CPT 99408: Screening and Brief Intervention for Substance Misuse (15–30 min)
CPT code 99408 represents a targeted behavioral health service: a combined screening and brief intervention for alcohol or other non‑tobacco substance misuse lasting 15–30 minutes. This code is used nationally across outpatient and office‑based settings to document time‑based counseling aimed at early identification and intervention for risky substance use. Its use matters because brief interventions are linked to population‑level reductions in substance use harms and are increasingly incorporated into primary care and integrated behavioral health models.
Key payers in national coverage discussions include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context for the service, typical sites of care where the code is billed, common modifiers and operational considerations, and how this code relates to other time‑based behavioral health services. The publication summarizes payment and policy considerations relevant to payers listed above and outlines benchmarks and reporting implications when available. Data not available in the input are noted where applicable.
