When a California health insurer fails to pay or contest a properly submitted CLEAN claim within the statutory deadline (generally 30 working days for paper / 30 calendar days for electronic), what is the principal financial consequence to the insurer?

Explanation

California Insurance Code §10123.13 (and §10350.7 for disability/health prompt-pay) imposes a duty on insurers to pay or contest a clean claim within 30 working days (paper) or 30 calendar days (electronic). Failure to do so causes interest to accrue automatically on the unpaid amount — generally 10% per year, or 15% for certain emergency-care claims under §10123.147 — payable to the claimant without the claimant having to request it, which is the response describing automatic interest plus potential market-conduct sanctions. Persistent violations can also trigger market-conduct examinations, fines, and enforcement actions by the CDI. The response saying the claim is forgiven and the balance shifts to the patient is wrong; the claim remains due. The response cutting the provider to fifty percent of billed charges fabricates a 50% haircut. Automatic revocation of the certificate of authority on the first missed deadline is far disproportionate; certificates of authority are revoked only for serious, sustained violations after due process. The accrual-of-interest remedy is the principal day-to-day enforcement mechanism.
