How appeals work in Connecticut
When a Connecticut-regulated carrier denies or changes coverage, you receive an adverse determination notice. That notice must explain how to file a grievance (internal appeal) with the carrier (Conn. Gen. Stat. § 38a-591d(e)).
Internal review means the carrier reconsiders. If you still lose, many fully insured Connecticut plans can go to external review through the Insurance Department.

The usual steps
- Adverse determination — read the denial, clinical peer conference option, and grievance rights.
- Internal grievance — file with the carrier using the address or portal on the notice. You generally have 180 days from the denial to start (CID — External Review).
- Carrier decision — written outcome on medical necessity, experimental treatment, eligibility, or rescission disputes.
- External review — if still denied, see Connecticut external review.
Connecticut grievance procedures are in §§ 38a-591e–38a-591f and CID regulations (Conn. Agencies Regs. § 38a-591-7).
How long the carrier has to answer
After you file a grievance, typical timelines (confirm on your notice):
- Pre-service (care not yet provided): often within 30 days
- Post-service (claim already billed): often within 60 days
- Urgent grievances: often within 72 hours when health is at serious risk
(Connecticut OHA — My claim was denied; carrier-specific procedures)
You may be entitled to review meetings, copies of records used in the decision, and—in some cases—continuation of treatment during concurrent review grievances (§ 38a-591d(b)(1)(B)).
If the carrier is late
If the carrier does not meet utilization review or grievance deadlines in § 38a-591d, you may be deemed to have exhausted internal review and can file for external review without waiting (§ 38a-591d(g)).
Keep fax confirmations, portal screenshots, and certified mail receipts.
What comes next?
After a final internal denial, file external review within 120 days (§ 38a-591g). A $25 filing fee may apply (refunded if you win in some cases).

Key takeaway
File the internal grievance within 180 days, use every right on the denial letter (records, peer conference, expedited review), and calendar the carrier's answer date. Connecticut's external review program is binding on fully insured plans when you qualify.
