Summary & Overview

HCPCS G8775: Documentation of Reason for Not Performing Serum Creatinine Test

HCPCS Level II code G8775 denotes documentation of clinical reasons for not performing a serum creatinine test, such as when patients have palliative care goals or when standard hypertension treatment targets are not clinically appropriate. As a documentation-focused HCPCS Level II code, G8775 captures clinician-recorded justification that a routine laboratory test was intentionally withheld for patient-centered or clinical-safety reasons. Nationally, clear documentation supporting test omission is relevant for quality reporting, continuity of care, and payer review processes.

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 settings where it is used, and the kinds of documentation that support applying the code. The publication also outlines common benchmarking topics and policy considerations related to documentation-based HCPCS Level II codes, including how they intersect with quality measures and medical necessity reviews. Where available, it summarizes payer approaches and administrative expectations; when payer-specific data are not provided, the report notes that detailed payer policy information is not available in the input.

This summary is intended for clinicians, revenue cycle staff, and policy analysts seeking a concise national-level briefing on HCPCS Level II code G8775, its purpose, and its relevance to documentation and quality processes.

Billing Code Overview

HCPCS Level II code G8775 documents the medical reason(s) for not performing a serum creatinine test, for example when a patient has palliative goals or when standard hypertension treatment targets are not clinically appropriate. This code captures clinical justification recorded in the medical record that a serum creatinine test was intentionally not ordered or performed due to patient-centered or clinical-care considerations.

Service type: Clinical documentation of rationale for omission of a laboratory test

Typical site of service: Outpatient clinic, primary care office, specialty clinic, or any ambulatory care setting where hypertension management or palliative care decisions are made

Data not available in the input.

Clinical & Coding Specifications

Clinical Context

A typical patient scenario involves an adult patient with hypertension who is under hospice or palliative care, or whose overall goals of care prioritize symptom management rather than strict blood pressure targets. During an outpatient primary care or nephrology visit, the clinician documents that a serum creatinine test will not be performed because the result will not change management, the patient has limited life expectancy, or aggressive hypertension treatment is not clinically appropriate. Documentation includes the medical rationale (for example, palliative goals, advanced dementia, frailty, or terminal illness), the discussion with the patient or surrogate, and the plan for blood pressure management aligned with goals of care.

Clinical workflow:

The patient presents for a routine hypertension follow-up or medication review.
The clinician reviews the patient’s history, current status, and goals of care (including hospice/palliative designation if present).
The clinician determines that obtaining a serum creatinine would not alter treatment decisions due to palliative goals, limited expected benefit, or contraindications to standard hypertension targets.
The clinician documents the medical reason(s) for not performing the serum creatinine, including relevant clinical context, discussion with patient or surrogate, and the alternative plan for monitoring or medication adjustments.
The clinician flags the encounter in the medical record and bills the appropriate HCPCS Level II code G8775 to indicate documentation of medical reason(s) for not performing serum creatinine testing.

Modifier	Description	When to Use
`25`	Significant, separately identifiable evaluation and management (E/M) service by the same physician on the same day of the procedure or other service	Use when an E/M visit addresses issues beyond documenting reasons for not performing serum creatinine, such as new complaints or complex decision-making.
`57`	Decision for surgery	Rarely applicable; use when documentation of non-testing is tied to a decision that leads to surgery on the same day.
`59`	Distinct procedural service	Use when another distinct procedure is performed the same day and needs separation from services related to `G8775` documentation.
`76`	Repeat procedure or service by same physician	Use if the documentation of medical reasons is repeated on the same day for confirmation or additional justification.
`77`	Repeat procedure by another physician	Use if a different clinician documents the medical reason for not performing the test on the same day.
`91`	Repeat clinical diagnostic laboratory test	Not directly applied to `G8775`; include for completeness when a repeat lab is actually performed instead of documented omission.
`GT`	Via interactive audio and video telecommunications (Telehealth)	Use when the documentation and counseling occur during a live telehealth visit.
`95`	Synchronous telemedicine service rendered via real-time interactive audio and video	Use when service is provided through telemedicine platforms and documentation meets requirements.
`AE`	Physician of the Air Force (example taxonomy modifier for military claims)	Use on claims when billing payors require provider status modifiers specific to military or federal provider relationships.
`GA`	Waiver of liability statement issued, expected to be paid by Medicare	Use when a voluntary ABN (Advance Beneficiary Notice) is issued and documented related to not performing testing.

Taxonomy Code	Specialty	Notes
`207Q00000X`	Family Medicine	Primary care clinicians commonly document rationale for not ordering labs in patients with palliative goals.
`207R00000X`	Internal Medicine	Hospitalists and outpatient internists frequently perform medication management and document lab omissions.
`2080P0005X`	Hospice and Palliative Medicine	Specialists in palliative care document goals-concordant decisions to withhold non-beneficial testing.
`208000000X`	Nephrology	Nephrologists may document reasons not to pursue creatinine testing when it will not change renal-focused management.
`207K00000X`	Geriatric Medicine	Geriatricians assess frailty and life expectancy and document avoidance of burdensome testing.

Related Diagnoses

`F03.90`	Unspecified dementia without behavioral disturbance	Cognitive impairment that may lead to goals of care focused on comfort rather than diagnostic testing.
`C80.1`	Malignant neoplasm, unspecified, with metastasis	Advanced metastatic disease where life expectancy and treatment goals may render creatinine testing non-actionable.
