Frequency reminders for epidural steroid injections
May 12, 2025

This article is for providers who use Authorization Manager for musculoskeletal services

Thank you for using Authorization Manager to submit your requests for musculoskeletal services. As a reminder for epidural steroid injection (ESI) requests, please select the appropriate frequency based on the following criteria.

Transforaminal ESIs: In a single session, you should perform either a 1-level, bilateral transforaminal ESI or a 2-level, unilateral transforaminal ESI.

Interlaminar and caudal ESIs: In a single session, you should perform a single, 1-level caudal or interlaminar ESI.

Additional reminders for all ESIs:

  • We cover a maximum of four sessions per six-month period and six sessions per 12-month period regardless of the number of injections performed during each session.
  • We cover a maximum of four sessions per spine region per year (cervical and thoracic is one region, and lumbar and sacral is one region).
  • Transforaminal injections should not be given with caudal or interlaminar injections in the same session.
