Summary
This is a routine annual policy reissue with no substantive changes to coverage criteria or medical necessity requirements for nerve fiber density testing. However, CPT codes 11100 and 11101 have been deleted and replaced with CPT codes 11102-11107, which represent updated procedural codes for skin biopsy techniques. Billing teams must update systems to use only the new CPT codes (11102-11107) for all nerve fiber density testing claims going forward.
