What Is a BCBS Prefix and Why Does It Matter?
A BCBS prefix is the first three characters of a member’s ID card issued by Blue Cross Blue Shield. These three letters identify:
- The issuing BCBS company
- The member’s home state
- The type of plan
Since the Blue Cross Blue Shield Association operates through independent companies across the United States, each prefix connects to a specific regional BCBS entity.
If the prefix is entered incorrectly:
- Claims may go to the wrong payer
- Clearinghouse rejections may occur
- Payment posting delays increase
- Denials related to “payer not found” may appear
That’s why verifying prefixes before submission is a best practice in medical billing.
BCBS Prefix List AAA to AZZ – What This Range Covers
The AAA to AZZ range includes multiple BCBS prefixes assigned to different states and companies. In our table above, you will find:
- The exact 3-letter prefix
- The state linked to that prefix
- The correct BCBS company
- The type of health plan (HMO, PPO, EPO, Federal, etc.)
This structured format helps ensure:
✔ Correct payer selection in billing software
✔ Accurate electronic claim routing
✔ Fewer clearinghouse errors
✔ Faster reimbursement cycles
Before submitting claims, always perform a prefix lookup using official tools and compare it with the data in your billing system.
Why Prefix Verification Is Critical Before Claim Submission
Many new billers assume that all BCBS claims go to one payer. That is incorrect.
Each prefix determines:
- Claim mailing address (for paper claims)
- Electronic payer ID
- Eligibility verification portal
- Prior authorization requirements
If you skip prefix verification:
- ERA may not match correctly
- Claims can be rejected for invalid payer ID
- Appeals processing becomes complicated
Always verify the prefix during:
- Insurance eligibility check
- Claim creation
- Secondary claim submission
This small step prevents large revenue cycle problems.
High Search Prefixes in AAA to AZZ Range
Below are some commonly searched prefixes within this range.
BCBS Prefix AIR
| BCBS Prefix | State | Company Name | Types Of Health Plan |
| AIR | Pennsylvania | Capital Blue-Cross of Pennsylvania | PPO, HMO, EPO, Medicare Advantage |
The BCBS Prefix AIR is frequently searched by billers handling multi-state plans. When working with AIR:
- Confirm issuing state carefully
- Double-check payer ID in clearinghouse
- Verify plan type before submitting high-dollar procedures
Incorrect routing of AIR claims may result in payer mismatch rejections. Always cross-check eligibility response data.
BCBS Prefix AKG
| BCBS Prefix | State | Company Name | Types Of Health Plan |
| AKG | – | Unassigned Prefix | – |
At the time of writing, BCBS Prefix AKG is not actively assigned to a specific Blue Cross Blue Shield company. This means billers may not find active eligibility or payer routing details linked to this prefix.
If you encounter AKG on a member ID card:
- Double-check the ID card image for clarity
- Verify directly through official BCBS eligibility tools
- Confirm with the patient or employer if the ID appears outdated
- Contact the payer before claim submission
Submitting a claim without confirming an unassigned or inactive prefix can result in clearinghouse rejection or payer routing errors. Always verify before processing.
BCBS Prefix ANG
| BCBS Prefix | State | Company Name | Types Of Health Plan |
| ANG | – | Unassigned Prefix | – |
Currently, BCBS Prefix ANG does not appear to be assigned to an active BCBS issuing company.
If ANG appears during billing:
- Reconfirm the first three letters carefully
- Ensure there is no typographical error
- Perform real-time eligibility verification

Common Mistakes Billers Make With BCBS Prefixes
Even experienced billers sometimes make these errors:

Each prefix corresponds to a different company under the BCBS network.
2. Ignoring Plan Type
PPO, HMO, and Federal plans have different submission rules.
3. Not Updating Clearinghouse Payer IDs
Outdated payer IDs lead to electronic rejections.

Plan details may change mid-year.
Avoiding these mistakes improves clean claim rate significantly.
