How to Document Behavioral Health Screenings in Primary Care: PHQ-9, GAD-7, and Integrated Care Workflows

Why Behavioral Health Screening Documentation Is Different in Primary Care

Behavioral health screenings happen across virtually every clinical setting, but primary care is where they carry the most documentation complexity. You are often running multiple validated instruments in a single visit, the results have direct billing implications, and a positive screen triggers a documentation chain that spans the initial encounter, any same-day behavioral health consultation, and the follow-up plan. Get any link in that chain wrong and you create audit exposure, lose billable revenue, or leave a clinical gap that matters if the patient later presents in crisis.

The core challenge is that most primary care providers learned documentation for medical problems. The Patient Health Questionnaire-9 (PHQ-9), the Generalized Anxiety Disorder-7 (GAD-7), the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C), and the Columbia Suicide Severity Rating Scale (C-SSRS) are standardized screening instruments with specific scoring systems, defined threshold meanings, and billing codes attached to them. Documenting a PHQ-9 as "patient reports feeling depressed" misses the score, misses the billing opportunity, and provides nothing useful for longitudinal tracking.

This guide covers how to document each major instrument, what a positive screen triggers in your chart, how to document same-day behavioral health consultation and warm handoffs, how to bill correctly under CPT 96127 and related codes, and where documentation errors most often create audit flags.

The Instruments: Scoring, Thresholds, and What to Record

PHQ-9

The PHQ-9 is a nine-item self-report instrument measuring depressive symptom frequency over the past two weeks. Each item is scored 0 to 3 (not at all, several days, more than half the days, nearly every day), yielding a total score from 0 to 27.

Scoring thresholds:

• 1 to 4: Minimal depression
• 5 to 9: Mild depression
• 10 to 14: Moderate depression
• 15 to 19: Moderately severe depression
• 20 to 27: Severe depression

What to document beyond the score:

The total score is the minimum. A complete PHQ-9 documentation entry should also include the administration date, who administered the instrument (clinical staff, self-administered in waiting room, via patient portal), and the patient's response to item 9 (suicidal ideation question, scored separately). Item 9 warrants specific documentation regardless of the total score because a score of 1 or higher on that item triggers a separate clinical and documentation obligation even if the total score is in the mild range.

Example documentation: "PHQ-9 administered by clinical staff on 2026-04-01. Total score: 13 (moderate depression range). Item 9 (suicidal ideation): 1 (several days). Patient endorses passive ideation without intent or plan. Safety assessment conducted (see below). Positive screen discussed with patient; same-day BHC consult arranged."

GAD-7

The GAD-7 is a seven-item instrument measuring anxiety symptom frequency over the past two weeks. Items are scored 0 to 3, with a maximum score of 21.

Scoring thresholds:

• 0 to 4: Minimal anxiety
• 5 to 9: Mild anxiety
• 10 to 14: Moderate anxiety
• 15 to 21: Severe anxiety

What to document beyond the score:

The administration date, method, and total score. For scores of 10 or above, document whether the patient was informed of the result, what clinical action was taken, and whether a follow-up plan was established. GAD-7 and PHQ-9 are frequently co-administered in primary care because depression and anxiety often co-occur. When both are administered in the same visit, document both scores as separate entries rather than combining them into a single line.

Example documentation: "GAD-7 administered by clinical staff on 2026-04-01. Total score: 11 (moderate anxiety range). Patient also completed PHQ-9 (score 13, documented separately). Both results reviewed with patient. BHC consult requested same-day."

AUDIT-C

The AUDIT-C is a three-item abbreviated version of the full Alcohol Use Disorders Identification Test. It screens for hazardous or harmful alcohol use. Scoring differs by sex: a score of 4 or higher in men, or 3 or higher in women, is considered a positive screen.

What to document:

Total score and the sex-specific threshold used to interpret it. If positive, document whether a brief intervention (BI) was provided in the visit. Payers auditing substance use screening documentation look for evidence that a positive screen was followed by a clinical response, not just noted.

Example documentation: "AUDIT-C administered on 2026-04-01. Patient: female. Total score: 4 (positive screen, threshold 3 for female patients). Brief alcohol use counseling provided during visit, approximately 5 minutes. Patient provided with written materials on safer drinking guidelines. Patient agrees to reassessment at next visit."

Columbia Suicide Severity Rating Scale (C-SSRS)

The C-SSRS is a structured suicidality assessment instrument used both as a screening tool and as a more comprehensive assessment when a patient has endorsed suicidal ideation. In primary care, it is most commonly used in one of two contexts: as a screener following a positive PHQ-9 item 9, or as a baseline tool for patients with known psychiatric diagnoses.

What to document:

The C-SSRS has two primary dimensions: ideation (rated 1 to 5 on type and severity of ideation) and behavior (presence of any suicidal behavior in the past or defined timeframe). Document both dimensions. Also document the clinical context prompting the screening and the clinical response to the result.

Example documentation: "C-SSRS administered following PHQ-9 item 9 endorsement (score 1). Ideation subscale: 1 (wish to be dead, without active ideation). Behavior subscale: no prior attempts or preparatory behavior. Risk level assessed as low based on absence of active plan or intent. Safety plan discussed and documented separately. Patient agrees to follow up with BHC within one week."

Documenting a Positive Screen: The Follow-Up Chain

A positive screen result is not a complete documentation entry by itself. What happens after a positive result is where most documentation gaps occur, and where audit exposure is highest.

When a screening instrument returns a positive result, your note should capture four things:

1. The score and threshold interpretation. State the numeric score and what clinical range it falls in. Do not leave an auditor to calculate or infer the interpretation.

2. Whether and how the result was disclosed to the patient. Patients have the right to know their screening results. Document that the result was reviewed with the patient and their reaction or understanding.

3. The clinical response. This is the most commonly missing element. A positive PHQ-9 score of 13 requires a clinical response: a same-day behavioral health consultation, a referral with a documented timeframe, a prescription initiation with follow-up, or a documented clinical rationale for watchful waiting. The absence of a documented clinical response to a moderate-range positive screen creates both a patient safety gap and an audit vulnerability.

4. The follow-up plan. What happens next, and when. If the patient was referred to a behavioral health provider, document the referral destination, the urgency level, and the expected timeframe. If a same-day consult occurred, document it (see the warm handoff section below).

Example: Positive PHQ-9 follow-up documentation block

"PHQ-9 score of 13 (moderate range) reviewed with patient J.M. (DOB: 1985-06-22) on 2026-04-01. Patient acknowledges results and reports symptoms consistent with her reported sleep disruption, low energy, and decreased concentration over the past 6 weeks. PHQ-9 item 9: 0 (no suicidal ideation). BHC Maria Solano, LCSW consulted same-day via warm handoff; consult note from BHC attached. PCP follow-up scheduled in 4 weeks. Patient provided with psychoeducation on depression and handout on community mental health resources."

Integrated Care Workflows: Same-Day BHC Consultation

In a primary care behavioral health integration (PCBHI) model, a behavioral health consultant (BHC) is embedded in the primary care practice and available for same-day consultations, typically brief (15 to 30 minutes) and focused on functional behavioral health concerns.

When a positive screen triggers a same-day BHC consult, both the PCP and the BHC document. The documentation is not duplicative: the PCP's note captures the screening result, the clinical reason for the consult, and the overall encounter. The BHC's note captures the consultation itself.

What the PCP documents when referring for a same-day BHC consult

• The screening score and positive screen determination
• The clinical indication for same-day consultation (positive score plus patient preference plus clinical judgment)
• The patient's consent to the consultation
• The BHC's name and role
• That the consult occurred and that a BHC note is in the chart (or forthcoming)
• Any changes to the overall treatment plan that resulted from the consult

What the BHC documents in the consultation note

The BHC consultation note in a PCBHI model typically follows a structured format:

• Referral reason: Brief description of why the PCP referred and what the screening showed
• Patient self-report: What the patient describes as the presenting concern, in behavioral and functional terms (not diagnostic language for a brief consult)
• Behavioral observations: Brief note on engagement, affect, and communication
• Functional assessment: How the presenting concern is affecting the patient's daily functioning (work, relationships, sleep, health behaviors)
• Behavioral health formulation: Brief clinical impression
• Intervention during consult: What was done in this 15 to 30 minute contact
• Recommendations to PCP: Specific, actionable (not "consider therapy" but "recommend 6-session CBT-based brief therapy with me, starting next week")
• Patient agreement and next steps

The BHC note does not need to replicate the PCP's screening documentation. The two notes together create the complete clinical picture.

Example BHC consultation note (brief primary care format)

"BHC Consultation Note, 2026-04-01. Referral: Dr. Nguyen, PHQ-9 = 13, initial assessment for depression management. Patient J.M., 40-year-old female, referred for brief BHC consult following positive depression screen. Patient describes 6-week onset of low mood, disrupted sleep (early waking), fatigue, and difficulty concentrating at work. Attributes onset to workplace restructuring and increased caregiver responsibilities for parent with dementia.

Functional impact: missing approximately 2 days per week of effective work performance. Social withdrawal from peer group. No current suicidal ideation. PHQ-9 item 9 = 0 confirmed with patient.

Behavioral observations: Patient engaged and forthcoming. Affect flat but reactive. No psychotic or manic features. Motivated for behavioral strategies.

Formulation: Depressive episode, moderate severity, situationally triggered with functional impairment. Good prognostic indicators: insight, motivation, intact support structure.

Intervention: Psychoeducation on depression and behavioral activation. Initial behavioral activation goal set: one social contact per week with named friend. Sleep hygiene reviewed.

Recommendations to PCP: 1) Brief CBT-based intervention (4 to 6 sessions with this BHC, starting 2026-04-08). 2) Consider pharmacotherapy if no functional improvement in 4 weeks. 3) Reassess PHQ-9 at 4-week PCP follow-up. Patient agrees. Follow-up BHC appointment scheduled."

Warm Handoff Documentation

A warm handoff is a structured, in-person (or synchronous telehealth) introduction between the PCP, the patient, and the BHC that occurs within the same clinical encounter. It is more than a referral: it is an active transfer of care that is documented differently.

What distinguishes warm handoff documentation from a standard referral:

• The PCP documents that the handoff occurred in real time, not as a future referral
• The BHC documentation reflects that the patient arrived through a warm handoff and the context that was communicated
• The time of the handoff is often relevant if billing 96127 alongside the office visit

PCP warm handoff documentation example:

"Following positive PHQ-9 (score 13), warm handoff to BHC Maria Solano completed at 11:45 AM. Patient was introduced to Ms. Solano in person and consented to brief same-day consultation. PCP communicated PHQ-9 result, chief complaint, and relevant social history to BHC in patient's presence. BHC consultation note to be added to chart same day."

Billing Documentation: CPT 96127 and G-Codes

CPT 96127: Brief Emotional and Behavioral Assessment

CPT 96127 is the code for administering and scoring a standardized behavioral health screening instrument. It applies per instrument administered, meaning if you administer both a PHQ-9 and a GAD-7 in the same visit, you can bill two units of 96127.

Documentation requirements for 96127:

• The specific instrument administered (PHQ-9, GAD-7, AUDIT-C, C-SSRS, or other standardized validated tool)
• The total score
• The clinical interpretation (mild, moderate, severe, or equivalent clinical language)
• Evidence that a provider reviewed the results (not just that staff administered the instrument)

The provider review requirement is where many practices fail audit. If a medical assistant administers the PHQ-9 and no provider documentation acknowledges the result, the 96127 claim is at risk. The reviewing provider's name should appear in the documentation for each instrument scored.

Common billing documentation error for 96127: Documenting "PHQ-9 administered, results reviewed" without the numeric score or clinical interpretation in the note. Some EHRs autopopulate screening scores in a separate flowsheet but not in the encounter note. For billing purposes, the score needs to be in a place where an auditor reviewing the encounter note can find it.

G-Codes for Behavioral Health Integration

If your practice is operating under a Behavioral Health Integration (BHI) model (not the full CoCM model, but the simpler general BHI model), relevant G-codes include:

• G0444: Annual depression screening, 15 minutes. Requires documentation that a standardized screening tool was used and that results were reviewed and acted upon by the billing provider.
• G0442/G0443: Alcohol misuse screening and brief counseling. G0442 covers the screening, G0443 covers the brief counseling intervention (15 minutes). These require documentation of the AUDIT-C or equivalent score and evidence that the counseling intervention actually occurred.

Documentation for G-codes follows the same logic as 96127: the score must be in the chart, the provider must have reviewed it, and if a clinical action was taken (counseling, referral, follow-up plan), that action must be documented.

Common Documentation Errors That Create Audit Flags

Screening score in the flowsheet only, not in the encounter note. Many EHRs have separate screening flowsheets where staff record PHQ-9 and GAD-7 results. If the encounter note does not reference the score or contains only a generic line like "depression screening performed," an auditor reviewing the note cannot verify the billing was supported. Link the flowsheet score to the encounter note explicitly.

No provider review documented for staff-administered screenings. A medical assistant or front desk staff can hand a patient a PHQ-9 on a tablet. The score cannot be billed under 96127 unless a provider reviewed and interpreted the result. Document this review, including the provider's name and a brief clinical interpretation, in the encounter note.

Positive screen with no documented clinical response. This is both a documentation error and a patient safety gap. If a PHQ-9 score of 15 appears in the chart and the encounter note contains no reference to it, the documentation suggests the result was ignored. Every positive screen at moderate severity or above needs a documented clinical response, even if that response is watchful waiting with a clinical rationale.

Suicidality item 9 endorsed without a specific documentation entry. A PHQ-9 item 9 score of 1 or higher requires separate documentation. Do not fold it into the total score entry and move on. Document the specific item 9 score, the follow-up assessment that occurred, the risk determination, and the plan.

Co-administered instruments billed as a single unit of 96127. If you administered a PHQ-9 and a GAD-7 in the same visit, that is two units of 96127, and both should be documented separately with their own scores and interpretations. A single combined line is ambiguous at billing time.

Warm handoff documented only in the BHC's note. If the PCP's note does not reference that a warm handoff occurred, the integrated care workflow is not visible from the encounter note. Both clinicians document their part.

G0444 billed without evidence the provider acted on the result. Annual depression screening under G0444 requires that the result was reviewed and that something happened: a referral, a brief counseling interaction, a follow-up scheduled, or a documented clinical rationale for no intervention. "Depression screen performed, negative" is sufficient for a negative result. A positive result needs a documented response.

Using Templates to Keep Screening Documentation Consistent

The most reliable way to avoid the documentation errors described above is to build them out of your workflow structurally. When the template for every primary care encounter includes a screening documentation block with fields for instrument name, date, total score, item-specific flags, provider review attestation, and clinical response, providers are prompted to complete each element rather than remembering to add it.

NotuDocs lets you build primary care visit templates that include these screening documentation blocks as required fields, so the completed note automatically contains what 96127 and G-code billing requires. The template structure means new staff or covering providers document screening results the same way as experienced clinicians, which matters for practices managing audit risk across multiple providers.
