Medical-necessity criteria UnitedHealthcare generally applies

[NEEDS CLINICAL SPOT-CHECK] Governing document: UnitedHealthcare Commercial and Individual Exchange Medical Policy "Epidural Steroid Injections for Spinal Pain", Policy Number 2026T0616N, effective 2026-06-01. Applicable codes listed in the policy: 62320, 62321, 62322, 62323, 64479, 64480, 64483, 64484. COVERAGE RATIONALE (verbatim): "Epidural Steroid Injections (ESIs) are proven and medically necessary when all the following criteria are met: The injection is intended for the management of Radicular Back Pain, as evidenced by history and physical examination; and The Radicular Back Pain is unresponsive to the following conservative treatment for >= 4 weeks: Pharmacotherapy such as nonsteroidal anti-inflammatory drugs or acetaminophen; or Activity modification (including but not limited to heavy lifting, bending, and spinal torsion activities); or Physical therapy or home exercise; and There is evidence of structural and/or functional nerve root involvement by imaging or electrodiagnostic studies; and The injection is performed under fluoroscopic or computed tomography guidance". CONTRAINDICATIONS (verbatim): "Conditions that would contraindicate ESIs include but are not limited to: Spinal neoplasm; Rapidly progressing neurological deficit; Epidural abscess". UNPROVEN / NOT MEDICALLY NECESSARY (verbatim): "The use of ultrasound guidance for ESIs" and "ESIs for all other indications of the spine not included above". ESI LIMITATIONS (verbatim): "A maximum of four ESI sessions (per region, regardless of level, location, or side) per year. A session is defined as one date of service in which ESIs are performed. A region is defined by either the region of the cervical, thoracic, or lumbosacral. A year is defined as the 12-month period starting from the date of service of the first approved injection." Subsequent ESIs (verbatim): "Subsequent ESIs may be provided only if: Radicular Back Pain has returned and/or deterioration in function has occurred; and One of the following: The previous injection resulted in <= 50% pain relief or functional improvement for less than 3 months, as measured by validated measurement tools, and there has been a reassessment of the individual and the injection site and technique; or The previous injection resulted in >= 50% pain relief or functional improvement for 3 or more months, as measured by validated measurement tools". WHEN PRIOR AUTHORIZATION IS ACTUALLY REQUIRED (from "Prior Authorization Requirements for UnitedHealthcare", effective 2026-01-01): under "Pain management and injection", prior authorization is required for 62320, 62322, 62324, 62325, 62326, 62327, 62350, 62351, 62360, 62361, 64451, 64484, 64520, 64620, 64640, E0782, E0783, E0785, E0786 and G0260 — note 64484 IS on this list but 62321, 62323, 64479, 64480 and 64483 are NOT. Separately, under the "Site of service (SOS) — office-based program" (verbatim): "Prior authorization required if performed in an outpatient hospital setting or ASC. Prior authorization not required if performed in an office." The SOS lists name Musculoskeletal codes 27096, 64479, 64490, 64493 and Neurologic codes 62270, 62321, 64633, 64635, and state that SOS prior authorization "is not required for care providers in Alaska, Guam, Massachusetts, Puerto Rico, Rhode Island, Texas, Utah, the Virgin Islands and Wisconsin" — New Jersey is NOT exempt, so the site-of-service rule applies to this practice. CONSERVATIVE DEFAULT: CPT 62323, 64480 and 64483 appear on neither the flat PA list nor the SOS lists in the fetched document. Praxigen did not confirm their PA status; verify each code in the UnitedHealthcare Provider Portal PA tool for the specific member and place of service rather than inferring from this row.
