI, mirtazapine, augmentation with antipsychotic/lithium/thyroid)
Clinical Trial Context for Sequencing
Clinical trial evidence supports use of esketamine as adjunctive therapy to a newly initiated oral antidepressant and as monotherapy in TRD. When documenting sequencing, note whether Spravato is being used adjunctively with a newly started oral antidepressant or as monotherapy and include supporting clinical rationale.
- If used adjunctively, document initiation of the concurrent oral antidepressant and timing relative to Spravato dosing
- If used as monotherapy, document discontinuation of prior antidepressants if applicable and rationale for monotherapy use
- Reference supportive trial endpoints (e.g., MADRS score change at day 28) when relevant

Background
Major depressive disorder (MDD) is common and can be severe; a substantial minority of patients—approximately 30–40%—fail first‑line treatments and may meet criteria for treatment‑resistant depression (TRD). TRD is generally defined in this policy as failure to achieve clinically meaningful improvement after at least two different antidepressant trials given at adequate dose and duration, and esketamine (Spravato) is indicated for TRD and for depressive symptoms with acute suicidal ideation or behavior when used per FDA labeling and REMS requirements.
