The New Hampshire Insurance Department collects data on consumer complaints against carriers. Collected data includes:
- Reason for the complaint
- Type of Coverage
- Whether the claim was confirmed
- Final disposition of the complaint
Complaints per 1,000 Enrollees: a measure of the number of confirmed complaints for every 1,000 enrollees = number of complaints, divided by average members, multiplied by 1,000.
|Carrier||Average Enrollees||Complaints per 1000||90% Confidence Interval Range|
|Aetna||316||0||0 to 1.73|
|Anthem||152,985||0.33||0.25 to 0.41|
|CIGNA||8,641||0.12||0 to 0.45|
|Harvard||83,906||0.42||0.31 to 0.52|
|United||1,210||0||0 to 0.89|
The 90th percent confidence interval can be considered when reviewing the customer complaint data. A 90th percent confidence interval means that we are 90% confident that the number of complaints per 1000 members will fall in the indicated range. (e.g. between 0.30 and 0.42 for the entire population). Larger carriers tend to exhibit a tighter confidence range.
