Coverage and Medical Necessity Criteria

Unproven / Not Medically Necessary

Listed as unproven and not medically necessary

Not medically necessary procedures: Functional anesthetic discography; Discography; Provocative discography; Epiduroscopy (including spinal myeloscopy); Chemonucleolysis; Percutaneous and endoscopic epidural lysis of adhesions are unproven and not medically necessary for the diagnosis or treatment of any type of neck, back, or spinal disorder due to insufficient evidence of efficacy.

From Coverage Rationale

Study-based eligibility and outcome criteria

Evidence-supported scenarios and trial endpoints reported in the literature (as summarized):

PA/LOA trial eligibility elements commonly used in studies: Patient with chronic low back and/or radicular pain refractory to conservative management (physical therapy, structured exercise, chiropractic, medications) and prior fluoroscopically-directed epidural steroid injections; symptoms persistent >4 months in many trials.time: >4 months in some trials

Derived from Gerdesmeyer et al. (2013) and systematic reviews

Outcomes considered clinically significant in studies: ≥50% reduction in pain (VAS/NRS) or ≥40% functional improvement (ODI or similar) at 3, 6, or 12 months is commonly used as a clinically meaningful endpoint in RCTs and systematic reviews of PA/LOA and endoscopic adhesiolysis.≥50% pain reduction or ≥40% functional improvement

Primary endpoints in multiple RCTs and systematic reviews

This Medical Policy applies only to the state of Pennsylvania. Requests for services that do not meet the criteria set forth in the Pennsylvania Access to Prior Authorization Program (PARP) will be evaluated on a case‑by‑case basis. Refer to Pennsylvania Exceptions (Pennsylvania Code Title 55, Chapter 1101) where applicable.

No randomized controlled trials or other high‑quality trials were identified in this excerpt supporting use of these procedures for the cervical spine. The National Institute for Health and Care Excellence (NICE) has concluded that therapeutic endoscopic division of epidural adhesions has limited evidence of short‑term efficacy and significant safety concerns and therefore should be used only with special arrangements for governance, consent, audit or research. Separately, the American College of Radiology (ACR) states there is no relevant literature to support discography for evaluation of subacute or chronic low back pain without red flags or management implications.

Editorial change: several Pennsylvania‑specific related policy links were removed from the References/Related Policies list effective 01/01/2025. The removed titles include Discogenic Pain Treatment (for Pennsylvania Only), Epidural Steroid Injections for Spinal Pain (for Pennsylvania Only), Facet Joint and Medial Branch Block Injections for Spinal Pain (for Pennsylvania Only), and Minimally Invasive Spine Surgery Procedures (for Pennsylvania Only).

Procedures referenced in this policy include: functional anesthetic discography, provocative discography (discography with contrast provocation), epiduroscopy (including spinal myeloscopy), chemonucleolysis (intradiscal enzymatic therapy such as chymopapain/condoliase), and percutaneous and endoscopic epidural lysis of adhesions (percutaneous adhesiolysis/epidural lysis of adhesions, including Racz‑type procedures).

The American College of Radiology (ACR) appropriateness criteria (2021 update) state there is no relevant literature to support the use of discography for evaluation of subacute or chronic low back pain in the absence of red flags or management implications. This position is cited to contextualize the limited clinical utility of discography in many common indications.

The coverage excerpt provided does not include an explicit single‑line "not medically necessary" statement within this window; however, the Coverage Rationale lists specific procedures as unproven and not medically necessary (see the policy Coverage Rationale). Providers should verify applicable federal, state, and contractual benefit plan requirements and prior authorization rules before proceeding, as those requirements govern coverage decisions.

What Providers Must Do / Prior Authorization

Prior Authorization

Pennsylvania prior authorization / PARP evaluation

This policy applies only to the state of Pennsylvania. Requests for services that do not meet criteria set in the Pennsylvania Access to Care (PARP) evaluation will be considered on a case‑by‑case basis and may be denied if nonconforming. Refer to Pennsylvania Code, Title 55, Chapter 1101 for applicable exceptions.

Policy limited to Pennsylvania — nonconforming requests evaluated case‑by‑case

Denial Risk

Evidence limitations may trigger denials

There are limitations in the evidence base for several procedures (including chemonucleolysis, functional anesthetic discography, provocative discography, epiduroscopy, and epidural lysis of adhesions). Lack of high‑quality, consistent evidence or long‑term outcomes may result in requests being denied as unproven or not medically necessary.

Procedures with insufficient evidence may be considered not medically necessary

Clinical Background and Scope

Background: These are interventional spinal procedures proposed for diagnosis or treatment of neck and back pain. Epiduroscopy uses an endoscope or flexible catheter (and sometimes laser) to visualize the epidural space and remove adhesions or fibrosis, often concluding with steroid administration into the epidural space. Epidural lysis of adhesions (LOA) or percutaneous adhesiolysis is a mechanical and/or chemical disruption of epidural scar tissue intended to relieve radicular or low back pain. Discography includes provocative discography (contrast injection to reproduce pain) and functional anesthetic discography (intradiscal anesthetic to assess pain source) as diagnostic procedures. Chemonucleolysis refers to intradiscal injection of proteolytic enzymes (for example, chymopapain or condoliase) intended to dissolve herniated nucleus pulposus as a minimally invasive alternative to surgery.

Conservative Therapy Requirements Before Intervention

Failure of conservative therapy — literature context

Failure of conservative therapy is commonly noted in the clinical literature but no explicit payer-required duration is stated in the provided text.

Literature context: Chemonucleolysis studies typically enrolled patients who had failed conservative management (medications, physical therapy, epidural/nerve block therapies) prior to intervention; however, individual trials and reviews do not define a standardized required duration for conservative care that would serve as a payer-mandated threshold.

Derived from chemonucleolysis study descriptions and trial inclusion statements

Failure of conservative therapies prior to considering PA/LOA

Multiple guidelines and trial reports indicate percutaneous adhesiolysis/epidural LOA are considered after failure of conservative therapies.

Conservative therapies expected before PA/LOA: Patients considered for percutaneous adhesiolysis (PA) or epidural lysis of adhesions (LOA) in the literature have generally failed conservative management including physical therapy, structured exercise programs, medications, chiropractic care, and fluoroscopically-directed epidural steroid injections.

Frequency and Repeat Procedure Considerations

Applicable codes and frequency guidance

Coding availabilityApplicable CPT codes are listed in the policy (e.g., 62264, 62290-62292, 64999, 72285, 72295)

Frequency limits in documentNo explicit numeric frequency limits provided in this portion of the policy

Billing noteListing of a code does not imply coverage; check federal, state, or contractual requirements

Percutaneous adhesiolysis / epidural LOA — frequency note

Repeat proceduresEvidence suggests adhesiolysis procedures often must be repeated more than once per year to maintain benefit (no formal limit specified)

Evidence contextStatement based on systematic reviews and assessments noting repeat procedures in practice

Imaging and Radiologic Supervision Requirements

Documentation Required

Fluoroscopy / radiologic supervision required for epidural lysis, discography, chemonucleolysis

Epidural lysis procedures, discography, and chemonucleolysis are described as performed with fluoroscopic guidance and require radiologic supervision/interpretation when imaging is used.

Discography radiologic supervision and interpretation CPTs: 72285, 72295
Percutaneous lysis described with radiologic localization

Note

Imaging referenced: MRI and fluoroscopic epidurography in studies

Studies of epiduroscopy and PA/LOA reference MRI and fluoroscopic epidurography to assess anatomy, and some trials used these imaging modalities in evaluation and follow‑up.

Note

Imaging‑based procedures commonly included in clinical studies

Services Not Covered / Not Supported

Not covered: The policy lists the following procedures as unproven and not medically necessary for diagnosis or treatment of any neck, back, or spinal disorder due to insufficient evidence of efficacy: functional anesthetic discography, provocative discography, epiduroscopy (including spinal myeloscopy), chemonucleolysis, and percutaneous and endoscopic epidural lysis of adhesions.

NICE position: A 2010 NICE statement concluded evidence for therapeutic endoscopic division of epidural adhesions is limited to short‑term efficacy and that there are significant safety concerns. NICE recommends this procedure be used only with special arrangements for clinical governance, consent, audit or research (i.e., within research or special arrangement frameworks).

No additional not‑covered items are explicitly listed in the provided excerpt beyond those named in the Coverage Rationale. Providers should consult the full policy, federal/state/contractual benefit plan language, and prior authorization tools as needed for the complete list of exclusions and applicability.
