Professional Services Where Time Is a Primary Factor

While time has been included in the definitions of the majority of professional service codes for a number of years now, there is a difference between codes that list "typical" time and codes where time is a primary factor. Typical time noted in the code descriptors are averages that represent a range of times and are designed to assist providers with determining the most appropriate level of code.

In addition to codes that have a "typical" time component, there are a variety of professional codes where time is a primary factor in the code. However, even in cases where time is a primary component, there are differences in the requirements for utilizing these codes. It is important to review the requirements of a code prior to submitting it on a claim. Required time is the necessary time a provider spends rendering the service to the beneficiary, and the appropriate selection of the code includes a firm time basis. There are also codes within the Evaluation & Management code set that use approximate time thresholds, codes that involve a time range and codes that are "add-ons" for additional time spent rendering a service.

When selecting a code based on time, documentation must clearly reflect the time spent providing the service. The following time threshold reference tables include professional service codes from the Evaluation & Management code family with explicit minimum time requirements.
