Depression screening is a required component of the Medicare Annual Wellness Visit (AWV): the visit's health risk assessment must review the patient's risk factors for depression, and most practices operationalize this with a validated tool like the PHQ-2 or PHQ-9. Medicare also covers a separate annual depression screening under code G0444. The requirement is easy to meet on paper — the harder part is what happens after a positive screen.

For a condition this common and this treatable, the AWV is one of the few moments in a year when nearly every older adult sits down with their primary care team. That makes it a natural checkpoint for depression — and a revealing one, because it exposes the gap between screening and doing something with the result.

What does the Annual Wellness Visit require for depression?

The AWV is a Medicare benefit — distinct from a physical exam — built around a Health Risk Assessment (HRA) and a personalized prevention plan. Reviewing the patient's risk factors for depression is one of the HRA's defined elements. The AWV rules describe the requirement in terms of screening for depression risk; they do not mandate one specific instrument.

In practice, most primary care teams satisfy this with a standardized questionnaire rather than an open-ended question, because a structured tool is more sensitive and more auditable. The two most common choices:

• PHQ-2 — a two-item screen used as a first pass. A negative PHQ-2 typically ends the screen; a positive one triggers the fuller tool.
• PHQ-9 — the nine-item Patient Health Questionnaire, which grades severity and includes an item on self-harm. Many practices go straight to the PHQ-9, or step up to it after a positive PHQ-2.

The GAD-7 for anxiety often rides alongside depression screening, though it sits outside the AWV depression requirement itself.

How is depression screening in the AWV paid for?

Two related but separate mechanisms are worth keeping straight, and coverage details change, so confirm current rules with your Medicare Administrative Contractor or payer before you build a billing workflow around them.

As part of the AWV. The initial AWV (commonly billed as G0438) and subsequent AWV (G0439) already include the depression-risk review inside the visit. When screening is done as a component of the AWV, it is generally not billed as a separate line item on the same date — it is part of the service.

As a standalone service — G0444. Medicare separately covers an annual screening for depression, up to 15 minutes, under G0444, in a setting with staff-assisted follow-up available. Historically this code has had timing rules relative to the AWV — for example, it has not typically been separately payable on the same day as the *initial* AWV, since screening is already bundled there, while pairing it with a *subsequent* AWV has been treated differently. These edits get updated, so treat the specifics as something to verify, not assume.

The operational takeaway is simpler than the code detail: screening is covered, and the reimbursement exists. Practices leave value on the table not by miscoding, but by not screening consistently or not acting on positives.

Why does screening happen but follow-up doesn't?

This is the failure mode that matters. A practice can hit a high screening rate and still change nothing for the patient — because the two hardest steps come *after* the questionnaire is scored.

The national clinical guidance is explicit that screening is only recommended when systems are in place to ensure accurate diagnosis, effective treatment, and follow-up. A PHQ-9 of 15 with no next step is not care; it is a documented, unaddressed risk. Yet the gap shows up constantly:

• The score is captured but not surfaced. The number lands in a form field or a flowsheet, and no one is accountable for reviewing positives before the patient leaves.
• A positive screen produces a referral, and the referral goes nowhere. A large share of patients referred out to specialty behavioral health never complete the first appointment. The loop is opened and never closed.
• There's no re-measurement. Depression treatment works when it is adjusted based on whether symptoms actually improve. A single baseline PHQ-9 with no repeat score can't tell anyone whether the plan is working.
• The item-9 (self-harm) response isn't triaged in real time. A positive safety item needs a same-visit protocol, not a callback next week.

Screening is the cheap part. The expensive, higher-value part is the system that turns a positive score into diagnosis, treatment, and measured follow-up.

What does "closing the loop" actually look like?

Closing the loop means every positive screen has an owner and a defined next step, and the patient's symptoms get re-measured over time. Concretely, a practice that does this well has:

• A protocol for what happens when a PHQ-2 or PHQ-9 crosses threshold — before the patient walks out.
• A same-day pathway for a positive self-harm item.
• Someone accountable for follow-up contact, not just a referral fired into a fax queue.
• Repeat PHQ-9 scoring on a schedule, so treatment can be adjusted when the number isn't moving.

This is precisely the structure the Collaborative Care Model (CoCM) was built to provide. CoCM — the most heavily studied model of behavioral health integration, with a large randomized-trial evidence base — wraps a behavioral health care manager and a consulting psychiatrist around the primary care team. It is measurement-based by design: PHQ-9 scores are tracked over time, and the plan changes when patients aren't improving. Screening in the AWV creates the signal; a model like CoCM is what acts on it. Medicare, and in some states Medicaid, cover collaborative care through established billing codes.

How should a practice fit depression screening into the AWV workflow?

A workable pattern, framed as an operational sequence rather than clinical advice:

1. Administer the tool before or at the start of the visit — often a PHQ-2, stepping up to the PHQ-9 on a positive, so scoring is done by the time the clinician sits down. 2. Score it into a discrete field, not free text, so positives can be flagged and reported. 3. Define the threshold and the owner for acting on a positive result during the same visit. 4. Confirm coverage and coding for how you're capturing the screen — inside the AWV versus as a separate G0444 service — against current payer rules. 5. Schedule the follow-up and the re-screen, so a baseline score becomes a trend rather than a one-time data point.

The screening instrument is the easy 10% of this. The workflow around it is the 90% that determines whether it helps anyone.

Frequently asked questions

Is depression screening required at the Medicare Annual Wellness Visit?

Reviewing the patient's risk factors for depression is a defined element of the AWV Health Risk Assessment. Medicare describes it as a screening requirement rather than mandating a specific tool, so most practices use a validated instrument like the PHQ-2 or PHQ-9 to meet it consistently.

What is code G0444?

G0444 is Medicare's code for an annual depression screening of up to 15 minutes in a setting with staff-assisted follow-up available. It is separate from the AWV codes, and it has historically carried timing rules relative to the AWV. Confirm current billing edits with your payer, since these change.

PHQ-2 or PHQ-9 — which should a practice use?

Many practices use the PHQ-2 as a quick first pass and step up to the PHQ-9 when it's positive, since the PHQ-9 grades severity and includes a self-harm item. Others administer the PHQ-9 directly. Either approach can satisfy the screening requirement; the PHQ-9 adds the severity tracking that follow-up depends on.

What happens after a positive depression screen?

A positive screen should trigger diagnostic follow-up, a treatment decision, and a plan to re-measure symptoms over time — with a same-visit pathway for any positive self-harm response. Screening is only recommended where these follow-up systems exist. Capturing the score without acting on it is the most common failure.

Does a high screening rate mean depression is being managed?

Not by itself. A screening rate measures how often the questionnaire is administered, not whether positives led to diagnosis, treatment, and improvement. The meaningful measure is whether patients who screen positive get connected to care and see their scores come down.
