Maryland Code, Insurance § 18-104

(b)(1) If an application for long-term care insurance asks whether the applicant has had medication prescribed by a physician, the application also shall ask the applicant to list the medication that has been prescribed.

(2) If the carrier knew or should have known that the medication listed under paragraph (1) of this subsection at the time of application was directly related to a medical condition for which coverage would otherwise be denied, the policy or certificate of long-term care insurance may not be rescinded for that condition.
