HCPCS G9745: Documented Reason for Not Screening or Recommending Follow-Up for High Blood Pressure

HCPCS Level II code G9745 is used to document a clinician’s reason for not performing or not recommending follow-up for high blood pressure. As a discrete, reportable encounter-level code, G9745 records a documented clinical decision to defer screening or ongoing management of elevated blood pressure, creating an auditable element in the medical record and supporting quality reporting and administrative review. Nationally, adoption of this code matters for accurate quality measurement, clinical workflow documentation, and payer adjudication of blood pressure–related measures.

Key payers addressed in this publication include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the code’s clinical context, expected sites of service, and implications for clinical documentation. The publication also outlines common reporting practices and what to look for in payer policies and quality programs. Where input data is lacking, the text notes that specific crosswalks to diagnoses, taxonomies, or related codes are not provided.

This analysis is written for a national audience and focuses on how G9745 functions within clinical documentation and quality reporting for hypertension screening and follow-up decisions. It is intended to inform billing, compliance, and clinical staff about the purpose and operational use of the code rather than provide clinical guidance.

Billing Code Overview

HCPCS Level II code G9745 documents a clinician-documented reason for not screening or not recommending a follow-up for high blood pressure. This code indicates that a decision was made to defer blood pressure screening or follow-up based on a documented rationale in the patient record.

Service type: Clinical documentation of decision-making regarding blood pressure screening or follow-up
Typical site of service: Outpatient clinic or ambulatory care setting where blood pressure screening decisions are made

Clinical & Coding Specifications

Clinical Context

A 58-year-old male presents to a primary care clinic for an annual wellness visit. During vitals, blood pressure readings are elevated (e.g., 152/94 mmHg) on a single in-office measurement. The clinician reviews the patient’s chart, recent home blood pressure logs, current medications, and comorbidities (type 2 diabetes, chronic kidney disease stage 2). After discussion, the clinician documents a reason for not performing initial hypertension screening or not recommending a specific follow-up plan: for example, the patient is actively engaged in home monitoring with recent validated readings within goals, the office measurement is believed to be an isolated situational elevation, the patient refused additional testing or follow-up at that time, or there are concurrent acute medical issues that take precedence.

Typical workflow: patient check-in and vitals → nurse documents blood pressure reading → clinician reviews history and prior readings → shared decision-making discussion with patient → clinician documents the clinical rationale for not screening further or not recommending follow-up for high blood pressure in the medical record and applies billing code G9745 to capture the documented reason. Typical site of service: outpatient primary care clinic, preventive medicine visit, or ambulatory care setting. Typical patient scenario: adult with a prior diagnosis or risk for hypertension where an office reading is elevated but the clinician documents a valid reason for deferring screening or follow-up recommendations (patient preference, confirmed home control, acute competing diagnosis, or measurement artifact).

CPT Code	Description	Relationship to This Procedure
`99213`	Office or other outpatient visit for the evaluation and management of an established patient, typically 15 minutes	Common visit code used when BP is assessed and a rationale for not recommending follow-up is documented during an E/M visit.
`99214`	Office or other outpatient visit for the evaluation and management of an established patient, typically 25 minutes	Used when visit complexity is higher due to comorbidities or extended counseling about BP management and documentation justifies higher-level E/M.
`99406`	Smoking and tobacco use cessation counseling, intermediate, greater than 3 minutes up to 10 minutes	Often provided in the same visit when counseling on cardiovascular risk factors accompanies BP discussion.
