Summary & Overview

HCPCS G9406: Clinician-Documented Reason 7-Day Post-Discharge Follow-Up Not Completed

HCPCS Level II code G9406 records a clinician-documented reason why a patient did not complete the recommended 7-day follow-up after discharge from an acute inpatient stay. The code captures circumstances such as patient death before the appointment or patient non-compliance that prevented timely post-discharge contact. Nationally, accurate use of G9406 supports care transition documentation, quality measurement, and claims adjudication for post-discharge follow-up performance.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of the code’s clinical context, typical use cases in acute-to-outpatient transitions, and the administrative implications for billing and quality reporting. The publication outlines benchmark considerations, common modifier usage (listed separately), and areas where documentation aligns with payer expectations.

This summary is written for a national audience and focuses on the code’s purpose, typical site of service, and the types of documentation events it is intended to record. Data not available in the input is noted where applicable in supporting sections.

Billing Code Overview

HCPCS Level II code G9406 documents a clinician-recorded reason why a patient was not able to complete a 7-day follow-up after discharge from an acute inpatient setting. Typical reasons include events such as patient death prior to the follow-up visit or patient non-compliance preventing the visit.

Service type: Post-discharge follow-up documentation
Typical site of service: Acute care hospital discharge transition to outpatient or home-based follow-up

Clinical & Coding Specifications

Clinical Context

A typical patient scenario involves a clinician documenting why a patient discharged from an acute inpatient stay did not complete a required follow-up within seven days. For example, a 78-year-old patient hospitalized for acute congestive heart failure is discharged home with instructions for a post-discharge visit within seven days. During outreach, the clinician documents that the patient died at home three days after discharge, and a note is entered citing death prior to follow-up. In another scenario, a patient is discharged after a surgical admission and declines the scheduled outpatient follow-up visit due to transportation barriers and refusal; the clinician documents patient non-compliance and the circumstances. The clinical workflow includes discharge planning, scheduling a follow-up appointment, post-discharge outreach (phone call or electronic message), documentation of barriers or events preventing the visit (e.g., death, hospice transfer, patient refusal, hospitalization readmission), and use of the specific HCPCS Level II code G9406 to indicate a documented reason for failure to complete the seven-day follow-up from acute inpatient discharge.
