TL;DR: The Centers for Medicare & Medicaid Services modified NCD 346 covering annual depression screening for Medicare beneficiaries, with a policy review date of 2026-01-09. Here's what billing teams need to know.
The CMS depression screening coverage policy under NCD 346 Medicare has been in place since October 14, 2011, but this review confirms and restates the active coverage rules your team must follow today. The Centers for Medicare & Medicaid Services covers one annual depression screening session, up to 15 minutes, for Medicare beneficiaries in primary care settings — but only when specific staff-assisted care supports are in place. This policy does not list specific CPT or HCPCS codes, so your billing team needs to verify code assignment through your MAC's claims processing instructions.

CMS Depression Screening Coverage Criteria and Medical Necessity Requirements 2026
The CMS depression screening coverage policy is grounded in a USPSTF Grade B recommendation. That rating matters because it triggers the "additional preventive services" benefit category under Medicare Part B. Grade B means the evidence is solid — not experimental, not borderline. CMS covered this from the start because the evidence supported it.
Here's the core medical necessity requirement: the screening must happen in a primary care setting that has staff-assisted depression care supports in place. This isn't optional language. It's the hinge the entire coverage policy swings on. If the supports aren't there, the service isn't covered — regardless of how well the clinician performs the screening itself.
What counts as "staff-assisted supports" at minimum? Clinical staff — a nurse, physician assistant, or equivalent — who can advise the physician of screening results and facilitate referrals to mental health treatment. Your setting doesn't need a full behavioral health integration program. But it does need documented staff involvement in the care pathway. If your practice can't show that, you have a medical necessity problem, not just a documentation problem.
CMS doesn't mandate a specific screening tool. The G-2 screener, the PHQ-9, the PHQ-2 — all are acceptable. The clinician chooses. This is one of the more practical aspects of this coverage policy. You don't need to build your workflow around a particular instrument.
The service covers up to 15 minutes of screening time annually. One screening per 12-month period. That's the ceiling. Prior authorization is not required for this preventive service under Medicare, which keeps the administrative burden low. But the absence of prior authorization requirements doesn't reduce the documentation burden — you still need to show the setting qualifications are met.
Medicare coinsurance and the Part B deductible are waived for this service. That means zero cost-sharing for the beneficiary. Your team should flag this in your patient-facing billing materials, especially for older adult populations where cost is a barrier to care engagement.
CMS Depression Screening Exclusions and Non-Covered Indications
This policy draws clear lines around what it does not cover. Your billing team needs to know these cold, because they're the most likely source of claim denial.
Screening more than once in a 12-month period is not covered. Full stop. If a beneficiary received their annual depression screening in March and the clinician wants to re-screen in September, that second service is not reimbursable under this NCD. It doesn't matter if the patient's clinical situation changed. The frequency limit is firm.
Treatment is not covered under this NCD. Pharmacotherapy, combination therapy (counseling plus medications), and other therapeutic interventions for depression fall outside NCD 346. So does treatment for any disease, complication, or chronic condition that results from depression. This policy covers the screening only — the act of identifying potential depression. What happens after a positive screen is a separate billing matter entirely.
Self-help materials, telephone calls, and web-based counseling are not separately reimbursable under this NCD. Don't try to carve out a billing line for patient handouts or follow-up phone calls under this coverage. Medicare won't pay for them here.
If the service occurs outside a primary care setting, it's not covered. A psychiatrist's office, a hospital inpatient unit, or a specialty clinic without staff-assisted supports in place — none of these qualify under NCD 346. The setting requirement is both a coverage rule and a medical necessity criterion. Document the setting explicitly on the encounter record.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Annual depression screening, up to 15 minutes, in a primary care setting with staff-assisted care supports | Covered | Not specified in NCD — verify with your MAC | One screening per 12-month period; coinsurance and Part B deductible waived |
| Depression screening performed more than once in a 12-month period | Not Covered | — | Frequency limit is firm regardless of clinical circumstances |
| Depression screening in a setting without staff-assisted care supports | Not Covered | — | Setting qualification is a hard coverage requirement |
| Treatment for depression (pharmacotherapy, counseling, combination therapy) | Not Covered under NCD 346 | Separate billing applies | Treatment billed under different benefit categories |
| Self-help materials, phone counseling, web-based counseling | Not Covered | — | Not separately reimbursable under this NCD |
| Screening for complications or chronic conditions resulting from depression | Not Covered under NCD 346 | Separate billing applies | Outside scope of this NCD |
CMS Depression Screening Billing Guidelines and Action Items 2026
The real issue with depression screening billing isn't the annual frequency rule. Most billing teams know that one. The real exposure is the staff-assisted supports requirement — it's vague enough to create gaps, and CMS auditors know it.
Here are your concrete steps:
| # | Action Item |
|---|---|
| 1 | Document staff-assisted supports explicitly on every encounter before billing. Don't assume the existence of a care coordination process counts. Your documentation needs to show that clinical staff were available, reviewed screening results, and could facilitate referrals. If your EHR doesn't have a field for this, add a note in the encounter record before the claim goes out. |
| 2 | Verify the correct HCPCS or CPT code with your Medicare Administrative Contractor before billing. NCD 346 does not list specific procedure codes. This is a genuine gap. Your MAC's claims processing instructions (Transmittal 2359 and Transmittal 2431 are referenced in the NCD) are the definitive source. Check your MAC's website or call their provider relations line. Do this now — not after your first denial. |
| 3 | Set up a 12-month frequency check in your billing system. The one-per-year limit generates preventable claim denials. If your practice management system can track this automatically, configure it. If not, build a manual check into your pre-billing workflow for any depression screening service. |
| 4 | Train front-desk and clinical staff that this service has zero cost-sharing for the patient. Medicare coinsurance and the Part B deductible are waived. If your system automatically calculates a patient liability for this service, that's a billing error. Fix it in your fee schedule setup and in your patient estimate workflow. |
| 5 | Audit your setting qualifications annually. Staff turnover happens. A practice that had a qualifying care coordinator on staff last year may not have one today. Before billing depression screening billing claims, confirm your current staffing model still meets the minimum staff-assisted supports standard. This is especially important for small practices that may have reduced clinical support staff. |
| 6 | Keep treatment billing separate from screening billing. If a positive screen leads to same-day treatment initiation or a behavioral health referral, those services bill under different codes and benefit categories. Don't bundle them under the depression screening service. Doing so creates a claim denial risk and a potential overpayment issue. |
If you're unsure whether your practice setting qualifies under the staff-assisted supports requirement, talk to your compliance officer before the effective date of any upcoming audit cycle. This is the criterion most likely to get scrutinized.

CPT, HCPCS, and ICD-10 Codes for Depression Screening Under NCD 346
The policy data for NCD 346 does not specify applicable CPT, HCPCS Level II, or ICD-10-CM codes directly within the NCD document.
This is not unusual for older NCDs, but it creates a real operational problem for your billing team. You cannot submit a claim without a procedure code, and the NCD itself won't give you one.
How to Find the Right Codes
Your Medicare Administrative Contractor's claims processing instructions are the correct source. CMS published Transmittal 2359 and Transmittal 2431 under the Medicare Claims Processing Manual specifically for this NCD. Those transmittals contain the procedure codes and billing guidelines your team needs. Retrieve them directly from the CMS website or through your MAC's provider portal.
Common practice in the industry has associated G-code billing with annual depression screening for Medicare, but verify the current applicable code with your MAC before submitting. Code assignments can change, and billing the wrong code — even an outdated G code — generates a claim denial that your team then has to work.
Do not assume that because a code has been used historically, it remains valid today. Verify current code assignments before billing depression screening claims in 2026.
