*Estimates are considered unreliable. Data preceded by an asterisk have a relative standard error (RSE) of 20% to 30%. Data not shown have an RSE of greater than 30%.

NOTES: Obesity is defined as diagnosis codes 278.00 or 278.01 on the discharge record. Up to four procedures were coded for each non-federal hospital stay. Data in this table are for any listed procedure; if more than one bariatric procedure is performed during the same hospital stay, it is counted only once. Procedures codes 44.31, 44.39, 44.69 define bariatric surgery. Starting with 2003 data, procedure codes 43.7, 43.89, 45.51, and 45.91 are also included. In addition to these seven codes, the 2004 data define bariatric surgery using procedures codes 44.68, 44.95, 44.96, 44.97, and 44.98. Procedure groupings and code numbers are based on the International Classification of Diseases, 9th Revision, Clinical Modification (ICD–9–CM). Data on adults age 65 and over are considered unreliable because of the small number of procedures performed and therefore are not presented. See Appendix II, International Classification of Diseases, 9th Revision,Clinical Modification (ICD–9–CM).
