Summary & Overview
HCPCS G8751: Smoking Status and Secondhand Smoke Not Assessed
HCPCS Level II code G8751 captures instances where a patient’s smoking status and household exposure to secondhand smoke were not assessed and no reason for omission was recorded. Nationally, accurate documentation of tobacco use and secondhand smoke exposure is a key quality and public health measure tied to preventive care metrics and population health reporting. This code is used to signal a missed assessment opportunity and may be relevant for quality measurement, chart audits, and care coordination reviews.
Key payers in scope for typical reporting and coverage considerations include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication outlines how G8751 is used in clinical documentation, its implications for quality measurement, and the contexts in which it commonly appears (primary care and preventive visits).
Readers will find an overview of the code’s clinical context, the typical service setting, and an explanation of why documentation matters for public health reporting and quality programs. The report also describes common related administrative workflows and identifies gaps where data was not provided in the input. Data not available in the input will be noted where applicable.

Clinical & Coding Specifications
Clinical Context
A primary care nurse enters the home visit electronic health record after completing a routine adult chronic care visit. The clinician is asked to document the patient’s tobacco use and household exposure to secondhand smoke. The patient is an adult with COPD who receives home-based primary care and is seen for medication management. During the structured social history portion of the visit the clinician does not assess smoking status or household secondhand smoke exposure and provides no reason for omission. The billing staff codes the encounter with G8751 to indicate that smoking status and exposure to second hand smoke in the home were not assessed and no reason was given. Typical workflow includes: intake review of past tobacco status, attempt to obtain current smoking/exposure information from the patient or caregiver, documentation in the problem list and social history, and billing with G8751 only when assessment is not completed and no justification is documented.
