Recurring therapy and the 12-month limit
Weekly therapy is exactly the recurring case the rule contemplates — with a hard ceiling on how far ahead one estimate can reach.
Reviewed August 2026 · Not legal advice
Ongoing psychotherapy does not fit a document designed around a single procedure, and the regulation accounts for that. One estimate can cover a course of recurring care — with a firm ceiling on how far ahead it may reach.
The scope of a good faith estimate for recurring primary items or services must not exceed 12 months.
What a recurring estimate has to say
A single estimate covering recurring care must describe the expected scope in terms the client can actually evaluate: the number of sessions, how often, over what period. “Ongoing therapy” is not a scope. “Weekly 45-minute sessions, 48 sessions over 12 months” is.
That description is what makes the total meaningful. A client reading forty-eight sessions at $150 understands they are looking at $7,200 of care over a year and can decide accordingly. It is a more honest document than one showing a single session, and a considerably safer one if the bill is ever disputed.
The 12-month ceiling
Beyond twelve months, a new estimate is required. Therapy that continues into a second year needs a fresh document covering the next stretch — the original cannot simply be understood to roll forward.
This is the one deadline in the whole scheme that arrives without any prompt. There is no booking to trigger it and no client request; the anniversary simply passes. EstimateHarbor records the renewal date on every estimate and emails you before it lapses, which on the paid plans is most of the reason the reminder exists.
When the plan of care changes
The twelve-month limit is a ceiling, not a schedule. If your expectation changes materially inside the year — sessions move from weekly to fortnightly, your fee changes, a course you expected to run six months is clearly running longer — the estimate should be reissued to match. A revised estimate has to reach the client no later than one business day before the next scheduled session.
The reason is the dispute standard. Justifying charges above the estimate requires showing the excess arose from circumstances that could not reasonably have been anticipated. Care that visibly diverged from the estimate months ago is difficult to describe that way. Reissuing costs you a few minutes and keeps the document defensible. See the $400 rule.
Estimating a course of care you cannot predict
Therapists reasonably object that they do not know at intake how long someone will be in treatment. The rule asks for a good faith expectation, not a forecast. If your typical course for a presenting problem runs three to six months of weekly sessions, an estimate built on that is made in good faith even if this particular client finishes in eight sessions or continues for two years.
What is not defensible is estimating a single session because the future is uncertain. You expect more than one session; the estimate should say how many more you expect.
EstimateHarbor is not a law firm and this page is not legal advice. It summarises the federal rule at 45 CFR § 149.610 as we read it, for general information. Your state may impose additional requirements, and how the rule applies to your practice is a question for your own counsel or professional association.
