CPT code 62323 documentation requirements
For accurate billing and coding of epidural steroid injections, including claims submitted to Medicaid services, it is essential to document medical necessity, imaging guidance, and the therapeutic agents administered. Below are the key documentation requirements:
Medical necessity and diagnosis
The documentation must clearly support the medical necessity of the injection. This includes a confirmed diagnosis such as lumbar or sacral radiculopathy, neurogenic claudication, disc herniation, or post-laminectomy syndrome. The clinical notes should describe the patient’s symptoms, their severity, and how they impact function or quality of life.
Conservative treatment history
The record must show that the patient has failed to respond to a reasonable trial (typically at least four weeks) of conservative, non-invasive treatments such as physical therapy, oral medications, or activity modification. If the injection is for acute herpes zoster, documentation should show that the condition is refractory to initial conservative management.
- Radiological evidence: Diagnostic imaging (e.g., MRI or CT) that correlates with the patient’s clinical presentation must be included. The findings should support the presence of structural abnormalities such as spinal stenosis or nerve root impingement at the level targeted for injection.
- Procedure details: The note must describe the site (lumbar or sacral), the type of approach (interlaminar epidural or subarachnoid), and the laterality if applicable. It should also detail the use of fluoroscopic or CT guidance, confirm needle placement using contrast, and discuss the substances injected, including dosages and volume.
- Use of imaging guidance: The documentation must explicitly state that imaging guidance was used (fluoroscopy or CT), and that contrast was administered to confirm proper epidural spread—unless contraindicated due to allergy or pregnancy. If contrast is not used, a justification must be provided.
- Medications administered: All medications injected should be listed by name, including the type (e.g., anesthetic, corticosteroid), dose, and total volume. If a mixture is used, each component must be detailed.
- Informed consent: The medical record must include documentation that the patient was informed of the risks, benefits, and alternatives, and that verbal or written consent was obtained before proceeding with the injection.
- Post-procedure assessment: The documentation should include the patient’s status after the procedure, noting any immediate effects or complications. If this is a follow-up injection, it should also include the patient’s response to prior injections.
- Functional or pain assessment: Objective measures such as a pain scale (e.g., 0–10) or functional assessment tool (e.g., Oswestry Disability Index) should be recorded at baseline and repeated at follow-up visits to assess the response to the intervention.
