Summary & Overview
HCPCS G9818: Documentation of Sexual Activity
HCPCS Level II code G9818 denotes documentation of sexual activity in the patient record, signifying that sexual history or related behaviors were reviewed and recorded during an encounter. Nationally, consistent documentation of sexual activity supports preventive care, risk assessment for sexually transmitted infections, reproductive planning, and appropriate screening. Clear use of G9818 can standardize reporting of these clinical actions across settings.
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 purpose, typical service settings, and implications for billing workflows. The publication outlines documentation benchmarks where available, common modifiers associated with outpatient services, and the policy context that affects coverage and reporting for sexual history documentation. The summary also provides practical context for clinicians and administrators on where G9818 fits within preventive and sexual health services and what to expect when reconciling documentation with billing and compliance processes.

Clinical & Coding Specifications
Clinical Context
A 28-year-old sexually active female presents to a primary care clinic for a routine preventive visit and reports recent changes in sexual practices and partners. The clinician obtains a focused sexual history, documenting the onset of sexual activity, number of partners, contraceptive use, condom use, sexual orientation, practices that may increase STI risk, and any symptoms such as pain with intercourse or abnormal discharge. The documentation of sexual activity is recorded in the medical record to inform risk assessment, screening decisions (for example, nucleic acid amplification testing for chlamydia/gonorrhea, HIV screening), contraception counseling, and immunization status (such as HPV vaccination). Typical workflow: registration and intake include standardized screening questions; the clinician conducts a confidential interview in the exam room, documents the sexual history in the EHR using structured fields and narrative text; appropriate orders (labs, vaccination) are placed and patient education materials are provided. Typical site of service: outpatient clinic or ambulatory care setting, including family medicine, internal medicine, obstetrics/gynecology, and sexual health clinics.
