Defines Providence Health Plan's coverage stance for thermal and non-thermal intradiscal procedures for treatment of low back pain for applicable company commercial products; describes clinical context, evidence review, and coding/regulatory notes. Affects providers submitting claims or prior authorizations to Providence Health Plan and affiliated companies.
No material clinical or coverage changes in this revision.
Coverage Criteria
inv-01: Thermal intradiscal procedures — Not medically necessary
Thermal intradiscal procedures are considered not medically necessary for treatment of low back pain, including but not limited to the following:
Listed procedures are examples and include but are not limited to those named.
inv-02: Non-thermal intradiscal procedures — Not medically necessary
Non-thermal intradiscal procedures are considered not medically necessary for treatment of low back pain, including but not limited to the following:
Listed procedures are examples and include but are not limited to those named.
inv-03: Overall coverage stance
Coverage determination
Additional large RCTs with long-term follow-up are needed.
For Oregon Medicaid/OHP members, the OHP Prioritized List and Oregon Administrative Rules (OARs) take precedence for coverage determinations. Providence Health Plan medical policy criteria may be applied only when there are no applicable OAR/OHP criteria for the requested intradiscal service.
For Medicare members, this Company policy may be applied only when directed by a separate Medicare policy. Note that investigational services are considered not medically necessary for Medicare members under the Medicare-directed application.
All intradiscal procedures are performed with radiologic or fluoroscopic guidance. When radiologic or fluoroscopic guidance is performed in conjunction with intradiscal procedures, that guidance is considered not covered as an ancillary service.
Thermal intradiscal procedures are considered not medically necessary for treatment of low back pain, including but not limited to: Intradiscal Biacuplasty (IDB), Intradiscal electrothermal therapy (IDET) / intradiscal thermal annuloplasty (IDTA), Percutaneous intradiscal radiofrequency thermocoagulation (PIRFT), Percutaneous (or plasma) disc compression (PDD) / coblation, Radiofrequency annuloplasty (RA), and Targeted disc decompression (TDD).
Non-thermal intradiscal procedures are considered not medically necessary for treatment of low back pain, including but not limited to: Glucocorticoid intradiscal injections and Methylene blue intradiscal injections.
There is insufficient evidence that percutaneous thermal and non-thermal intradiscal procedures are safe and effective compared to standard surgical and non-surgical treatments for low back pain. The available literature is limited and heterogeneous, with few high-quality randomized controlled trials and no authoritative guidelines strongly supporting these procedures; therefore they are considered not medically necessary. Additional large, well-designed RCTs with long-term follow-up are needed to establish clinical utility.

Provider Actions and Requirements
Prior authorization expectation — intradiscal procedures
For applicable commercial plans, intradiscal procedures are subject to medical policy review and are listed as not medically necessary; prior authorization is recommended when such procedures are proposed.
Prior authorization for unlisted codes
If an unlisted spinal or nervous system code is submitted, the claim will be reviewed for medical necessity; prior authorization is recommended for unlisted codes representing potentially covered services to avoid post-service denial.
Conservative therapy expectation prior to surgery
Initial treatment for discogenic low back pain should include conservative measures such as pain medications, physical exercises, physical therapy, back brace, intradiscal corticosteroid injections, and/or nerve blocks before considering surgery.
- Surgical options (disc excision, spinal fusion, total artificial disc replacement) are reserved for pain not responsive to conservative measures.
Suggested documentation elements
Document the procedure type, device or probe name(s) used, indication, fluoroscopic guidance, and prior conservative treatments attempted when applicable.
- Include specific device/probe names when used (examples listed in FDA section).
- Record that fluoroscopic guidance was used.
Documentation and coding notes — fluoroscopy & unlisted codes
All intradiscal procedures are performed with radiologic or fluoroscopic guidance; unlisted codes are reviewed for medical necessity and may require prior authorization to avoid post-service denial.
- Radiologic/fluoroscopic guidance performed with intradiscal procedures is considered not covered as an ancillary service.
- All unlisted codes are reviewed at the claim level for medical necessity, correct coding, and pricing.
Denial risk — intradiscal procedures (not medically necessary)
Thermal and non-thermal intradiscal procedures are considered not medically necessary for treatment of low back pain; claims for these procedures may be denied as not medically necessary.
- Examples of thermal procedures listed as not medically necessary include IDB, IDET/IDTA, PIRFT, PDD/coblation, RA, and TDD.
- Examples of non-thermal procedures listed as not medically necessary include glucocorticoid intradiscal injections and methylene blue intradiscal injections.
Denial triggers — intradiscal procedures and fluoroscopic guidance
Intradiscal procedures and any associated radiologic or fluoroscopic guidance performed as part of intradiscal procedures are considered not covered when performed as intradiscal procedures; unlisted spine codes submitted for non-covered intradiscal services will be denied as not covered.
- Radiologic/fluoroscopic guidance is considered not covered as an ancillary service when performed with intradiscal procedures.
- Unlisted codes submitted for potentially covered services should have prior authorization to avoid post-service denial; unlisted codes for non-covered services will be denied.
Background and Context
Percutaneous thermal intradiscal procedures are minimally invasive techniques in which one or more catheters or probes are inserted into the intervertebral disc under fluoroscopic guidance to apply heat or cause controlled disruption within the disc. Examples of intended effects include coagulation of intradiscal tissue, sealing of annular tears, ablation of nociceptive fibers, decompression, or creation of focal thermal lesions. These procedures are typically performed with fluoroscopic imaging and specific intradiscal device systems and are intended as treatment options for discogenic low back pain when conservative measures have failed.

Conservative Treatment Requirements
inv-24: Conservative therapies expected prior to surgical intervention
Conservative therapies expected prior to surgical intervention
Surgical treatment is offered only if pain is not responsive to these conservative measures; examples of surgical options include disc excision, spinal fusion, or total artificial disc replacement.
inv-25: (additional conservative-treatment criteria placeholder)
Additional notes regarding conservative-treatment expectations and evidence context:
Ideal patient selection and the efficacy of individual procedures remain uncertain; larger, better-quality studies with long-term follow-up are needed.
Frequency and Billing Limits
Imaging Requirements
Fluoroscopy used for thermal intradiscal procedures
Thermal intradiscal procedures are described as procedures that insert catheter(s)/probe(s) into the disc under fluoroscopic guidance; fluoroscopy is noted as the imaging guidance used.
Radiologic/fluoroscopic guidance for intradiscal procedures
All intradiscal procedures are performed with radiologic or fluoroscopic guidance; such guidance is considered not covered as an ancillary service when performed with intradiscal procedures.
Not Covered / Examples
Not covered intradiscal procedures include, but are not limited to: Intradiscal Biacuplasty (IDB); Intradiscal electrothermal therapy (IDET/IDTA); Percutaneous intradiscal radiofrequency thermocoagulation (PIRFT); Percutaneous (or plasma) disc compression / coblation (PDD); Radiofrequency annuloplasty (RA); Targeted disc decompression (TDD); Glucocorticoid intradiscal injections; and Methylene blue intradiscal injections. Claims for these procedures and associated radiologic/fluoroscopic guidance performed with intradiscal procedures may be denied as not medically necessary or not covered.
