Pneumocystis jiroveci pneumonia prophylaxis not prescribed within 3 months of low cd4+ cell count below 500 cells/mm3 or a cd4 percentage below 15% for medical reason (i.e., patient's cd4+ cell count above threshold within 3 months after cd4+ cell count below threshold, indicating that the patient's cd4+ levels are within an acceptable range and the patient does not require pcp prophylaxis)

Still listed by CMS but carries a termination date, so it is not valid for a current date of service.

Terminated with effect from 2014-12-31. This code was already terminated before the earliest quarterly file on record here, so the date it was first published is not recorded on this site. CMS still lists this code in the current quarterly file - it carries a termination date rather than being removed.
