I guess I would not interpret these to be time-based codes where you would round to the closest hour. Those types of codes will state 'first hour' or 'each additional hour', for example, where you would need to round the fractions to the nearest whole since you are billing a unit for each hour.Thank you Thomas for your response. I did not see the language as that straightforward. For example, if I can take up to 3 days off, the whole third day is included so I wouldn't have to return until the 4th day. If I have more than 3 days to finish a project, the soonest it would be due is on the 4th day. I could not find any language in CPT that addressed the "up to and including" issue.
