Cigna is one of the largest health insurance and managed care companies in the United States, serving millions of Californians through employer-sponsored health plans, Medicare Advantage products, and individual and family plans. The company’s scale means it generates a significant volume of litigation in California — ERISA benefit denial claims, insurance bad faith suits, and employer plan disputes are the most common categories. If you need to serve Cigna in California, the registered agent is in Sacramento and the entity identification requires some care.
The Correct Legal Entity
The correct entity for most California health insurance litigation is Cigna Health and Life Insurance Company. This is the primary insurance underwriting subsidiary of The Cigna Group (the parent holding company, formerly Cigna Corporation) and the entity that issues most Cigna health insurance policies in the United States.
Do not confuse the following:
• The Cigna Group (formerly Cigna Corporation) — This is the publicly traded Delaware holding company. It is not the insurance-issuing entity and is generally not the correct defendant in coverage disputes.
• Connecticut General Life Insurance Company — Another Cigna subsidiary that issues some Cigna-branded products. If your client’s plan documents identify the insurer as Connecticut General, verify whether to name Cigna Health and Life Insurance Company, Connecticut General, or both.
• Cigna HealthCare of California, Inc. — Cigna’s HMO subsidiary that operates in California. For HMO-specific claims involving California network plans, this entity may be the correct or additional defendant.
For ERISA-governed employer plans, the correct defendant may be the plan itself (named as a separate entity) in addition to or instead of Cigna as the insurance company or claims administrator. Review the plan documents carefully to determine whether Cigna is acting as an insurer, a third-party administrator, or both.

What Documents Are Commonly Served
Cigna’s California litigation is concentrated in health coverage and employer benefits disputes:
• ERISA Section 502(a) benefit denial complaints — The most common category of Cigna litigation in California involves claims brought under the Employee Retirement Income Security Act of 1974 for denial of health insurance benefits. ERISA preempts most state law claims for employer-sponsored plans, channeling those disputes into federal court. Typical claims involve denials for mental health treatment, substance use disorder treatment, specialty procedures, and high-cost medications.
• Mental health parity complaints — The federal Mental Health Parity and Addiction Equity Act (MHPAEA) requires that mental health and substance use disorder benefits be no more restrictive than comparable medical/surgical benefits. Class action and individual claims alleging that Cigna’s utilization review criteria for behavioral health violate parity requirements are an active litigation category.
• Insurance bad faith complaints — For non-ERISA plans (individually purchased or fully insured plans not subject to ERISA preemption), California recognizes bad faith tort claims for unreasonable denial, delay, or investigation of benefits. These are filed in California state court.
• Employer plan disputes — Claims by employers and plan participants challenging Cigna’s administration of self-funded employer health plans, including improper claim denials, coordination of benefits errors, and subrogation disputes.
• Subpoenas for claims records — Attorneys in personal injury, workers’ compensation, and medical malpractice cases subpoena Cigna for claims histories, explanation of benefits (EOB) records, and utilization review files.
How We Handle It
CSC at 2710 Gateway Oaks Drive is a location we serve regularly. For Cigna service, the entity name verification step is important: we ensure the proof of service identifies Cigna Health and Life Insurance Company rather than the parent holding company or a subsidiary HMO entity. For cases that require service on multiple Cigna entities — for example, naming both Cigna Health and Life Insurance Company and Cigna HealthCare of California, Inc. — we handle each service separately and provide individual proofs of service.
