Using Time Span Codes

by  Find-A-Code
February 24th, 2017

The date of service (DOS) is the reference point for determining the frequency of code submission and subsequent reimbursement during that period, generally if the service was provided in a different calendar month, the service would qualify for reimbursement.

 Modifiers will not override a time span code if it is billed with another code that has a partial description included in it. 

For example; 94014, 94015 and 94016 cannot be billed together or appended with a modifier.

Patient-initiated spirometric recording per 30-day period of time:

94014   includes reinforced education, transmission of spirometric tracing, data capture, analysis of transmitted data, periodic recalibration

94015   recording (includes hook-up, reinforced education, data transmission, data capture, trend analysis, and periodic recalibration)

94016   review and interpretation only by a physician or other qualified health care professional
