In medical, physical, and occupational therapy billing, one unit typically represents 15 minutes of direct care, but under the Medicare "8-Minute Rule," a single unit can be billed for any treatment time lasting between 8 and 22 minutes. Subsequent units are added in 15-minute increments once the previous threshold is exceeded.
Put simply, the 8 minute rule dictates that healthcare providers must provide at least eight minutes of direct, face-to-face patient care to bill for one unit of a timed service. Anything less than that doesn't qualify as billable time.
A billable unit for a 15-minute increment code is 8-22 minutes or any multiples of this time range: 8 – 22 minutes equals 1 unit. 23 – 37 minutes equals 2 units. 38 – 52 minutes equals 3 units.
The Medicare 2-Midnight Rule is a Centers for Medicare & Medicaid Services(CMS) guideline for hospital admissions, stating that if a doctor expects a patient to need hospital care crossing at least two midnights, the stay generally qualifies for Medicare Part A inpatient payment;
The SI unit of time is the second, which has been further accurately defined as “the time interval equal to 9192631770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium-133 atom (13th CGPM, 1967).” In any case, the unit second is often ...
Billing in 15-Minute Increments Chart
A task that takes 15 minutes is billed at . 25 hours, 30 minutes is . 5 hours, and 45 minutes is . 75 hours.
You can bill one or both of two critical care codes:
In this case, the total billable time equals 50 minutes (35 + 15). Divide 50 by 15 for a result of 3.3, leaving 5 remaining minutes. For this session, the therapist can only bill Medicare for 3 units since the remainder of 5 minutes is less than the 8-minute rule.
In this case, 45 minutes is equal to 0.75 decimal hours. In addition, you can also use the table to convert from decimals back into minutes and hours, by simply finding the decimal number in the “Decimal” column and then following it across to the left.
50 minutes is 3000 seconds. Time conversion involves understanding the relationship between hours and minutes. Since 1 minute is equivalent to 60 seconds, converting minutes to seconds is a straightforward multiplication process.
The 30 minutes portion is expressed as . 50 because 30 minutes equals 1/2 hour or . 50 hours in decimal format. Payroll hours are almost always reported in decimal hours.
The most common units are the second, defined in terms of an atomic process; the day, an integral multiple of seconds; and the year, usually 365 days. The other units used are multiples or divisions of these three.
An hour is a unit of time — it's sixty minutes, 3,600 seconds, or the length it takes the long hand on your watch to move in a full circle.
38 to 52 minutes = 3 units. 53 to 67 minutes = 4 units. 68 to 82 minutes = 5 units. 83 to 97 minutes = 6 units.
For example, if you spent 25 minutes on therapeutic exercises, you would bill two units for code 97110. Untimed codes, such as code 97014 (electrical stimulation), are billed once regardless of how long the service was performed during the session.
