99211

Office or other outpatient visit for the evaluation and management of an established patient (Level 1)

CPT 99211 is a level 1 evaluation and management (E/M) code specifically designed for the office or other outpatient visit of an established patient. It is unique among E/M codes because it is the only code that does not require the presence of a physician or other qualified healthcare professional (QHP) for the performance of the service, although it is typically performed under the physician's direct supervision. Often referred to as a "nurse visit," this code is reported when clinical staff, such as a registered nurse (RN), licensed practical nurse (LPN), or medical assistant (MA), provide services that involve an evaluation and management component that is medically necessary. To qualify for 99211, the encounter must go beyond a simple technical task (like a blood draw) and must include some level of clinical assessment and decision-making or patient management. The service must be performed in the office or outpatient setting, and the patient must meet the CPT definition of an established patient (one who has received professional services from the physician/QHP or another physician/QHP of the exact same specialty and subspecialty who belongs to the same group practice within the past three years). Documentation must clearly support the medical necessity of the visit, the specific evaluation performed, the management provided, and the identity of the staff member providing the service. For Medicare and many other payers, this code is subject to "incident-to" billing requirements, meaning the physician must be present in the office suite and immediately available to provide assistance if needed.

Clinical Indications

  • Blood pressure monitoring for patients with a known diagnosis of hypertension
  • Evaluation and dressing change for a wound requiring clinical assessment
  • Suture or staple removal not within a global surgical period
  • Patient education regarding a new medication, medical device, or self-injection technique
  • Monitoring of patients on long-term anticoagulation therapy (e.g., Warfarin/INR monitoring)
  • Triage of acute symptoms to determine the necessity of a higher-level physician encounter
  • Follow-up for glucose monitoring and insulin adjustment education in diabetic patients
  • Inhaler technique review for asthma or COPD patients
  • Assessment of therapeutic response to a recently changed medication

Procedure Steps

  1. Verify the patient's identity and status as an established patient of the practice.
  2. Identify the reason for the visit and obtain a focused clinical history.
  3. Perform relevant physiological measurements (e.g., blood pressure, weight, heart rate) or localized physical assessment (e.g., wound site).
  4. Assess the patient's clinical status relative to the reason for the encounter.
  5. Provide management or instruction (e.g., education on medication side effects, wound care instructions, or confirming the next titration step).
  6. Communicate findings or results to the supervising physician as necessary.
  7. Document the encounter in the medical record, including the clinical staff's signature and the supervising physician's name.
  8. Ensure that the supervising physician is present in the office suite at the time of service for 'incident-to' compliance.

Coding Guidelines

  • Code 99211 is restricted to established patients only; there is no new patient equivalent for this service level.
  • The service does not require a specific amount of time, nor does it require a physician to see the patient personally.
  • Do not report 99211 if the only service provided is a technical procedure with its own CPT code, such as a venipuncture (36415) or an immunization administration (90460-90474).
  • 99211 should not be reported for administrative tasks such as prescription refills or scheduling appointments.
  • Under Medicare 'incident-to' rules, the physician must have established the plan of care that the clinical staff is following during the 99211 encounter.
  • If a procedure with a global period was performed, 99211 cannot be used for routine post-operative follow-up related to that procedure.
  • The service must be medically necessary; routine screenings without clinical management do not qualify.
