At our practice we usually go by what the first listed diagnosis is for the specimen. So if dermatitis is listed prior to the cyst, we would code L30.8 & 88305. If the cyst is listed prior to the dermatitis, we would code L72.0 & 88304. I don’t believe there is a specific “rule” to follow in these scena
On occasion I have a scenario where the physician assigns two codes for one specimen, for example L30.8 and L72.0. Now L30.8 would be an 88305, and L72.0 would be an 88304, how would I decide which one to bill? I can't find much information on this topic through google so I'm stumped.
At our practice, if the dermatitis is the initial finding then 88305. If the cyst is the main finding then 88304.
