Summary & Overview
HCPCS G8511: Positive Depression Screening, No Follow-Up Documented
HCPCS Level II code G8511 identifies encounters where a depression screening is documented as positive but a follow-up plan is not recorded and no reason is provided. This code matters nationally as depression screening and appropriate follow-up are central to quality measurement, continuity of care, and payer compliance programs. Documentation gaps captured by G8511 can affect quality metrics, performance reporting, and care coordination efforts across outpatient and primary care settings.
Key payers addressed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of the clinical context for depression screening, how G8511 is used in practice, and the implications for quality measurement and documentation workflows. The publication summarizes common billing modifiers and the typical service settings where the code appears, highlights documentation priorities tied to the code, and outlines what to expect in payer coverage and claims review processes.
The report does not provide clinical recommendations but supplies concise benchmarking context, policy considerations, and operational details relevant to clinicians, coding professionals, and payer auditors.

Clinical & Coding Specifications
Clinical Context
A middle-aged adult presents to a primary care clinic for an annual wellness visit. During the visit the clinician administers a validated depression screening tool (for example, PHQ-9). The patient’s screening result is documented as positive for depression symptoms. The medical record documents the positive screen but does not document a follow-up plan (no safety assessment, no treatment discussion, no referral, and no plan for monitoring) and no reason is recorded for why a follow-up plan was not documented. Typical workflow includes screening by nursing staff, review of results by the clinician, documentation in the electronic health record, and initiation of a follow-up plan when indicated; in this scenario the documentation stops at the positive screen without a subsequent plan. Typical site of service is an outpatient office or clinic during preventive or problem-focused visits. Common patient presentations include new depressive symptoms, exacerbation of chronic mood disorder, or screening during preventive care.
