Billable units are for time spent delivering a case management service. That service may
occur face-to-face with the beneficiary or may consist of telephone contacts or mail or e-mail
contacts necessary to ensure that the beneficiary is served. Billable units may not be billed
for such things as time spent traveling to a beneficiary to provide a case management service.
However, the case management rate can factor in the cost of non-productive time associated
with such things as case manager travel time and costs associated with mileage (in a cost-
based payment methodology, by allocating such costs among all of the productive time
increments). It may also include the actual writing of case notes, time documenting social
history and writing the information gathered for the case file for the development of a
specific care plan; and the gathering of information and the actual documentation. The state
may also document non-productive time by providing evidence of State or private agency
policies regarding sick leave, vacation leave, paid holidays and training requirements. Any
other non-productive time must be documented via use of a CMS approved time study.
Several States have inquired as to what practices should be employed to ensure that no TCM
provider is paid for more 15 minute units then they can feasibly deliver. One state intends to
require documentation from each Target Case Manager and signed by his/her supervisor
certifying the number of hours each day that a TCM was available to provide TCM services.
The monthly summary of this data will be compared to the number of 15 minute units of
service that were billed and paid. Billing units must be equal to or less than the number of
available 15 minute units of time. This is an acceptable practice and States should also
consider whether the rate has been developed to account for non-productive time, the number
of billable units per case manager cannot be greater than the amount of productive time
identified through the rate setting methodology. For example, if the rate is adjusted to
account for one hour a day of non-productive time, the case manager (assuming an 8 hour
day) could only bill for 28, 15 minute units which is equal to the 7 hours of productive time
identified by the state in constructing the rate.
54) What constitutes an approved, statistically valid time study?
Answer
Recognizing the necessity of using a sample to develop claims, OMB Circular A-87 permits
the use of “substitute systems” for allocating costs to federal awards in place of activity
reports. Any such sampling methodology, or time study, must be approved by the funding
agency (CMS). These time studies may utilize random moment sampling, case counts, or
other quantifiable measures of employee effort, as long as they are deemed by CMS to be
statistically valid and capture all paid time, even if it is not allowable to Medicaid. Required
elements for a time study include the following: defining the sample universe, developing
the activity codes, designing the sampling methodology, retaining required documentation,
conducting training, ongoing oversight and monitoring, and developing a validation protocol.
Surveys will not be sufficient. For private providers, states may wish to consider developing
market-based rates as an alternative to documenting nonproductive time. Any such time
study would be approved by CMS outside of the State plan amendment review process, and
reference therein. The State’s public assistance Cost Allocation Plan must also reference the
CMS approved time study by way of amendment.
55) With respect to 441.18(a)(7) and “units of case management received”, does there have
to be a note in the file for every 15 minute code billed or can the documentation
