Top reasons

Timely filing (CARC 29) — Blue Shield of California documents a 365-day claim-filing window from the date of service for BlueCard claims (one business location), per the provider contract (paired RARC MA119: provider-level adjustment for late claim filing).; Missing information / submission error (CARC 16) — the BlueCard claims guide instructs providers to capture the complete subscriber ID (including the three-character prefix) and warns that incorrect or missing prefixes and identification numbers delay or return claims (paired RARCs: missing/incomplete/invalid NDC M119, charge M79, procedure M51, place of service N38).
