If two separate procedures are done through two incisions (e.g., a breast augmentation and an abdominal liposuction), how is the duration of the breast surgery calculated? 3/5/2008

See the Protocol section of the SSI Reporting Manual. Under denominator data it states, “If more than one MHIRS procedure is performed during the same trip to the OR, a record is generated for each operative procedure.” In the instance cited above, the ASC would note the incision time to closure time for the breast augmentation.
