Amount of Lamina Removed for a Laminectomy

Question:

I'm pretty new to neurosurgery coding and could use some help. Is there a specific amount or percentage of lamina that must be removed in order to code 63047?

Answer:

No. Surgeons usually try to remove as little lamina as possible – just enough to relieve pressure on the nerve. A specific amount does not need to be documented.
