CPT® Code 99211

CPT® Code 99211 is used to report an evaluation and management (E/M) service for an established patient that does not require the presence of a physician or other qualified healthcare professional (QHP). This code represents the lowest level of E/M services and is often used for brief, minimal complexity encounters.

Overview

This code is commonly referred to as the "nurse visit" code. It covers encounters where a clinical staff member (such as a nurse or medical assistant) interacts with the patient for a medically necessary reason, but no direct physician or QHP involvement occurs during the visit.

Despite its simplicity, 99211 requires documentation to support medical necessity and appropriate clinical decision-making, even if minimal.

Typical Patient Description

A patient returns to the clinic for a blood pressure check as part of ongoing hypertension monitoring. A medical assistant records the reading, documents it in the chart, and updates the provider if needed. No physician is directly involved during the visit.

Other examples include:

  • Injection follow-up
  • Wound dressing change
  • B12 shot without evaluation
  • Review of lab results with instructions relayed by staff

Care Components

  • Established patient only: This code applies only to patients previously seen in the practice.
  • Minimal complexity: No medical decision-making beyond basic instruction, documentation, or clinical data collection.
  • No physician required: Service can be delivered solely by clinical staff under general supervision.
  • Brief time requirement: Typically 5 minutes or less.

Billing Considerations

  • Requires documentation: Even minimal services must include the reason for the visit, intervention performed, and medical necessity.
  • Cannot be billed for administrative tasks: Services like medication refills, appointment scheduling, or weight checks without medical necessity are not billable under 99211.
  • Not time-based: This is an event-based E/M code, not billed by time.
