How to bill 99214 and G2211 together?


Editorial team Published on

To bill HCPCS add-on code G2211 with established patient office visit 99214, list 99214 as your primary evaluation and management (E/M) code and append G2211 on a separate line as an add-on service for visit complexity.

Core Billing Rules

  • Base Code Requirement: 99214 must be fully supported by your documentation (moderate medical decision-making or appropriate time).
  • Add-on Nature: G2211 cannot be billed by itself; it must always be paired with an eligible outpatient or office E/M code (99202–99215).
  • Longitudinal Relationship: You must have an ongoing, continuous relationship with the patient where you serve as the continuing focal point for all health care needs, or you are managing a single serious/complex condition.
  • Modifier 25: If you perform a separate procedure (like a minor procedure or injection) on the same day that requires modifier -25 on 99214, G2211 is allowed for payment as long as the underlying clinical criteria are met.

Documentation Requirements

To justify billing G2211 alongside 99214, your clinical note should clearly reflect the cognitive load and continuity of the relationship. Document:

  • Your role as the continuing focal point of care for the patient.
  • The longitudinal nature of the condition or conditions being managed.
  • The depth of the ongoing relationship addressing the patient's holistic health needs over time.
