New CPT Code 99439 Replacement for CPT G2058

• Use 99439 in conjunction with 99490 and Chronic care management services of less than 20 minutes duration, in a calendar month, are not reported separately

• Do not report 99439 more than twice per calendar month

Tips

The total duration of the staff care management services must meet the time listed in the code descriptor to be reported. 

For instance, for services totaling 40 minutes, you may report 99490 (first 20 minutes) and +99439 (additional 20 minutes). 

But for 39 minutes, you should report only 99490. A total of 39 minutes does not meet the requirement of 20 minutes for 99490 and another 20 minutes for +99439.
