HC Reform Update from Mark Sanna: Health insurers can't have different rules for when individual policies are sold for children with medical problems than for healthy kids, HHS Secretary Kathleen Sebelius said in a letter to the National Association of Insurance Commissioners. Some insurers want to allow healthy children to enroll year-round but only have a limited "open season" for ones with pre-existing conditions. Such an approach is legally questionable and "inconsistent with the language and intent" of the health care law, Sebelius wrote.
