Anthem is the BCBS-licensed plan operating in 14 states (California, Colorado, Connecticut, Georgia, Indiana, Kentucky, Maine, Missouri, Nevada, New Hampshire, New York, Ohio, Virginia, and Wisconsin) and is the largest single subsidiary of Elevance Health, formerly known as Anthem, Inc. Elevance also owns Carelon, an in-house clinical services arm that performs many of Anthem's prior-authorization reviews for advanced imaging, musculoskeletal procedures, cardiac procedures, and specialty drugs, plus CarelonRx for pharmacy benefits and Wellpoint for Medicaid managed care. Anthem participates in the BlueCard cross-state network that lets BCBS members access in-network care from any BCBS provider in any state, which means appeals on care received outside your home Anthem state involve a routing layer between the home plan (Anthem) and the host plan (the local BCBS licensee). Anthem also offers Medicare Advantage and Medicare Supplement products under both the Anthem and Wellpoint brands depending on state. In New York, the historical Empire BlueCross BlueShield brand was rebranded under the Anthem umbrella; older denial letters may still reference Empire while newer denials use Anthem branding. Anthem's commercial product line is split between fully insured products regulated by the state department of insurance and Administrative Services Only / self-funded ERISA products administered for employer groups - the appeal procedure differs between the two and the Summary Plan Description controls for ASO members.

Common Anthem denial patterns
These are the denial patterns we see most often from Anthem members based on publicly-reported insurer policies and regulator findings. The right appeal approach depends on which pattern matches your denial.
- Medical-necessity denials citing Anthem's UM (Utilization Management) Guidelines, especially for spinal procedures, cardiac procedures, and advanced imaging
- Site-of-service denials redirecting outpatient surgeries from hospital outpatient to ambulatory surgery centers
- Prior-authorization denials for high-cost specialty drugs administered through CarelonRx
- BlueCard cross-state coverage disputes
- Behavioral health denials - subject to MHPAEA parity scrutiny
- Emergency-room claims retroactively denied as non-emergent (especially historic Anthem policy in GA, MO, KY, IN, OH, NH)
- Carelon / AIM advanced-imaging denials applying tighter clinical criteria than the underlying Anthem policy
How Anthem's appeal process works
Anthem gives most members 180 days from the denial notice to file a written appeal. The first level is reviewed by Anthem; depending on your plan you may have a second internal level or move directly to external review. Anthem operates the BlueCard program for members who receive care across BCBS networks - the home plan handles claims processing but the host plan executes the service, and appeals can become routing-complex. Quote Anthem's specific UM Guideline number when contesting a medical-necessity denial.
Step 1: Identify the reviewer. Anthem denials commonly cite an Anthem UM Guideline, an AIM Specialty Health / Carelon criterion (advanced imaging, cardiology, oncology), or a CarelonRx pharmacy criterion. The Guideline number is on the denial. Step 2: Confirm the appeal address from your specific EOB - Anthem routes by state and product. Step 3: File a written first-level appeal within 180 days, including the denial notice, claim or authorization number, the specific UM Guideline contested, a physician letter of medical necessity, and supporting clinical evidence. Step 4: For BlueCard claims, identify both the home plan (Anthem) and the host BCBS plan in the appeal letter so the routing is unambiguous. Step 5: Mark the appeal expedited and have your physician confirm urgency in writing if delay would jeopardize your health - decision must come within 72 hours. Step 6: If the first-level appeal is denied, file a second-level internal appeal if your plan offers one (commonly available for commercial group plans). Step 7: After internal exhaustion, request external review through your state's process - in California through the DMHC Independent Medical Review, in New York through the Department of Financial Services external appeal, etc.
What makes Anthem appeals succeed
Anthem appeals succeed most often when they: (1) quote the specific Anthem UM Guideline by number and demonstrate either that the case meets the Guideline criteria or that the Guideline conflicts with current standard of care for the diagnosis, with peer-reviewed clinical literature attached; (2) address Carelon / AIM by name when the underlying review came from there, since the appeal review needs to engage with that vendor's criteria rather than Anthem's general policy; (3) invoke MHPAEA parity for behavioral-health and substance-use denials and request the Non-Quantitative Treatment Limitation comparative-analysis documentation that the 2024 final rule entitles members to; (4) cite the home-state external-review program (DMHC IMR for California Anthem, NY Department of Financial Services external appeal for Empire / Anthem in New York, Ohio Department of Insurance external review, etc.) so Anthem knows the patient is prepared to escalate; (5) for BlueCard claims, route through the home Anthem plan but reference the host plan's role and any host-plan medical policy that the reviewer needs to consider; (6) for site-of-service redirection denials, attach a clinical justification for why the higher-acuity site is medically necessary (e.g. comorbidities that require hospital outpatient anesthesia and recovery rather than ambulatory surgery center); and (7) preserve a complete written record of timeliness by sending the appeal via certified mail with return receipt.
Recent regulatory and public-record context
Elevance Health's California Anthem subsidiary has historically been one of the most-cited insurers by the California Department of Managed Health Care for grievance and access-to-care violations. The DMHC has issued multiple enforcement actions and settlements involving Anthem, including parity-related actions on mental-health timeliness. Nationally, Elevance was named in 2024 reporting on Medicare Advantage prior-authorization scrutiny by the Senate Permanent Subcommittee on Investigations and the HHS OIG. Anthem's 2017 emergency-room policy in Georgia, Missouri, Kentucky, Indiana, Ohio, and New Hampshire - which retroactively denied ER claims that Anthem deemed non-emergent - drew consumer-protection lawsuits and was substantially scaled back after public scrutiny.
