Summary & Overview
HCPCS G8773: Urine Protein Test Not Performed
HCPCS Level II code G8773 documents that a urine protein test was not performed and no reason was recorded. Nationally, accurate documentation of omitted diagnostic tests affects quality measurement, care continuity, and denials management when payers review completeness of care. This code signals a gap in either clinical documentation or test administration and is relevant for ambulatory care and laboratory service workflows.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the code’s clinical context, where it is typically used, and why it matters for quality reporting and claims processing. The publication outlines common benchmarks and policy considerations, including how omission codes interact with payer documentation requirements and audit processes. It also provides practical information on typical sites of service and the service type associated with the code.
This summary serves clinicians, billing professionals, and policy analysts seeking a national perspective on the use and implications of G8773 for documentation quality, claims integrity, and diagnostic testing workflows.

Clinical & Coding Specifications
Clinical Context
A typical outpatient primary care visit for a patient with diabetes mellitus includes routine urine screening for proteinuria to evaluate for diabetic kidney disease. The clinician orders a urine protein test during the visit, but a specimen is not obtained or the laboratory does not perform the test. The reason for nonperformance is not recorded in the chart. The medical record documents the order and the intent to screen, but lacks documentation of specimen collection, inability to obtain a specimen, patient refusal, or laboratory cancellation. The workflow typically involves: ordering the urine protein test at the point-of-care or via lab requisition, providing specimen cups and collection instructions to the patient, receiving the specimen in the clinic or sending the patient to a draw station, and performing either a urine dipstick, urine protein-to-creatinine ratio, or laboratory quantitative urine protein assay. In this scenario the process stops after the order and no test result is produced, with no documented explanation for the absence of testing.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
24 | Unrelated evaluation and management service by the same physician during a postoperative period | Use when a medically necessary E/M occurs unrelated to a recent procedure during postoperative period; rarely applicable to test nonperformance events but relevant to E/M claims on the same day. |
