Summary & Overview
HCPCS G9195: Major Depression Without Antidepressant During 180-Day Continuation Phase
HCPCS Level II code G9195 flags patients with a diagnosis of major depression who lack documentation of antidepressant treatment during the entire 180-day continuation phase. This quality-related code captures gaps in pharmacologic continuation for major depressive disorder and is relevant to clinicians, payers, and quality reporting programs focused on behavioral health continuity of care. Nationally, monitoring continuation-phase antidepressant treatment matters because sustained pharmacotherapy is a common component of evidence-based depression management and influences outcomes and utilization.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the code’s clinical meaning, the types of services and sites where the measure applies, and what to expect in payer coverage contexts. The publication also outlines benchmarking and reporting implications, ties to quality measurement during the 6-month continuation phase, and contextual policy considerations affecting national behavioral health quality programs.
This summary is intended to inform administrators, coders, and policy professionals about the code’s purpose and where it fits in quality and reporting workflows. Data not available in the input will be noted where relevant in the full publication.
Billing Code Overview
HCPCS Level II code G9195 indicates a patient diagnosed with major depression who was not documented as being treated with antidepressant medication during the entire 180-day (6 months) continuation treatment phase. This code reflects a measure of medication continuation and adherence for individuals with major depressive disorder.
-
Service type: Measurement of behavioral health medication management and care continuity during the continuation phase of depression treatment
-
Typical site of service: Outpatient behavioral health settings, primary care clinics, and other ambulatory care environments where depression treatment and follow-up are managed

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult diagnosed with major depressive disorder who completed the acute treatment phase and has entered the 180-day continuation treatment phase. The patient presents for routine follow-up visits over the six-month continuation period and has documentation confirming ongoing psychotherapy or monitoring, but there is no documentation that an antidepressant medication was prescribed, dispensed, or taken during the entire 180-day window. The clinical workflow includes initial psychiatric assessment and confirmation of diagnosis, establishment of a treatment plan (which ordinarily includes pharmacotherapy), scheduling of periodic follow-up visits (in-person or telehealth) to monitor symptoms and adherence, medication reconciliation at each visit, and documentation of medications in the electronic health record. During chart review or quality measure abstraction, the absence of any antidepressant prescription, refill, or patient-reported adherence across the full 180 days triggers the G9195 billing code indicator for “major depression not documented as being treated with antidepressant medication during the entire 180 day continuation treatment phase.”
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
25 | Significant, separately identifiable evaluation and management service by the same physician on the same day of the procedure or other service | Use when a significant E/M visit addressing depression occurs on same day as another non-related service |
59 | Distinct procedural service | Use when services on same day are distinct and should be reported separately from quality measure–related visits |
76 | Repeat procedure or service by same physician | Use if a same-day service is repeated after an earlier one |
77 | Repeat procedure by another physician | Use if another clinician repeats the same service |
91 | Repeat clinical diagnostic laboratory test | Not commonly used for this measure; use when repeat lab testing (e.g., drug levels) is performed |
GQ | Via asynchronous telecommunication system | Use for qualifying telehealth interactions that are asynchronous and affect treatment documentation |
GT | Via interactive audio and video telecommunication | Use for synchronous telehealth visits documenting treatment decisions |
95 | Synchronous telemedicine service rendered via real-time interactive audio and video | Alternate telehealth modifier for real-time visits documenting medication management |
XE | Separate encounter, a service that is distinct because it occurred during a separate encounter | Use when documentation supports a separate encounter relevant to treatment status |
XP | Separate practitioner, a service that is distinct because it was performed by a different practitioner | Use when another practitioner documents medication status separately |
XS | Separate structure, a service that is distinct because it was performed on a separate anatomical site or organ system | Rarely applicable; use only if distinct structure documentation applies |
RT | Right side | Not applicable to this measure; included only when laterality coding is required for paired procedures |
LT | Left side | Not applicable to this measure; included only when laterality coding is required for paired procedures |
CQ | Service provided under arrangement by a CRNA | Use when advanced practice clinician arrangement affects documentation responsibilities |
| Taxonomy Code | Specialty | Notes |
