Our office just recently began billing 80307. We have multiple locations from which urine samples are collected, but these samples are all sent to our main location for analysis, which is the location that has an active CLIA. When creating the claim, we're trying to decide if we should list the location as the place the sample was collected or the place the analysis actually happened. Most of these samples are being taken on the day our patients have an office visit, so we’re also trying to figure out if we should list the date as the day the sample was taken (the same day as the office visit) or the day the sample was analyzed (usually a day or so later after being transported). As I mentioned, we’re new to this so any thoughts or suggestions would be greatly appreciated!
