Summary & Overview
CPT 82948: Reagent Strip Blood Glucose Test
CPT code 82948 represents a clinician-performed reagent strip test to measure blood glucose. Point-of-care glucose testing is a common, rapid diagnostic service used across outpatient offices, clinics, emergency departments, and inpatient settings to inform immediate clinical decisions for patients with suspected or known dysglycemia. Nationally, this code matters because it captures a frequent, low-complexity diagnostic interaction that affects resource use, clinical workflows, and quality measurement for diabetes care.
Key payers covered in this overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise presentation of what CPT code 82948 covers, typical sites of service and clinical context, and pointers to the types of benchmarks and policy considerations commonly associated with point-of-care glucose testing. The publication outlines expected service characteristics, common modifiers (listed separately), and areas where policy updates—such as coverage rules, billing guidance, and documentation expectations—can influence use and reimbursement. The summary is intended for clinicians, billing professionals, and policy analysts seeking a national-level understanding of the code’s clinical role and billing context.

Billing Code Overview
CPT code 82948 describes a clinician-performed reagent strip test for measurement of glucose in blood. The procedure involves using a reagent strip method to determine blood glucose concentration at the point of care.
Service type: Point-of-care glucose testing
Typical site of service: Office, clinic, emergency department, inpatient bedside, or other point-of-care locations

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with known diabetes mellitus or symptoms suggestive of hyperglycemia or hypoglycemia who presents to an outpatient clinic, emergency department, or inpatient nursing unit for immediate point-of-care assessment. The clinician obtains a capillary fingerstick sample and performs a reagent strip glucose test (82948) to determine blood glucose concentration for treatment decisions. Workflow: triage/nursing documents symptoms and indication, obtains consent as required, performs fingerstick using a validated glucometer and reagent strip, records result in the medical record, and notifies the ordering clinician for medication adjustment (insulin, dextrose) or disposition (discharge, observation, admission). Typical sites of service include primary care offices, urgent care clinics, emergency departments, hospital wards, and outpatient diabetes clinics.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
25 | Significant, separately identifiable evaluation and management service by the same physician on the same day of the procedure or other service | Use when an E/M visit is performed on the same day as 82948 and is distinct from the glucose test (e.g., new problem evaluation). |
26 | Professional component | Use if reporting only the professional component when separate ownership of the testing equipment applies (rare for POC strip tests). |
59 | Distinct procedural service | Use to indicate the glucose test is separate and distinct from another service provided the same day. |
76 | Repeat procedure by same physician or other qualified health care professional | Use when the reagent strip test is repeated during the same encounter for clinical reasons. |
77 | Repeat procedure by another physician or other qualified health care professional | Use when a second clinician repeats the test. |
91 | Repeat clinical diagnostic laboratory test | Use when multiple glucose determinations are performed on the same day to monitor trend and billing requires repeat-test modifier. |
52 | Reduced services | Use if the glucose test is partially reduced or not fully performed. |
53 | Discontinued procedure | Use if the reagent strip test is started but discontinued for documented medical reasons. |
59 | Distinct procedural service | Use when necessary to indicate a separate POC test service on the same day (included here due to relevance). |
95 | Synchronous telemedicine service rendered via real-time interactive audio and video | Use if the clinician supervises or interprets the POC glucose testing in a telemedicine encounter where modifier 95 is required by payer. |
