The so-called segment A consists of hospital services for which regulated prices are derived from a global hospital budget. The segment B consists of hospital services where prices are freely negotiated with health insurers, and typically comprise less complex services (e.g. knee and hip replacements). The share of segment B has increased from less than 10% in 2005 to more than 30% in 2011 and 70% following the 2012 reform (described below). At the same time, real prices in the segment B have declined, reflecting the increased bargaining power of health insurers (Table 7).
