Capital Blue Cross prior authorization: how to submit a request
Capital Blue Cross prior authorization requests go through ProAuth, the preauthorization tool on Capital Blue Cross’s provider portal, Availity Essentials. Capital Blue Cross is the Blue Cross Blue Shield licensee for 21 counties in Central Pennsylvania and the Lehigh Valley, according to its homepage.
From December 1, 2026, Capital Blue Cross no longer accepts preauthorization requests by phone or fax, according to provider bulletin 2026-10-001 (October 1, 2026). A documented portal problem or a NICU patient is the only exception.
“Instead of having to login to several different portals, we only have to use Silna and they take care of the rest.”Kate G., OwnerSilna submits each Capital Blue Cross request with the records it needs.Get started

Who Capital Blue Cross covers
Capital Blue Cross is an independent licensee of the BlueCross BlueShield Association. Its portal rule covers its CHIP, HMO, PPO, POS, EPO, Federal Employee Program and Medicare Advantage plans, among others. The BCBS prior authorization guide covers the other Blue plans.
Some self-funded employer groups customize their plans with different benefits and preauthorization requirements, according to Capital Blue Cross’s Single source preauthorization list. Check the patient’s own plan before you send a request.
Submitting a request through ProAuth
Capital Blue Cross requires preauthorization requests to go through ProAuth. Provider bulletin 2026-10-001 gives these steps:
- On the Availity Essentials home page, choose Patient Registration.
- Choose Authorizations and Referrals to open ProAuth.
- Enter each CPT code as its own line. Capital Blue Cross reviews only the codes entered as authorization lines.
The Single source preauthorization list shows the services that currently need preauthorization, and Capital Blue Cross can change it at its discretion. Participating providers are responsible for getting the preauthorizations their patients need. To check whether a service needs one, call Provider Preauthorization Services at 800.471.2242, the number the Provider Manual 2026 gives for that check.

When phone and fax requests still count
From December 1, 2026, Capital Blue Cross considers a phone or fax request in two cases only, according to the bulletin:
- A documented portal issue, with a valid Availity support ticket number.
- A patient in a neonatal intensive care unit (NICU), under Pennsylvania’s Act 81.
The rule covers CHIP, EPO, FEP PPO, HMO, POS, PPO, Traditional and Comprehensive, and Medicare Advantage HMO and PPO plans.
Services other companies review
Capital Blue Cross delegates some preauthorization reviews to outside companies, according to its Provider Manual 2026. For Evolent’s services, the manual points providers to Evolent’s own site, RadMD.com.
| Company | Services it reviews |
|---|---|
| Evolent Specialty Services | Certain high-tech outpatient imaging and select cardiac imaging |
| TurningPoint Healthcare Solutions | Listed cardiac procedures and musculoskeletal surgery |
| eviCore | Molecular laboratory management |
| Prime Therapeutics | Medicare Advantage drug preauthorization, through CoverMyMeds |
Decision deadlines under Pennsylvania’s Act 146
Capital Blue Cross’s Provider Manual 2026 sets the decision times in this table.
| Plan | Standard request | Urgent request |
|---|---|---|
| Commercial, Exchange and managed care | 15 calendar days | 72 hours |
| Medicare Advantage | 7 calendar days | 72 hours |
| CHIP | 2 business days | 2 business days |
Capital Blue Cross tells the provider about missing information no later than 48 hours after it receives the request. Pennsylvania’s Act 146 of 2022, in effect since January 1, 2024, sets deadlines for insurers too: 72 hours for an urgent request and 15 days for others. A drug request is decided within 24 hours if urgent, or within two business days and no more than 72 hours if not. Medical Assistance (Medicaid) and CHIP managed care plans decide within two business days of receiving all supporting information.
Capital Blue Cross’s CHIP plan reported approving 719 of 898 standard requests for medical items and services in 2025 (80.1%), with a median decision time of five hours, in its prior authorization metrics. Capital Blue Cross says results based on limited data should be interpreted with caution.
