Summary & Overview
HCPCS G9605: Patient Survey Score No Improvement After Treatment
HCPCS Level II code G9605 captures instances where a patient-reported survey score shows no improvement from baseline after treatment. Nationally, such outcome codes inform quality measurement, value-based payment models, and program evaluation by signaling when interventions did not yield measurable patient-perceived benefit. The code applies across outpatient clinical settings where standardized patient surveys are used as part of care assessment.
Key payers included in this review are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The analysis outlines what the code represents, how payers typically regard outcome-reporting codes, and the contexts in which G9605 is submitted on claims or encounter records.
Readers will find a concise explanation of the code’s clinical meaning and service context, benchmarks and reporting implications where available, and relevant policy considerations affecting outcome-based reporting. The summary clarifies what elements are available in the input and notes when specific data points are not provided. This content is written for a national audience interested in quality measurement, billing compliance, and program reporting tied to patient-reported outcomes.
Billing Code Overview
HCPCS Level II code G9605 denotes Patient survey score did not improve from baseline following treatment. This code is used to indicate that a standardized patient-reported outcome or satisfaction survey showed no measurable improvement after an episode of care.
-
Service type: Outcome assessment / patient-reported outcome measurement

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult receiving a therapeutic intervention for a chronic symptomatic condition (for example, chronic low back pain, osteoarthritis, or major depressive disorder) where validated patient-reported outcome measures are used to track response. The patient completes a baseline survey (for example, Oswestry Disability Index, WOMAC, PHQ-9) before treatment and a follow-up survey after a defined treatment interval. The clinical workflow includes: enrollment and baseline survey administration, initiation of treatment (pharmacologic, interventional, physical therapy, behavioral therapy, or device-based), follow-up survey collection at the pre-specified interval, scoring and documentation of the survey, and determination that the patient survey score did not improve from baseline despite completed treatment. Documentation in the medical record includes the instrument name, baseline and follow-up scores, dates of administration, treatment rendered, and clinician interpretation of lack of improvement. Typical site of service is outpatient clinic or ambulatory care (including specialty pain, orthopedics, rheumatology, behavioral health clinics) and may include hospital outpatient departments. The typical patient scenario involves routine outcome measurement tied to quality reporting, programmatic monitoring, or payer reporting where non-improvement is reported using code G9605.
