Adjusted cost of multiple procedures (P) cost of OMFS (M) and cost of tooth and periodontium (D) GA = general anesthesia, Number of procedures = total procedures in one visit, CC = complication and comorbidity Complexity = level of complexity (1 = simple procedure, 2 = complex procedure, 3 = multidisciplinary or complicated procedure) LOS = length of stay (LE21 = less than and equal to 21, GE22 = more than 21).
