Summary & Overview

HCPCS G9722: History of Renal Failure or Baseline Creatinine ≥ 4.0 mg/dL

HCPCS Level II code G9722 indicates a documented history of renal failure or a baseline serum creatinine of 4.0 mg/dL or higher; renal transplant recipients are excluded unless their creatinine meets or exceeds that threshold post-transplant. Nationally, this code flags severe baseline kidney dysfunction that can affect perioperative risk assessment, care planning, and quality measurement. It is relevant across hospital and ambulatory surgical settings where preoperative evaluations are performed.

Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical context and intended use of G9722, plus what to expect in benchmarking and policy discussions: coding purpose, typical sites of service, and how the code is applied in preoperative documentation. The publication outlines national considerations for recognizing severe renal impairment in surgical candidates, summarizes common modifiers associated with the service line, and identifies gaps where input data were not provided.

This overview provides clinicians, coders, and policy stakeholders with the context needed to interpret use of HCPCS Level II code G9722 in clinical documentation, administrative reporting, and quality review processes.

Billing Code Overview

HCPCS Level II code G9722 documents a history of renal failure or a baseline serum creatinine ≥ 4.0 mg/dL. The definition specifies that renal transplant recipients are not considered to have preoperative renal failure unless their serum creatinine has been or is ≥ 4.0 mg/dL since transplantation. This code is used to capture a patient-level clinical condition that may affect perioperative management and risk stratification.

Service Type: Preoperative risk/medical history documentation related to severe renal impairment

Typical Site of Service: Inpatient and outpatient preoperative evaluation settings, surgical clinics, and hospital admission documentation where preoperative assessment occurs

Data not available in the input for associated taxonomies, ICD-10 diagnoses, and related codes.

Clinical & Coding Specifications

Clinical Context

A typical patient is an adult with a documented history of end-stage renal disease or a baseline serum creatinine ≥ 4.0 mg/dL presenting for a surgical procedure that requires preoperative risk stratification and coding for high renal impairment. Example: a 62-year-old male with chronic kidney disease stage 5 (baseline creatinine 4.6 mg/dL) scheduled for an urgent open hernia repair under general anesthesia. Preoperative evaluation documents renal failure history in the medical record, includes current serum creatinine, dialysis schedule, and perioperative medication adjustments. The surgical team and anesthesiology document the renal status in the operative and anesthesia records. Coding staff assign G9722 to identify documented preoperative renal failure when present; renal transplant recipients are coded with G9722 only if their postoperative or post-transplant serum creatinine is ≥ 4.0 mg/dL. Typical workflow: preoperative clinic documents creatinine and dialysis history → anesthesia and surgery notes reiterate renal impairment → coder abstracts G9722 and links it to the surgical encounter for risk adjustment and quality reporting purposes.

Taxonomy Code	Specialty	Notes
`207RC0000X`	General Surgery	Commonly performs operations where preoperative renal failure must be documented for risk stratification.
`208D00000X`	Anesthesiology	Responsible for perioperative assessment and anesthesia plan in patients with severe renal impairment.
`208800000X`	Vascular Surgery	Performs procedures in patients with renal failure (e.g., dialysis access, complex vascular reconstructions).
`207RG0100X`	Transplant Surgery	Evaluates renal transplant recipients and documents transplant function relative to `G9722` criteria.

Related Diagnoses

ICD-10 Code	Description	Clinical Relevance
`N18.6`	End stage renal disease	Primary diagnosis indicating dialysis-dependent renal failure; clearly relevant to `G9722`.
`N18.5`	Chronic kidney disease, stage 5	Severe CKD often with creatinine ≥ 4.0 mg/dL; meets `G9722` clinical threshold.
`Z94.0`	Kidney transplant status	Identifies transplant recipients; per `G9722`, transplant status alone does not qualify unless creatinine ≥ 4.0 mg/dL.
`R94.31`	Abnormal serum creatinine level	Documents elevated creatinine measurements; supports documentation for `G9722` when value meets threshold.
`Z99.2`	Dependence on renal dialysis	Indicates dialysis dependence and chronic renal failure relevant to preoperative risk coding.
