Methods: Based on raw data of the previous study “Comparison of unit cost and charge of medical care for common diseases in Srinagarind Hospital during year 2003”  price of medical care was calculated from DRG.  Each Relative Weight (RW) was multiplied by 10,300 baht.  Finally, the price was compared with the hospital charge.
