Why had NHIA identified CPT code 99539 (“unlisted home visit service or procedure”) to code a home nurse visit for provision of home infusion therapy (HIT)?
We had searched throughout the 2002 HCPCS and CPT code sets for a specific “per visit” HIT nursing code, but we found no such code existed. Hence, the first version of our coding standard used 99539. In 2003, added to HCPCS and CPT are nurse visits codes as a result from NHIA’s HIEC activity. Accordingly, the current version of the coding standard no longer includes 99539.
