62322: Injection(s), of diagnostic or therapeutic substance(s) (eg, anesthetic, antispasmodic, opioid, steroid, other solution), not including neurolytic substances, including needle or catheter placement, interlaminar epidural or subarachnoid, lumbar or sacral (caudal); without imaging guidance.
M51.26: Other intervertebral disc displacement, lumbar region
Yeah, I'm stumped. I checked Noridian (our MAC) for coverage codes and M51.26 is definitely one of them (I find if it's good for Medicare, it's usually good for everyone else). Since there's only 31 or 32 diagnoses for this procedure that Noridian accepts, it's kind of hard to go wrong with it.

You may need to put a pain diagnosis first, so consider these, if warranted:
Does the patient have sciatica? M54.31 and M54.32 are both listed
Low back pain? M54.5
Postherpetic neuropathy? B02.23
Lumbar stenosis? M48.xxx
