Blue Cross and Blue Shield of Arizona Timely Filing Limit

The most important thing to confirm with Blue Cross and Blue Shield of Arizona is not just the number of days, but also what event starts the clock. Some payer documents measure from date of service, some from discharge, and some publish different rules for corrected claims or appeals.

At a glance

• Timely filing varies substantially by line of business. For Health Choice Medicaid, initial claims are generally 6 months from date of service for both contracted and non-contracted providers, with special rules when HCP is primary; corrected claims are generally 12 months from date of service. For Health Choice Pathway, contracted and non-contracted limits differ. For commercial/FEP provider grievances, AZ Blue allows written grievances no later than one year after denial/notification or date of occurrence, but that is a grievance deadline, not necessarily a claim filing deadline.

Initial claim filing limits

• Health Choice Medicaid: 6 months from date of service for non-contracted and contracted providers; if HCP is primary, claim timeliness changes to 7 months from date of service or eligibility date.
• Health Choice Pathway: non-contracted initial claim 12 months from date of service; contracted initial claim 6 months from date of service.
• Commercial/FEP: claim-specific timely filing limits are not clearly stated in the retrieved official provider pages; use plan-specific guidance / operating guide.

Corrected claim filing limits

• Health Choice Medicaid: 12 months from date of service.
• Health Choice Pathway: non-contracted corrected claim 12 months from date of service; contracted corrected claim 18 months from date of service.
• Commercial/FEP: the retrieved grievance page notes claim issues may be grieved, but corrected-claim filing limits were not clearly surfaced in the sources reviewed.

Appeal and reconsideration deadlines

• Health Choice Medicaid: dispute deadlines shown as 60 days from claim determination or 12 months from end of DOS; second-level dispute 30 calendar days after dispute decision.
• Health Choice Pathway: dispute 120 days from date of claim determination for non-contracted providers; contracted providers 18 months from DOS (end) for dispute, with second-level dispute 60 days after decision or 18 months from DOS (end) depending on path shown.
• Provider grievances (commercial/FEP and other payment/admin issues): written request no later than one year after denial or other notification, or date of occurrence if no notification; first-level decision in 60 calendar days; second-level request within 60 calendar days after first-level determination.

Trigger basis and caveats

• Health Choice pages distinguish date of service, eligibility date, date of claim determination, and date of occurrence.
• Provider grievance deadlines are triggered by denial/notification or occurrence, not DOS.
• Some limits differ for contracted versus non-contracted providers and by plan prefix/line of business.
• Timely filing is highly plan-specific and can differ from grievance/dispute deadlines.
• The commercial provider grievance page explicitly says no claim corrections are permitted after a grievance is filed.
• The sources retrieved did not surface a single universal timely-filing rule for all AZ Blue products.
