Summary & Overview

HCPCS G9658: Transfer-of-Care Handoff Tool Not Used

HCPCS Level II code G9658 identifies situations where a required transfer-of-care protocol or handoff checklist that includes key handoff elements was not used. Nationally, this measure highlights gaps in clinical communication and care coordination that can increase risk during patient transitions between teams or settings. It is relevant to hospitals, emergency departments, ambulatory clinics, and other sites where structured handoffs are expected.

Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of what the code represents, payer coverage context, and the clinical setting implications. The publication provides benchmarks where available, summaries of applicable policy and coverage considerations, and clinical context around handoff protocols and patient safety implications. The material is intended for compliance officers, billing staff, clinical leaders, and policy analysts seeking a concise reference for G9658 and its role in documenting failures to use standardized handoff tools.

Billing Code Overview

HCPCS Level II code G9658 indicates that a transfer of care protocol or handoff tool/checklist that includes the required key handoff elements is not used. The service type is care coordination and patient safety communication focused on handoff processes during transitions of care. The typical site of service includes inpatient and outpatient settings where formal handoffs occur, such as hospitals, emergency departments, and ambulatory clinics where staff-to-staff or team-to-team transitions are performed.

Clinical & Coding Specifications

Clinical Context

A 68-year-old male is transferred from the emergency department to a hospital inpatient medical ward after presenting with community-acquired pneumonia and hypoxia. The ED team verbally communicates the patient’s condition, recent vitals, active problems, current antibiotics, oxygen requirement, and pending labs to the admitting hospitalist team, but no standardized transfer-of-care checklist or handoff tool is used. During the first 12 hours on the ward there is confusion about the antibiotic dosing schedule and whether the oxygen order was continued, prompting repeat assessment and clarification. The workflow typically involves the sending unit (ED or operating room), the receiving unit (inpatient ward or intensive care unit), bedside nursing, and the attending physician; documentation of the handoff occurs in the EHR but lacks a required structured checklist containing key elements (patient identifiers, current diagnosis, stability status, medications, allergies, pending results, contingency plans, and escalation criteria). This omission is what G9658 describes: a transfer of care protocol or handoff tool/checklist that includes the required key handoff elements is not used.

Coding Specifications

Modifier	Description	When to Use
`22`	Increased procedural services	Rarely applicable; may be appended when an associated service required substantially greater work due to handoff failures causing added interventions (use per payer rules).
`23`	Unusual anesthesia	Not typically applicable to this service; included for completeness when anesthesia is involved in concurrent procedures.
`52`	Reduced services	Use when a planned service accompanying the transfer was partially performed because of handoff issues.
`53`	Discontinued procedure	Use when a procedure is started but halted due to instability discovered during a deficient handoff.
`54`	Surgical care only	Use for the surgeon’s portion when handoff problems affect subsequent postoperative management by another provider.
`55`	Postoperative management only	Use when postoperative management is billed separately and impacted by inadequate handoff.
`56`	Preoperative management only	Use when preoperative evaluation was provided but transfer problems altered subsequent care.
`62`	Two surgeons	Use when two surgeons are involved due to complications arising after a deficient handoff necessitating additional operative involvement.
`AS`	Physician assistant, surgical assist	Use when an assistant provides services; relevant if handoff failures required extra personnel.
`CO`	Casts and other immobilization	Rarely relevant; included only if immobilization services were modified because of transfer omissions.

Taxonomy Code	Specialty	Notes
`207R00000X`	Internal Medicine	Hospitalists and general internists frequently receive patient handoffs and are affected by checklist omissions.
`207L00000X`	Emergency Medicine	Emergency physicians originate many transfers and are responsible for initial handoff content.
`208000000X`	General Surgery	Surgeons and surgical teams are involved in perioperative handoffs where checklists are standard practice.
`163W00000X`	Nurse Practitioner	NPs often perform admissions and handoff communication in inpatient settings.
`164W00000X`	Physician Assistant	PAs participate in transfers and are commonly involved in care continuity across units.

Related Diagnoses

ICD-10 Code	Description	Clinical Relevance
`J18.9`	Pneumonia, unspecified organism	Common reason for ED-to-inpatient transfer; requires clear medication and oxygen handoff.
`R09.02`	Hypoxemia	Represents oxygen requirement that must be communicated in handoff.
`I50.9`	Heart failure, unspecified	May complicate transfers and requires detailed fluid and medication plans at handoff.
`R65.20`	Severe sepsis without septic shock	High-acuity diagnosis where structured handoff elements (antibiotics, source control, labs) are critical.
`Z74.01`	Bed confinement status	Relevant for disposition planning and mobility orders communicated during handoff.

Related CPT Codes

CPT Code	Description	Relationship to This Procedure
`99221`	Initial hospital care, typically 30 minutes	Commonly billed by the admitting provider after a transfer; content and accuracy depend on an effective handoff.
`99285`	Emergency department visit for the high severity problem	Represents the sending ED encounter prior to transfer; documentation from this visit should be included in handoff.
`99231`	Subsequent hospital inpatient care, typically 15 minutes	Used for follow-up visits where clarification is needed when handoff tools were not used.
`99334`	Domiciliary, rest home, or custodial care services, established patient	Occasionally relevant when transfers occur from long-term care settings and handoffs are required.
`99496`	Transitional care management services, with high complexity	May be used in transitions of care out of the hospital; accurate handoffs and checklists affect eligibility and documentation.
