What Actually Happens on Spravato Observation Day — and What the Bill Will Say

Two questions come up constantly from people about to start Spravato (esketamine): what actually happens during the two-hour wait after the dose, and why does the insurance statement afterward look nothing like a normal doctor’s visit? Both have specific, sourced answers.

The problem: REMS observation feels opaque until you’ve done it once

Spravato is only available through the FDA’s Risk Evaluation and Mitigation Strategy (REMS) for esketamine, which means it can only be given in a certified healthcare setting, self-administered under a provider’s direct observation, with monitoring required for at least two hours after each dose before the patient can be discharged. as of 30 Apr 2025 · U.S. Food and Drug Administration That single requirement drives almost everything about how the visit feels and how it gets billed — but nobody explains the two pieces together in one place. This post does.

Steps: what the observation period actually involves

  1. Blood pressure check before dosing. Your clinic records a baseline blood pressure before you self-administer the nasal spray, because blood pressure commonly rises afterward. as of 30 Apr 2025 · U.S. Food and Drug Administration
  2. Self-administration under direct observation. You give yourself the dose; the provider does not administer it for you, but must watch you do it.
  3. A minimum two-hour clock starts. The clinic monitors blood pressure, alertness, and dissociative symptoms (things like altered perception or spaciness) for at least two hours. The clock does not start early and cannot be shortened — it is a floor set by the FDA label, not a clinic policy.
  4. A clinician decides you are ready to leave — based on your vitals and how you present, not on the clock alone. Some patients need longer than two hours.
  5. You arrange a ride home. You must not drive or operate machinery until the next day, after a full night’s sleep — not that evening, however clear-headed you feel. Plan a ride before you arrive, not after.

None of this is unique to any one clinic; it is the same nationwide REMS requirement wherever Spravato is dispensed, including every certified site in Florida.

Steps: what shows up on the bill

The observation requirement is not just clinical — it is priced into how the visit is billed, and the coding differs by payer type. As of early 2026:

  • Medicare bills the visit under one of two bundled procedure codes — G2082 (esketamine dose of 56 mg or less) or G2083 (more than 56 mg, typically the 84 mg maintenance dose) — which package the drug cost, the provider’s supervision, and the mandatory two-hour observation into a single line item. as of Feb 2026 · Osmind
  • Medicaid and commercial insurers generally bill the drug itself separately, using J0013, the permanent HCPCS drug code CMS introduced effective January 1, 2026 to replace the older temporary code S0013. Some commercial payers were still transitioning their systems and, during that window, continued to accept the older unclassified-drug code J3490 as a bridge. as of Feb 2026 · Osmind
  • The observation itself, when billed separately from the drug (as commercial payers typically do), is charged under an evaluation-and-management visit code plus additional prolonged-service units to cover the monitoring time beyond a standard appointment. as of Feb 2026 · Osmind

You do not need to memorize these codes. The useful habit is this: when your Explanation of Benefits (EOB) arrives, look for a drug charge and a separate monitoring or observation charge (if you have commercial insurance), or one combined charge (if you have Medicare) — and ask your clinic’s billing office to confirm which of these they submitted for your visit, since code sets update annually and a clinic’s system may lag a payer’s. If a charge looks unfamiliar, that question — “which code did you bill, and does it match what my plan expects for Spravato?” — will get you further with a billing office than any HCPCS number here.

The answer, in one line

The two-hour wait is a federal safety floor, not a clinic’s choice, and it is exactly what turns a Spravato bill into a bundled Medicare code or a separate drug-plus-observation charge on commercial insurance — knowing which one to expect makes an unfamiliar EOB much easier to read.
