FAQs

FAQ 1: What happens if Anthem doesn't respond within the new 2026 timeframes?

Under the new CMS rules, if Anthem doesn't provide a decision within 7 calendar days for standard requests or 72 hours for urgent requests, the authorization is deemed approved. You should document the timeline and submit claims as if authorization was granted. Keep detailed records of submission dates and follow up with Anthem to obtain written confirmation.

FAQ 2: Can I appeal a prior authorization denial, and how long do I have?

Yes, you have 60 days from the denial date to file an appeal. Anthem must review appeals within 30 calendar days for standard requests and 72 hours for urgent appeals. Include new clinical information, peer-reviewed literature supporting your request, and a detailed letter explaining why the service meets medical necessity criteria. Use the Anthem Provider Portal for faster appeal submission and tracking.

FAQ 3: Do I need separate prior authorization for each therapy session or visit?

It depends on the service type. Physical therapy, occupational therapy, and speech therapy typically receive authorization for a specific number of visits over a defined period, such as 12 visits over 90 days. You don't need separate authorization for each visit within the approved timeframe. However, if you need additional visits beyond the original authorization, submit a new request with progress notes and updated treatment plans.

FAQ 4: How does the new 90-day continuity protection work if a patient changes Anthem plans?

If a patient switches between Anthem plans, for example from individual coverage to employer coverage, existing prior authorizations remain valid for 90 days from the plan change date. This prevents treatment disruption during plan transitions. Submit a new authorization request during this 90-day window to ensure seamless continuation of care. Document the plan change and reference the original authorization number.

FAQ 5: What documentation is most important for California rehabilitation therapy prior authorizations?

For PT, OT, and SLP services, include: First, an initial evaluation with functional baseline measurements. Second, a physician's order with specific diagnosis and treatment goals. Third, a treatment plan with measurable objectives and expected outcomes. Fourth, progress notes from previous sessions if continuing care. Fifth, functional outcome measures showing objective improvement. California specifically requires evidence-based treatment protocols and objective progress documentation.
