Amerigroup On Call is a telephonic, 24-hour triage service your Amerigroup patients can call to speak with a registered nurse who can help them:

  • Find doctors when your office is closed, whether after hours or weekends.
  • Schedule appointments with you or other network doctors.
  • Get to urgent care centers or walk-in clinics.
  • Speak directly with a doctor or a member of the doctor’s staff to talk about their health care needs.

We encourage you to tell your Amerigroup patients about this service and share with them the advantages of avoiding the emergency room when a trip there isn’t necessary or the best alternative. TTY services are available for the hearing impaired, and language translation services are available.

Our care managers are licensed nurses and social workers and are available from 8:30 a.m. to 5:30 p.m. Eastern time, Monday through Friday. Confidential voicemail is available 24 hours a day.

Please call 1-888-830-4300 to reach one of our care managers. Your patients can get information about DM program services by visiting or calling 1-888-830-4300.
