Hi There,
I do a lot of lab coding. The PSA lab test needs to linked first with a definitive dx code such as N42.9, Disorders of the Prostate, or dx blocks of N40 or E29 or N52 per pt. documented problem from the doctor s notations or assessment. Or perhaps with the provider supported documentation requiring dx blocks of N48,N52, N40, E29 Etc.. Physicians are to list the reason why they order the lab test , but I think some of the doctors feel if the lab test definition is telling you what they are searching for till results come back to see more inflammatory problem. So PSA lab test using terms prostate is letting you know this is the area (unspecf dx of this prostate category to use this dx code. I always use N42.9 linked with the lab PSA unless doc notes tells me something differ from his assessment. I'd use a Z code last(Z13.89, Z12.5, Z11.3 ) and one of the N42 or other definitive dx code from doctor as first dx code to link to the PSA lab. UNLESS it is a first listed Z dx code according to what doc is searching .As example dx Z01 block maybe the doc does PSA lab for part of annual physical on men. Also check the protocol for your office too. That G code is to be billed only for Medicare payers, I hope doc selects PSA lab CPT of 84153, 84152, or 87426. sometime spur doc willuse PSA lab for checking for STD look at dx blocks A52-A65 and link Z11.3
I hope I have helped you.
