DESCRIPTION
The purpose of a lumbar epidural steroid injection is to achieve relief from nerve root irritation (i.e., radicular pain or sciatica) related to encroachment by bone or disk herniation, or by various causes of neuritis (e.g., radiation, chemical or autoimmune). The techniques are most accurately performed using fluoroscopy visualization for needle placement. The procedure may generally be safely performed in the outpatient setting. There are three basic techniques for lumbar epidural steroid injections:
Caudal (injection into the lower epidural space)
Translumbar (injection into a higher lumbar epidural space)
Transforaminal (injection along the desired nerve root)
The scientific literature does not reveal a consensus of definition for acute and chronic low back pain. The following definitions will be used for the purpose of this policy:
Acute low back pain is pain that resolves during the expected healing time of a low back injury or illness usually considered to be 6 months or less.
Chronic low back pain is pain that persists beyond the expected healing time of a low back injury or an illness, usually considered to be beyond 6 months.
It is also recognized that acute exacerbations or new acute episodes may be superimposed on otherwise chronic conditions.
POLICY
Lumbar epidural steroid injections for the treatment of acute and chronic low back pain is considered medically necessary if the medical appropriateness criteria are met. (See Medical Appropriateness below.)
Policies with similar titles: Lumbar Facet Steroid Injections for Treatment of Low Back Pain
MEDICAL APPROPRIATENESS
Lumbar epidural steroid injections for the treatment of acute and chronic low back pain is considered medically appropriate if ALL of the following criteria are met:
When performed under fluoroscopy
There is documentation of radiculopathy (by exam, imaging, or neuro-testing) which is unresponsive to conservative treatment (e.g., oral medications, rest/limited activity, and/or physical therapy)
ABSENCE of ALL of the following:
Allergy to the medication to be administered
A significantly altered or eliminated epidural space (e.g., congenital anatomic anomalies or previous surgery)
Anticoagulation therapy
Bleeding disorder
Clinically significant spinal stenosis
Localized infection in the region to be injected
Systemic infection
Other co-morbidities which could be exacerbated by steroid usage (e.g., poorly controlled hypertension, severe congestive heart failure, diabetes, etc.)
More than 3 (three) epidural steroid injections have been given without significant relief of low back pain over a reasonable length of time
ADDITIONAL INFORMATION
In order to minimize the risks from large doses of steroids, more than 4 (four) injections within a 12-month period is not generally appropriate.
