Laboratory Question for the Week of November 6, 2017

Laboratory Compliance Question of the Week

Question:

Which test and code are recommended for reporting hypo- or hyperthyroid states?

Answer:

According to the National Correct Coding Initiative (NCCI), free thyroxine (CPT® code 84439) is generally considered to be a better measure of the hypothyroid or hyperthyroid state than total thyroxine (CPT code 84436). If free thyroxine is measured, it is not considered appropriate to measure total thyroxine with or without thyroid hormone binding ratio (CPT code 84479).

Also, NCCI does not permit payment of CPT codes 84436 or 84479 with CPT code 84439.
