Answer: To bill for time-based codes, including E/M services that are dominated by counseling and/or coordination of care, the length of time must be well documented. A summary of the discussion with the patient, along with a statement of time spent, should suffice. However, each insurance company may have specific requirements, so check with your carriers to determine the most common method required in your area and document all of your services of this type very well. Dont forget also to bill prolonged service codes when appropriate. These codes are used in addition to the base E/M code, so a session would be coded 99215 for the first 40 minutes, 99354 for the next 30-74 minutes, and 99355 for each 30 minutes after that. No modifiers are necessary.
