Calculating time units

  1. Default Calculating time units
    Exam Training Packages
    When calculating time units for a 99 minute service, you get 6 full 15 minute segments. What do you do with the additonal 9 minutes?

    99 minutes divided by 15 minutes gives me 6.6. Does one normally round up or down in this situation and is there any written guideline on how this is calculated?

    Just learning here and need to know for an assignment.

    Thanks

    when calculating time, you must be one half of the required time into the next segment to count it. so for a 15 minute service a minumum of 8 minutes to even start, then 8 minutes into next segment for it to count so 15 plus 8, 23 minutes minimum for 2 units.
    8- 22 = 1 unit
    23 - 37 = 2 units
    38 - 52 = 3 units
    53 - 67 = 4 units
    68 - 82 = 5 units
    83 - 97 = 6 units
    98 - 112 = 7 units
    therefore for 99 minutes of a 15 minute service you bill 7 units.

    Debra,

    Thank you for your reply. I asked because I had put 7 units for 99 minutes in my class and it was counted wrong.

    I try not to let these things bother me, but they do.

    You need to ask why it was counted wrong. This chart comes from the CMS manual. So show the instructor the chart of time units and see what he/she says.

    Debra,

    I think I found it. http://www.cms.gov/transmittals/downloads/R1951CP.pdf

    I searched before I asked and wasn't coming up with anything, then I thought to search by copying the time table you provided and I found it that way.

    Is this the one you are referring to?

    Thanks!

  9. Default Incorrect table being referenced in these posts
    Hello:
    The table being referenced in these postings is for use with rehab therapy billing and not for anesthesia billing. If you review billing for anesthesia time, anything that is over 7.5 minutes is given another unit of time not the ranges as referenced in this table.

    Thank you so much for pointing out that the above link is not the correct one, it is greatly appreciated.

    Does anyone have a written reference for how to calculate anesthesia time units that are not in exactly 15 minute increments?
