Summary & Overview

HCPCS G9456: Documentation of Reason for Not Performing HCC Screening

HCPCS Level II code G9456 denotes documentation of clinical or patient reasons for not ordering or performing hepatocellular carcinoma (HCC) screening. The code is used when clinicians record medical justifications (for example, limited life expectancy under five years or hepatic decompensation precluding transplant candidacy) or patient-centered reasons (for example, the patient declined screening or faced barriers such as cost or access). Nationally, consistent use of G9456 supports accurate quality measurement and claims reporting related to HCC surveillance practices.

Key payers in scope include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will learn how G9456 is applied in clinical documentation, the service and settings where it is typically used, and what elements are relevant for billing and quality reporting. The publication summarizes benchmarks and policy-relevant considerations, clarifies clinical context for when HCC screening is deferred, and outlines common payer and coding topics practitioners and billing staff should expect to encounter.

Billing Code Overview

HCPCS Level II code G9456 documents the medical or patient reason(s) for not ordering or performing screening for hepatocellular carcinoma (HCC). The code captures instances where clinicians record a medical reason (for example, comorbid conditions with expected survival < 5 years or hepatic decompensation making the patient not a transplant candidate) or a patient reason (for example, patient declined testing or barriers such as cost or time to access testing equipment).

Service type: Clinical documentation of deferred or not-performed screening.

Typical site of service: Outpatient clinic, specialty hepatology or gastroenterology practice, or other ambulatory care settings where HCC screening decisions are made.

Data not available in the input.

Clinical Context

A 72-year-old man with Child-Pugh C cirrhosis from chronic hepatitis C and multiple comorbidities (ischemic cardiomyopathy with ejection fraction 25%, advanced chronic obstructive pulmonary disease on home oxygen, and metastatic prostate cancer) presents to his hepatology clinic for routine follow-up. The clinician documents that hepatocellular carcinoma (HCC) surveillance with abdominal ultrasound ± alpha-fetoprotein (AFP) is not ordered because the patient has limited life expectancy (< 5 years) and is not a candidate for liver transplantation due to severe cardiac disease and active metastatic malignancy. The clinician reviews risks and benefits with the patient, who declines surveillance given the preference to focus on symptom management.

Typical clinical workflow:

Initial assessment: Review of medical history, recent imaging, and transplant candidacy.
Shared decision-making: Discussion with the patient about HCC screening options, prognosis, and potential interventions.
Documentation: Clinician documents specific medical reasons (expected survival < 5 years; hepatic decompensation; not transplant candidate) and patient reasons (patient declined) for not ordering HCC screening.
Billing: Use of the HCPCS Level II code G9456 to indicate documented medical or patient reason(s) for not ordering or performing HCC screening.
Follow-up planning: Establishes plan for symptom-directed care and palliative involvement as appropriate.

Taxonomy Code	Specialty	Notes
`207P00000X`	Gastroenterology	Hepatology and GI physicians commonly document HCC surveillance decisions.
`208000000X`	Internal Medicine	General internists manage cirrhosis care and surveillance decisions.
`208D00000X`	Family Medicine	Family physicians may document screening decisions in primary care settings.
`363L00000X`	Palliative Medicine	Specialists documenting goals of care and reasons to defer surveillance.
`207L00000X`	Transplant Hepatology	Providers evaluating transplant candidacy and documenting reasons to defer HCC screening.

Related Diagnoses

ICD-10 Code	Description	Clinical Relevance
`K74.60`	Unspecified cirrhosis of liver	Cirrhosis is the primary condition requiring HCC surveillance; presence of advanced cirrhosis may influence decision to defer screening.
`K72.90`	Hepatic failure, unspecified without coma	Hepatic decompensation indicating poor prognosis and unsuitability for transplant, supporting use of `G9456`.
`C79.51`	Secondary malignant neoplasm of liver and intrahepatic bile duct	Metastatic disease to the liver affects prognosis and alters surveillance strategy.
`I50.22`	Chronic systolic (congestive) heart failure	Severe cardiac comorbidity that may limit life expectancy and transplant candidacy.
`C61`	Malignant neoplasm of prostate	Active metastatic malignancy or competing terminal illness that reduces expected survival and changes screening decisions.

Related CPT Codes

CPT Code	Description	Relationship to This Procedure
`76700`	Ultrasound, abdomen, real time with image documentation; complete	Commonly ordered for HCC surveillance; documentation `G9456` applies when this surveillance is not ordered or not performed.
`76705`	Ultrasound, limited, follow-up or targeted	Used for focused liver imaging when limited surveillance is performed; contrasts with documentation for not screening.
`78975`	Ultrasound, abdominal, real time with image documentation, limited—single area	Relevant when only a limited exam is done; `G9456` documents reasons if surveillance is declined.
`81210`	Alpha-fetoprotein (AFP) testing (molecular pathology) — (Note: AFP is often billed as a lab CPT by local lab codes)	AFP measurement is an adjunct to HCC surveillance; documentation supports why laboratory surveillance was not ordered.
`99497`	Advance care planning including completion of advance directive, first 30 minutes	Often performed when deferring surveillance for patients with limited life expectancy; documents goals of care that relate to `G9456`.

`22`	Increased procedural services	Use if work required to document complex medical justification for not ordering screening is substantially greater than typical documentation time.
