I ran into the same thing. It was called SleepHealthCenters, right? I sent them a letter asking for my records and never heard back.
About a month ago I had my first visit with my sleep doc and she was able to get at my records from the defunct company in under a minute - not sure how she has access to them but she said she has access that I don't. So you might want to check with your local sleep doc.
What really made me mad, however, was last week I started getting calls from a company calling itself SleepHealthCenters saying it was time to purchase new CPAP supplies - mask, hose, filters. As if it was a prescription I had with them and they were calling me as a courtesy. I asked them how they got my information and they said that they bought the data and company name when it went bankrupt. They are basically cold-calling the customer list trying to make sales. I asked them how this wasn't a violation of my patient privacy rights and the HIPAA laws - they promptly hung up. In my opinion these guys are acting outside the law and they *will* get caught.
So, I did some research for you on the internet. SleepHealthCenters has appears to have entered receivership in Massachusetts, not bankruptcy per the following (article dated 2.6.13):
By Chelsea Conaboy, Globe Staff
A Suffolk County Superior Court judge has appointed a representative to liquidate Sleep HealthCenters’ assets and pay the company’s debts. The chain of sleep clinics closed last month, citing financial trouble partly resulting from changes in how health insurers pay for sleep-disorder testing.
The company owed Rockland Trust Company about $1.6 million under a loan agreement from 2009, when the company acquired a group of Arizona sleep clinics, according to court records. The bank filed a complaint on Feb. 1 requesting receivership, in which the judge directs an independent entity to manage the dissolution of the company. Receivership is generally seen as an alternative to bankruptcy.
The court appointee is Jacen Dinoff of the KCP Advisory Group in Burlington, who previously served as a financial consultant to Sleep HealthCenters. The company had 19 clinics, including 11 in Massachusetts.
Perhaps you can contact Jacen Dinoff directly for your records. Google KCP Advisory Group for contact info. I believe your records are also protected under HIPAA but I am not certain of the interaction between HIPAA and receivership.
