However, the numbers came with several qualifications.
Many states have more than one insurance market or rating area. An insurer is counted as participating in a state if it is in just one local market. Consumers in an urban area may have additional choices next year, but that does not guarantee the same options for people in rural areas who had more limited choices this year. The administration did not disclose the number of plans in each rating area in a state.
Moreover, administration officials said, if an insurer offers its products on the exchanges of three states, that is counted as three insurers.
The numbers, through Sept. 4, do not reflect a decision last week by PreferredOne, the largest provider of coverage on Minnesota’s insurance exchange, to pull out of the state’s online marketplace.
