May 2026: Oscar tightens RFA threshold, TRICARE adds BVN ablation, UHC expands vertebroplasty.

1. Oscar Health CG047 v9 — RFA diagnostic-block relief threshold tightened from ≥50% to ≥80%

Affects: Cervical RFA (CPT 64633, 64634); lumbar RFA (CPT 64635, 64636).
Effective: Captured 2026-05-10; CG047 v9 superseded prior versions referenced in records dating to 2019-07-23.
Source: Oscar Clinical Guideline CG047 (v9)

This is the biggest single policy change of the month. Oscar Health's clinical guideline for facet joint injections and radiofrequency facet denervation — CG047 — quietly bumped to version 9, and the headline change is a 30-percentage-point increase in the diagnostic-block relief threshold required before therapeutic RFA is approved.

Under v8, a diagnostic medial branch block needed to produce ≥50% pain relief for the patient to qualify for therapeutic RFA. Under v9, that threshold is ≥80%. The same change applies to all four affected CPTs:

• 64633 — RFA, cervical/thoracic facet, single level
• 64634 — RFA, cervical/thoracic facet, each additional level
• 64635 — RFA, lumbar/sacral facet, single level
• 64636 — RFA, lumbar/sacral facet, each additional level

What this means in clinical practice. If you've been documenting "patient reported 50–70% relief from the diagnostic block" on Oscar prior auths, those submissions will now be denied. Document the relief percentage with a numeric pain scale (NRS or VAS) before and immediately after the diagnostic block, ideally with at least two pain entries during the 4–6 hour window post-block. If the patient genuinely had partial relief in the 50–80% range, a second confirmatory diagnostic block may be the cleanest path forward — though Oscar's policy doesn't explicitly require a dual-block protocol, the documentation strengthens the case.

The good news: this aligns Oscar with where Medicare LCDs and most major commercial payors have been heading. Aetna CPB 0016, Cigna eviCore CMM-201, and the Medicare LCDs for Novitas, Palmetto, and CGS all reference an ≥80% threshold or a dual-block protocol with ≥80% relief on the second block. Oscar's update is catch-up to the field, not a unique tightening.

Action items:

1. Update your prior-auth template language for Oscar RFA submissions to reflect the ≥80% threshold.
2. Re-train PA coordinators on numeric documentation of post-block relief.
3. Audit any Oscar RFA submissions in flight today; if they document <80% relief, consider holding for an updated diagnostic block.

2. TRICARE adds basivertebral nerve ablation (CPT 64628) per TPM Change 48

Affects: Vertebrogenic chronic low back pain patients on TRICARE Prime, Select, or Reserve Select.
Effective: 2026-01-01 (retroactive at TPM publication 2026-03-17).
Source: TRICARE Notice of CY 2026 Plan Program Changes (Federal Register, Oct 28 2025) + TPM 6010.60-M Change 48.

TRICARE has added basivertebral nerve ablation (the Intracept procedure, CPT 64628) to its covered-services list for CY 2026. The Federal Register notice is unambiguous: "Basivertebral Nerve Ablation, a procedure to relieve chronic vertebrogenic lower back pain for patients with degenerative disc disease or other spinal conditions, is covered."

This brings TRICARE in line with Medicare's coverage of BVN ablation under the LCD framework and most BCBS regional plans. The exact criteria — conservative-care duration, the Modic-changes MRI requirement, the prior-auth workflow — are not yet pulled into our database from the TPM Chapter 7 §3.7 / Chapter 4 §5.3 source text, so this record is currently flagged needs_verification in Rubrica. Expected criteria, by inference from CMS LCD parallels:

• Chronic vertebrogenic low back pain ≥6 months, refractory to ≥6 months conservative care.
• MRI within 12 months showing Modic Type 1 or Type 2 endplate changes at the level(s) to be treated, concordant with clinical exam.
• FDA-cleared device (Intracept system).
• Absence of radicular pain as primary symptom; absence of untreated structural pathology (e.g., spondylolisthesis ≥ Grade 2, severe stenosis, prior fusion at the same level).

If you have a TRICARE patient who's a BVN ablation candidate and a prior auth has been pending or denied, this is the week to re-submit. The pending record will be promoted out of needs_verification in next week's swarm once the TPM source text is pulled.

3. UHC Community Plan expands vertebroplasty / kyphoplasty coverage (CPT 22510–22515)

Affects: UnitedHealthcare Community Plan (Medicaid) members across all participating states.
Effective: 2026-05-01.
Source: UnitedHealthcare Community Plan Medical Policy Update Bulletin: March 2026

UHC's Community Plan Medical Policy Update Bulletin published a new policy effective 2026-05-01 covering percutaneous vertebroplasty and kyphoplasty across the full CPT family — 22510, 22511, 22512, 22513, 22514, and 22515. This touches both interventional pain (the IS catalog uses 22510-22515 for vertebral augmentation) and ortho spine (where kyphoplasty often falls under spine-surgery PA workflows).

The full criteria text needs to be pulled from the bulletin PDF — that's queued for a follow-up swarm next week. The high-confidence read from the bulletin index is that prior authorization is required and the standard vertebral-compression-fracture criteria apply (acute or subacute fracture, conservative care trial, imaging confirmation). For Community Plan submissions, expect the criteria to track Medicare's NCD on vertebroplasty/kyphoplasty closely.

4. UHC announces ~30% additional prior-auth elimination by end of 2026 (administrative)

Affects: UnitedHealthcare commercial members nationally.
Announced: 2026-05-05.
Source: UnitedHealthcare press release

This isn't a coverage policy change — it's an administrative announcement. UnitedHealth Group said on May 5 that it will eliminate prior-authorization requirements for an additional ~30% of services by end of 2026. Named categories include select outpatient surgeries, certain diagnostic tests (echocardiograms specifically called out), certain outpatient therapies, and chiropractic care.

The full per-CPT list of affected codes will be published at UHCProvider.com before changes take effect. For interventional spine, pain management, ortho spine, and orthopedics, this is potentially a meaningful workflow shift — but until the per-CPT list is published, there's nothing to act on. We're monitoring UHCProvider.com weekly and will publish the diff in the digest the moment the list goes live. If you're a UHC-heavy practice, this is the announcement to budget against: expect the 2026 H2 prior-auth load to be lighter, but plan for an audit-and-rework cycle as the transition rolls out.

What to watch for in June

Three things on the radar for the next swarm cycle:

• CMS Q3 2026 MPFS quarterly file. CMS typically publishes the RVU26C quarterly file mid-to-late June for July 1 effective date. We'll diff it against fees_2026.json and flag any CPT with a rate change >5%.
• CMS Q3 2026 OPPS / ASC Addendum. Same cadence — usually mid-June for July 1 effective. Updates ASC and hospital-outpatient facility rates.
• Carelon Interventional Pain Management guideline (Doc ID MSK01-0626.1) goes live 2026-06-14 for Anthem and Elevance plans. Last reviewed 2025-10-09; the published criteria edition for June will be captured the day it ships.
