For multiple injection sites, the record must document the reason for injecting each site and substantiate that all injections were reasonable and necessary.
The medical record must document medical necessity including relevant history, physical exam, and results of pertinent diagnostic tests or procedures supporting the indication for the injection.
The procedure note must be legible and include techniques used, site(s) of injection, drugs with doses/volumes/concentrations, and pre- and post-procedural pain assessments.
When a referring/ordering physician is required, the referring/ordering physician's name and NPI must be reported on the claim; claims without a valid ICD-10-CM diagnosis code will be returned as incomplete.

Injection into tendon sheaths, ligaments, ganglion cysts, carpal tunnel, or tarsal tunnel is covered when medically necessary to diagnose or treat local pain and the medical record documents the clinical reason for the injection at each site.
Diagnostic injections to identify a painful structure are covered when performed no sooner than one week (preferably two) apart and limited to no more than two injections in the diagnostic phase.
Therapeutic injections are covered when a patient had diagnostic injections demonstrating initial pain relief of ≥75–100% with return of function and maintains ≥50% pain relief and functional improvement for at least six weeks.
Neurophysiology Evoked Potentials (NEPs) — including Somatosensory Evoked Potentials (SEPs), Brainstem Auditory Evoked Potentials (BAEPs/BAERs), and Visual Evoked Potentials (VEPs/VERs) — are covered when determined to be reasonable and necessary in accordance with LCD L34975.
Nerve conduction studies (NCS) without needle EMG (NEMG) are allowed for individuals being evaluated for carpal tunnel syndrome or tarsal tunnel syndrome when one of the following ICD-10-CM codes is reported: G56.01, G56.02, G56.03, G56.11, G56.12, G56.13, G56.21, G56.22, G56.23, G57.51, G57.52, or G57.53.
NCS without NEMG is allowed for individuals with significant lymphedema in the affected extremity when ICD-10-CM code I89.0 is reported in addition to the primary diagnosis.
