The solo prescriber's schedule: intakes, follow-ups, and therapy add-ons

The three visit types a prescriber's week is built from

A prescriber's week is assembled from three billable shapes: the psychiatric diagnostic evaluation that opens a case, the medication-management follow-up that carries it forward, and the psychotherapy add-on that attaches therapy time to a follow-up when the visit includes it. Each has its own code family, its own typical length, and its own place in the day, and the practice's economics come from how the three are combined rather than from any one of them.

The evaluation is the psychiatric diagnostic evaluation billed as 90791 1Ref 1APA Services, Inc. (2025).Psychotherapy Codes for Psychologists.That the psychiatric diagnostic evaluation (90791) opens a case and that psychotherapy add-on codes let therapy time be reported alongside a medication-management visit when the visit includes a distinct, separately timed block of psychotherapy.; when the first visit also includes the medical assessment that medication decisions require, a prescriber uses the evaluation code designated for services that include medical care. It is the longest, most cognitively demanding slot in the week, and it is where the diagnosis, the risk picture, and the initial plan are set.

The follow-up is the visit that carries the case between evaluations. In a prescriber's practice these are generally coded as evaluation-and-management visits, chosen on the complexity of the decision-making or the time spent — the med-management workhorse that fills most of the schedule.

The add-on is psychotherapy layered onto that med visit. When a follow-up includes a distinct block of psychotherapy, the psychotherapy add-on codes let that therapy time be reported alongside the medication-management service 1Ref 1APA Services, Inc. (2025).Psychotherapy Codes for Psychologists.That the psychiatric diagnostic evaluation (90791) opens a case and that psychotherapy add-on codes let therapy time be reported alongside a medication-management visit when the visit includes a distinct, separately timed block of psychotherapy.. The evaluation-and-management portion and the therapy portion are separate services with separate time — a distinction that matters both clinically and on the claim.

Why the intake-to-follow-up ratio is the number that matters

The ratio of new evaluations to established follow-ups is the quiet lever behind a solo psychiatric schedule. A week weighted toward intakes generates high per-visit revenue but never lets a panel settle, because every new case seeds a stream of future follow-up demand. A week that is almost all brief follow-ups fills the panel to capacity but leaves no room for the depth some patients need — and no slack when a stable case suddenly gets complicated.

A useful way to think about it is steady state: a panel stops growing when new intakes roughly balance the patients who taper out, transfer, or discharge. Below that, the panel keeps expanding and the follow-up backlog with it; above it, intake slots sit empty and revenue drops. Many solo prescribers protect a fixed number of evaluation slots per week precisely so the ratio does not drift on its own.

Whether the panel is built from insurance panels or private pay changes the arithmetic underneath, because the collected amount per visit — and therefore how many visits a sustainable week requires — moves with it. So does the session fee a private-pay practice sets and the payer allowances written into your fee schedule. None of these decides the mix by itself, but each one shifts how many follow-ups a solo has to run to keep the lights on, which in turn sets how much room is left for evaluations. The upstream funnel matters too: a practice that cannot move a patient from first call to first session in a reasonable window loses the intakes that feed every future follow-up.

Where psychotherapy add-ons fit — and where they don't

Psychotherapy add-ons let a prescriber bill therapy time delivered during a medication-management visit, using the add-on codes reported alongside the evaluation-and-management service 1Ref 1APA Services, Inc. (2025).Psychotherapy Codes for Psychologists.That the psychiatric diagnostic evaluation (90791) opens a case and that psychotherapy add-on codes let therapy time be reported alongside a medication-management visit when the visit includes a distinct, separately timed block of psychotherapy.. They fit the prescriber who does real psychotherapeutic work inside the visit and wants that work reflected on the claim rather than folded invisibly into a longer med check. They do not fit every visit, and reaching for them by default invites the scrutiny that any pattern of maximal coding attracts.

The add-on only holds up when two conditions are genuinely met. The evaluation-and-management service has to stand on its own — a real medication-management encounter with its own medical decision-making — and the psychotherapy has to be a distinct, separately timed block, documented with its own time and content. The time spent on the therapy cannot also be counted toward the E/M service; the two do not overlap.

For many solos the honest question is whether to provide the therapy at all or to refer it out. A prescriber who carries a full psychotherapy caseload alongside a medication panel is running two practices in one calendar, and the add-on math rarely rescues a schedule that is already overbooked. The add-on is a good fit for selective, clinically-indicated therapy inside a med practice — not a way to convert every follow-up into a longer, higher-paying visit.

Telepsychiatry as a scheduling lever, not just a convenience

Video visits are a scheduling instrument, not only a patient convenience. They compress the gaps a no-show would otherwise leave, extend a solo practice's reach beyond its immediate geography, and make a tight follow-up cadence easier to sustain because neither party loses travel time. The American Psychiatric Association's telepsychiatry materials treat the modality across its practice, legal, and reimbursement dimensions rather than as a single technology decision 2Ref 2American Psychiatric Association (2026).Telepsychiatry Toolkit.That video-based psychiatric care has practice, legal, and reimbursement dimensions a solo prescriber must plan around, including jurisdiction-specific licensure when a patient is located in another state..

For a solo, the practical wins are cadence and continuity: a patient who would skip an in-person follow-up in a busy month will often keep a fifteen-minute video visit, which keeps the case connected and the medication plan current. Telepsychiatry also lets a practice hold a mixed week — some in-person evaluations, some video follow-ups — matching the visit type to the format that serves it best.

The constraints are real and belong in the plan, not as afterthoughts. Licensure is jurisdiction-specific: a patient located in another state generally means practicing under that state's law, so the reach telepsychiatry offers is bounded by where the prescriber is licensed. Reimbursement for the audio-only and video variants, and the platform's privacy posture, are part of the same decision rather than separate ones.

Niche panels that reshape the whole schedule

A clinical niche does more than differentiate a practice — it changes the shape of the calendar. Two of the most common in solo psychiatry are office-based treatment of opioid use disorder and the drugs that carry a federal risk-management program, and each rewrites the visit mix in a way a generalist panel does not.

Office-based buprenorphine. The X-waiver was eliminated in 2023, so any prescriber with Schedule III prescriptive authority and a current DEA registration may prescribe buprenorphine for opioid use disorder, subject to the one-time DEA training attestation 3Ref 3Substance Abuse and Mental Health Services Administration (2026).Buprenorphine.That the X-waiver was eliminated in 2023 and any prescriber with Schedule III authority and a current DEA registration may prescribe buprenorphine for opioid use disorder, subject to the one-time DEA training attestation. As of July 2026.. That opened office-based OUD treatment to solos who previously could not offer it, and it brings a distinct visit pattern: closer follow-up during induction and stabilization, then a longer maintenance cadence — a rhythm that fills a schedule differently than a general medication panel.

The REMS drugs. Certain medications carry a Risk Evaluation and Mitigation Strategy imposing prescriber enrollment, pharmacy participation, and monitoring requirements — clozapine and esketamine among them 4Ref 4U.S. Food and Drug Administration (2026).Risk Evaluation and Mitigation Strategies (REMS).That certain drugs, including clozapine and esketamine, carry REMS programs imposing prescriber enrollment, pharmacy, and monitoring requirements that dictate in-office observation windows and monitoring intervals in the schedule.. These programs dictate slots directly: an in-office observation window, or a monitoring interval that must be met before the next prescription. Clozapine's monitoring, in particular, means arranging labs without a health system behind you, and the cadence of those results structures the follow-up schedule. Long-acting injectables add their own recurring rhythm, since an injection visit under a buy-and-bill arrangement is a calendar event on a fixed interval whether or not anything else about the case has changed.

The invisible load: PDMP checks, prior auths, and paperwork

The billed visits are only part of a prescriber's real workload; a substantial share of the week is unbilled and easy to leave out of a schedule until it overflows. A realistic visit mix budgets time for the work that surrounds prescribing, not just the encounters themselves.

PDMP checks. Every state operates a prescription drug monitoring program, and most mandate a query before prescribing controlled substances, with the specific requirement set state by state 5Ref 5PDMP Training and Technical Assistance Center (2026).Prescription Drug Monitoring Program Training and Technical Assistance Center.That every state operates a PDMP and most mandate a query before prescribing controlled substances, with the specific requirement set state by state — a recurring step on controlled-substance follow-ups.. For a psychiatric practice that prescribes stimulants and other scheduled medications, that is a recurring step attached to a meaningful fraction of follow-ups — small individually, but real in aggregate.

Prior authorizations. Many psychiatric medications trigger a payer prior-authorization step, and in a solo practice the person completing it is usually the prescriber. This is unpredictable, unbilled, and clustered around exactly the medication changes that also demand clinical attention.

The security and compliance floor. The HIPAA Security Rule requires administrative, physical, and technical safeguards for electronic health information, scaled to the size of the practice and anchored in a documented risk analysis 6Ref 6HHS Office for Civil Rights (2026).Summary of the HIPAA Security Rule.That the Security Rule requires administrative, physical, and technical safeguards for electronic health information, scaled to the size of the practice and anchored in a documented risk analysis.. A solo does not need an IT department to meet it: the ONC/OCR Security Risk Assessment tool is built for small practices to work through the analysis themselves 7Ref 7Office of the National Coordinator / ASTP (2026).Security Risk Assessment Tool.That ONC/OCR publish a free Security Risk Assessment tool sized for small practices to conduct the risk analysis the Security Rule requires without an IT department.. Budgeting a few hours for it is part of a schedule that can actually be run, not a task that lives permanently at the bottom of the list.

Payer relations and the measures that reward a follow-up cadence

The visit mix is not only an internal question; it interacts with how payers evaluate a practice. HEDIS is the measure set health plans report, and several of its measures reach directly into outpatient behavioral-health practice patterns — antidepressant medication management and follow-up after an emergency-department visit for mental illness among them 8Ref 8National Committee for Quality Assurance (2026).HEDIS.That HEDIS is the measure set plans report and that measures such as antidepressant medication management and follow-up after an ED visit for mental illness reach into outpatient behavioral-health follow-up patterns.. A schedule that reliably accommodates timely follow-ups performs well on measures like these; one that runs so hot it cannot fit a post-hospitalization visit does not.

This is worth understanding as an alignment rather than a mandate. The follow-up cadence that is good medicine — seeing a patient soon after a medication start, closing the loop after an acute episode — is the same cadence these measures are built to capture. A practice does not have to chase the measures; it has to leave room for the visits the measures are measuring.

For a solo weighing whether to hold panel relationships at all, the measures are one more input into the mix. They reward accessible, continuous care, which argues for a schedule with enough follow-up capacity and enough slack to absorb the urgent post-acute visit rather than pushing it weeks out.

Building a mix that survives you

A visit mix that only works when nothing goes wrong is not sustainable, because in a solo practice the single point of failure is the clinician. A schedule with no slack has no coverage plan, and a panel with no continuity arrangement has no answer for the week the prescriber is unavailable. Building for continuity is part of designing the mix, not a separate project for later.

That means reserving capacity rather than filling every slot: room for the urgent add-on, the crisis follow-up, the case that suddenly needs two visits this week instead of one. It also means having a genuine coverage arrangement for time away and a plan for the records and prescriptions that cannot simply pause. Professional bodies treat these as core practice-management questions — the APA's practice organization publishes guidance on running, covering, and eventually closing a practice, including the professional will that names who steps in if the clinician cannot 9Ref 9APA Services, Inc. (2026).Practice — APA Services.That the APA practice organization publishes practice-management guidance on running, covering, and closing a practice, including the professional will that names who steps in if the clinician becomes unavailable..

The practical test of a visit mix is whether it leaves the prescriber able to take a week off, absorb a bad month, and hand the panel to someone if it ever has to move. A mix tuned only for maximum throughput fails all three. One built with deliberate slack — protected evaluation slots, a predictable follow-up cadence, unbilled time accounted for, and a coverage plan in place — is the one that lasts.
