EmblemHealth Interventional Pain Coverage Update

Medical Necessity and Coverage Criteria

inv-01: Trigger Point Injection - Initial Coverage

Trigger point injections are considered medically necessary when ALL of the following are met

Trigger Point Injection Criteria: Conservative therapies including pharmacologic therapies (e.g., NSAIDs, muscle relaxants, acetaminophen), nonpharmacologic modalities, and physical therapy have been tried and failed; Symptoms lasting >= 3 months; Trigger point injections are provided as part of a comprehensive treatment plan (not in isolation) that includes pharmacologic, nonpharmacologic and physical therapy modalitiesSymptoms >= 3 months

From trigger point section

inv-02: Peripheral Soft-Tissue Injection - Initial Coverage

Injections indicated to relieve substantial pain and/or significant functional disability when conservative measures have failed or are not appropriate

Tendon/ligament/ganglion/carpal/tarsal injection criteria: Other conservative therapy has not provided acceptable relief, is contraindicated, or is not appropriate; There is a reasonable likelihood that injection will significantly improve pain and/or functional disability; For carpal tunnel, injection may be indicated for mild-to-moderate symptoms when conservative measures have failedN/A

From tendon sheath/ligament section

inv-03: Epidural/Intrathecal Injection - Diagnostic & Therapeutic

Epidural/intrathecal injections may be covered for diagnostic or therapeutic indications when documented conditions are present

Diagnostic indications: Suspected radicular pain and/or neurogenic claudication; low back pain with substantial imaging abnormalities (e.g., central disc herniation, severe degenerative disease, central spinal stenosis); documented pain rating >= 3/10 with functional impairment; to differentiate level of radicular nerve root pain or radicular vs non-radicular pain; to evaluate discrepancy between imaging and clinical findings; to identify source in multi-level compression or prior operative sitePain >= 3/10

Diagnostic indications list

Therapeutic indications: Radicular pain resistant to other therapies or when surgery is contraindicated; post-decompressive radiculitis or post-surgical scarring; monoradicular pain confirmed by diagnostic blockade when surgically correctable lesion cannot be identified; acute herpes zoster/post-herpetic neuralgia; spinal stenosis; advanced cancer pain; nerve root injuries and neuropathic pain; spinal cord myelopathy; epidural scarring; multiple rib fractures; vertebral compression fractures; management of intractable spasticity after failed medical treatmentN/A

Therapeutic indications list

inv-04: Paravertebral (Facet) Block - Diagnostic and Therapeutic

Facet joint/medial branch blocks used diagnostically; therapeutic/denervation considered based on double-comparative block responses

Facet block diagnostic criteria: Patient presents with axial back/neck pain without a strong radicular component; pain aggravated by hyperextension; focal tenderness at suspected level; perform double-comparative local anesthetic blockade (intra-articular small volume or medial branch block) with documented pre- and post-procedural pain scoresN/A

Diagnostic process and documentation

Follow-up therapeutic criteria: If significant relief occurs, document degree and duration of relief and improvement in function; repeat block only if pain returns with deterioration in function; if double-comparative blocks give significant but short-lived relief, consider denervationN/A

Therapeutic pathway after diagnostic blocks

inv-05: Diagnostic facet joint/nerve blocks

Diagnostic paravertebral/facet joint blocks — Covered when ALL of the following are met

Diagnostic facet block criteria: Back and neck pain not improving after at least 3 months of conservative therapy (e.g., NSAIDs, PT); predominantly axial pain without radiculopathy or neurogenic claudication; clinical assessment localizes pain to facet joint (other sources like fracture, tumor, infection excluded); pain level >= 6/10 recurrent or constant; pain causing functional limitationsee individual node texts

Repeat injection only if pain returns with functional deterioration; may require injection of 2-3 adjacent levels

inv-06: Therapeutic facet/nerve blocks

Therapeutic paravertebral/facet joint/nerve blocks — Covered when ALL of the following are met

Therapeutic facet/nerve block criteria: Patient had relief with controlled diagnostic blocks (combined response from two blocks) lasting several weeks to months OR initial relief >= 80%-90% with ability to perform previously painful maneuvers and persistent >= 50% relief for a minimum of 6 weeks; injections limited to no more than once every two months for a specific region (cervical/thoracic or lumbosacral); consider adverse effects of corticosteroidssee text

If diagnostic blocks provide only short-lived relief, consider denervation instead

inv-07: Sacroiliac joint injections

Sacroiliac (SI) joint injections — Covered when ALL of the following are met

SI joint injection criteria: Chronic low back pain suspected to be secondary to SI joint dysfunction; conservative/noninvasive therapies (rest, PT, NSAIDs) have failed; diagnostic double-comparative intra-articular local anesthetic injections (2-3 ml of differing durations) demonstrate >= 75% initial pain relief and ability to perform previously painful maneuvers; steroids may be injected in addition to local anesthetic>=75% initial pain relief

Therapeutic SI joint injections reasonable if SI joint determined to be pain source

inv-08: Epidural analgesia indications

Epidural analgesia for acute postoperative or major trauma pain — Covered when ANY of the following indications present

Epidural indications: Major non-operative trauma; obstetrical care; postoperative pain after major thoracic, intra-abdominal, radical pelvic cancer, aortic, retroperitoneal or major orthopedic surgeries (e.g., hip, knee); epidural catheters are usually left in place <= 3 days unless clinically indicated otherwise

Catheters usually left <= 3 days; epidural steroids only with radiculopathy unless discogenic pain

Injections that consist solely of saline and/or botanical substances are not considered medically necessary. The policy states these agents are not supported in the peer-reviewed literature and therefore are excluded from coverage; only injections of local anesthetics and corticosteroids are covered for indicated procedures.

Dry needle trigger point injections (CPT 20560, 20561) are explicitly stated as not medically necessary for Commercial and Medicaid members due to insufficient evidence of therapeutic value; the policy references Medicare LCD guidance separately for Medicare coverage considerations.

The policy specifies that injections used on a routine periodic or continuous basis for chronic non-malignant pain syndromes are not considered medically necessary. It underscores that there is no role for a planned "series" of injections and that each injection must be individually evaluated for diagnostic or therapeutic efficacy.

Several procedures and techniques are listed as exclusions or not medically necessary due to insufficient evidence. These include acupuncture (except for specified Medicare members), joint sclerotherapy, ligamentous injections with sclerosing agents, nerve block injections for primary or secondary headache (with limited Medicare exception), and prolotherapy.

The policy identifies a number of technologies and procedures considered experimental, investigational, or unproven and therefore not supported. Examples called out include peripheral nerve stimulation/field stimulation (PNS/PNFS), Axon Therapy, electric cell signaling treatment (neoGEN/EcST), and genicular artery embolization for knee osteoarthritis.

The document includes several unlisted or unclassified codes in its coding section (for example, CPT 64999 and HCPCS J3490 for unclassified drugs). Use of these codes may trigger requests for additional documentation and could lead to payment issues if not well supported in the medical record.

The policy reiterates that dry needle trigger point injections are not medically necessary; rationale provided includes insufficient peer‑reviewed evidence of therapeutic value. Additionally, the policy emphasizes that if injections produce only temporary relief, alternative treatments should be considered rather than repeated routine injections.

When imaging guidance (fluoroscopy or CT) is the standard of care for a given procedure (for example, transforaminal epidural or paravertebral/facet injections), performing the injection without appropriate imaging is considered inappropriate and not reasonable or necessary. The policy further states that documentation must support use of image guidance when billing the associated imaging codes.

Peripheral nerve blocks for the treatment of diabetic neuropathy are specifically noted as not considered medically necessary, based on lack of supporting evidence in the peer‑reviewed literature and specialty guidelines.

No additional explicit not medically necessary statements are present in the cited coding/material sections beyond those already summarized elsewhere in the policy.

Documentation, Prior Authorization, and Billing Guidance

Prior Authorization

Prior authorization and documentation

The treating physician or primary care provider must submit clinical evidence that the patient meets criteria for the requested diagnostic or therapeutic pain management procedure. Without sufficient documentation, EmblemHealth will not be able to properly review requests for prior authorization.

Prior authorization may be required for certain high-cost injectables and select HCPCS/professional service codes; submit full clinical records, prior conservative therapy documentation, and prior test results as applicable.

Denial Risk

Anesthesia denial risk

Anesthesia services billed on the same day as a pain management procedure (e.g., interventional injection) will be denied unless medical necessity for the concurrent anesthesia is clearly substantiated in the medical record. When billing separate anesthesia or sedation with an interventional pain service, document the specific medical indications and use appropriate modifiers (e.g., modifier 59) only when distinct procedural circumstances meet modifier guidance.

Required Trials and Documentation of Conservative Care

inv-53: Document prior conservative management failure or contraindication

Document prior conservative management failure or note a contraindication before proceeding with trigger point injections

Conservative management documentation for trigger point injections: Conservative therapies (pharmacologic, nonpharmacologic, and physical therapy) must have been tried and failed prior to trigger point injection unless a contraindication or acute disabling situation exists; symptoms should have persisted >= 3 monthsSymptoms >= 3 months

From conservative treatment requirements

inv-54: Document failure of conservative measures prior to diagnostic/therapeutic injections

Document failure of appropriate conservative measures prior to diagnostic or therapeutic injections

Conservative therapy requirement for diagnostic/therapeutic injections: Diagnostic facet joint blocks require at least 3 months of conservative therapy (e.g., NSAIDs, physical therapy) prior to consideration; SI joint injections require failure of conservative/noninvasive treatments (rest, PT, NSAIDs) before diagnostic/therapeutic injections

Scheduling and Frequency Constraints

Trigger point injection combinations (20552, 20553) — frequency limit

Combination frequency denialAny combination of CPT 20552 and 20553 billed more than 3 times in a 90‑day period will be denied

Relevant codesCPT 20552, CPT 20553

Related limitationDry needle trigger point injections (20560, 20561) are not medically necessary for Commercial and Medicaid

Therapeutic facet joint/nerve injections — frequency per region

Maximum frequency per regionTherapeutic facet joint/nerve injections: no more than once every two months for a specific region (cervical/thoracic or lumbosacral)

Image Guidance Standards

Documentation Required

Fluoroscopy or CT required for transforaminal epidurals and paravertebral/facet/medial branch blocks

Transforaminal epidural injections and paravertebral (facet) joint or medial branch blocks must be performed with fluoroscopic or CT imaging guidance.

Codes listing image guidance include 64479–64484 and 64490–64495
Document imaging guidance when billing corresponding codes (e.g., 77003, 77012)

Documentation Required

Fluoroscopy or CT required for transforaminal, paravertebral, denervation and SI joint procedures

Transforaminal epidural injections, paravertebral facet/nerve injections, denervation procedures, and sacroiliac joint injections require fluoroscopic or CT guidance; document the reason for CT if chosen over fluoroscopy.

Standard of care: fluoroscopy or CT for these procedures
Rationale for CT use must be documented in the medical record

Key Definitions

Trigger point / Myofascial pain syndrome — definition and essentials

Definition of trigger point/myofascial pain syndromeSelf-sustaining hyperirritative foci in skeletal muscle producing a referred pain pattern; diagnosis requires history and physical exam findings (focal tenderness, taut band, reproduction of referred pain)

Clinical role of injectionsTrigger point injections (local anesthetic ± steroid) are part of comprehensive treatment when conservative measures fail

Minimum symptom durationSymptoms usually present for ≥3 months for consideration of trigger point injections

Epidural / Intrathecal injections — definition and purpose

Definition/purposeEpidural and intrathecal injections are injections into the epidural or subarachnoid space used for diagnostic and therapeutic purposes for acute and chronic pain and spasticity

Clinical uses

Clinical Background

Myofascial trigger points are described as focal, hyperirritable loci within skeletal muscle that can produce local and referred pain patterns. Diagnosis relies on history and physical exam findings (for example, focal tenderness and a taut band), and trigger point injections (typically local anesthetic ± steroid where indicated) may be considered when conservative therapies have failed and symptoms have persisted for ≥ 3 months.

Services Not Considered Medically Necessary

Summary of items not covered: the policy explicitly lists dry needle trigger point injections (CPT 20560, 20561) and injections consisting solely of saline and/or botanical substances as not medically necessary. Additional exclusions include several procedures deemed experimental or unsupported (see exclusions and limitations sections).

Not covered.
