Insurance expires during staged breast reconstruction surgery after mastectomy

[sb0914]

After having a bi-lateral mastectomy due to breast cancer, my health insurance will expire. Since breast reconstruction is considered a staged process, will the reconstruction be covered. Here's my situation: Mastectomy done October 2011, tissue expanders were inserted at that time as well. Radiation began in Dec 2011, and reconstruction should follow in Feb or March 2012. However, my insurance expired on Jan 1 2012. Will the insurance company consider this a continuation of a process or will any claims after the expiration be denied? Any help is much appreciated!
