Implementation of Billing for Patient Portal Messages as E-visits in a Large Integrated Health System

Patient-provider communication through the patient portal has markedly increased in recent years. Some health care facilities implemented programs to enable providers to bill for responding to patient-initiated messages that require substantive medical decision making through an e-visit.

To evaluate the effect of billing eligible patient-initiated portal messages as e-visits using a mixed-methods approach.

Retrospective observational pre-post comparison and prospective survey.

Large integrated health system with sites in 4 U.S. states.

Patients initiating portal message threads and health system providers completing an online survey.

E-visit billing was implemented 18 August 2023.

The volume of patient-initiated medical advice message threads pre- versus postimplementation of e-visit billing was compared. Health system provider perceptions of e-visit billing were assessed using an online survey.

In the 6 months after e-visit billing implementation (18 August 2023 through 18 February 2024), the volume of patient-initiated medical advice message threads decreased by 8.8% (from 1 813 818 to 1 653 708) compared with the same dates the year prior (P = 0.002). A total of 5183 (0.3%) medical advice messages were billed. There was no difference in 7-day use of emergency services (emergency department visits or hospitalizations) in patients who proceeded with sending a message versus those that did not send a message after viewing the billing disclaimer on the patient portal. Providers reported overall acceptance of e-visit billing but expressed concerns about increased workload with the current process.

Cannot assess changes in other forms of contact, including telephone calls.

These findings suggest that implementation of e-visit billing was associated with a modest decrease in patient-initiated portal message volume and was overall acceptable to providers in a large integrated health system.

None.
