HHSC reviews transfers made on or after February 8, 2006 across a 60-month look-back window, measured from either the application file date or the date of a program transfer request. That 60-month rule reached full effect in February 2011 (HHSC look-back policy).
A look-back period isn't a blanket rule that every past payment causes disqualification — it's simply the stretch of time HHSC examines under its transfer-of-assets policy. What actually matters within that window are the specific facts of each transaction: what was transferred, what value was received in exchange, and whether any exception applies (HHSC look-back policy).
