Summary & Overview
CPT 94761: Multiple Oxygen Saturation Measurements (Ear or Finger)
CPT code 94761 represents multiple measurements of a patient’s oxygen saturation using a sensor on the ear or finger. This brief point-of-care procedure is commonly used to monitor peripheral oxygenation in acute and outpatient settings, informing immediate clinical decisions about oxygen therapy, respiratory status, and need for escalation of care. Nationally, codes for pulse oximetry like 94761 matter because they capture a frequent, low-complexity clinical activity that influences quality metrics, utilization tracking, and payment for respiratory monitoring services.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of what the code represents, the typical sites of service and clinical context, and where to find additional operational details. The publication summarizes benchmarks and policy considerations relevant to billing and documentation for pulse oximetry services, clarifies service definition for coding teams, and highlights common areas where payers may require explicit documentation. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 94761 documents repeated measurements of a patient’s oxygen saturation using a sensor placed on the ear or finger. The service involves taking multiple spot-check readings to assess peripheral oxygenation over a brief period.
-
Service type: Pulse oximetry measurements
-
Typical site of service: Ambulatory clinic, hospital bedside, emergency department, or other point-of-care settings where rapid oxygenation assessment is required
Data not available in the input for payers, associated taxonomies, ICD-10 diagnoses, and related codes.
Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with chronic obstructive pulmonary disease (COPD) presents to an outpatient pulmonary clinic for evaluation of progressive dyspnea and intermittent hypoxia. The clinician applies a pulse oximeter sensor to the patient’s finger and obtains multiple oxygen saturation measurements during rest, after a standardized six-minute walk test, and with supplemental oxygen titrated as needed. The provider documents each SpO2 measurement, the device used, time stamps, activity level (rest, ambulation), and any interventions (oxygen flow adjustments). Typical workflow: triage nurse places sensor and records initial value; provider repeats measurements during examination and with exertion; findings guide oxygen prescription, further testing (arterial blood gas, overnight oximetry), or escalation of care.
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 | Use when a separate E/M visit is performed in addition to multiple SpO2 measurements and documented as distinct. |
26 | Professional component |
