TL;DR: Aetna, a CVS Health company, modified CPB 0628 governing spinal ultrasound coverage, effective December 12, 2025. CPT 76800 is the only covered code under this policy, and the covered indications are narrow. Here's what billing teams need to know.
Aetna's spinal ultrasound coverage policy under CPB 0628 draws a hard line: CPT 76800 (ultrasound, spinal canal and contents) is covered for a short list of pediatric and intraoperative indications only. Every other use—including ultrasound-guided epidural blocks, spinal muscular atrophy management, and lumbar puncture guidance in adults—is classified as experimental, investigational, or unproven. If your team bills spinal ultrasound for pain management, anesthesia guidance, or musculoskeletal evaluation in adult patients, this policy will generate claim denials.

Aetna Spinal Ultrasound Coverage Criteria and Medical Necessity Requirements 2025
Aetna's spinal ultrasound coverage policy is one of the most restrictive you'll encounter for imaging. Medical necessity under CPB 0628 applies to CPT 76800 in exactly two clinical contexts: pediatric cases meeting specific indications, and intraoperative use.
For newborns and infants, Aetna considers spinal ultrasound medically necessary for seven defined indications. These include detection of injury sequelae (hematoma after spinal tap or birth injury, post-traumatic cerebrospinal fluid leakage, and sequelae of prior instrumentation, infection, or hemorrhage), evaluation of suspected defects such as cord tethering, diastematomyelia, hydromyelia, and syringomyelia, and guidance for lumbar puncture. The policy also covers lumbosacral stigmata associated with spinal dysraphism, post-operative assessment for cord retethering, caudal regression syndrome spectrum (including anal atresia or stenosis and sacral agenesis), and visualization of blood-product-characteristic fluid within the spinal canal in neonates and infants with intracranial hemorrhage.
Intraoperative use is the second covered category. When CPT 76800 is performed during surgery, it meets medical necessity under this policy.
Outside those two buckets, the answer is no. Aetna does not treat spinal ultrasound as a covered service for adult diagnostic work, pain management procedures, or anesthesia guidance. If you are billing CPT 76800 alongside epidural injection codes (62320–62327) or nerve block codes (64400–64470 series) expecting reimbursement for ultrasound guidance, this coverage policy says those claims will not pass.
The policy does not list specific prior authorization requirements for CPT 76800, but the narrow covered indications mean documentation must be airtight. Any claim for CPT 76800 without clear documentation of neonatal/infant age or intraoperative context is a denial waiting to happen.
Aetna Spinal Ultrasound Exclusions and Non-Covered Indications
This is where CPB 0628 does the most damage to billing teams—especially those supporting pain management and anesthesia practices.
Aetna explicitly classifies spinal and para-spinal tissue ultrasound as experimental, investigational, or unproven for any use not listed in the covered indications. The policy names three specific exclusion categories.
First: diagnostic ultrasound of the spine and para-spinal tissues for evaluation of neuro-musculoskeletal conditions. This sweeps in a wide range of common adult applications—evaluating curve flexibility before surgical intervention for scoliosis, evaluating and managing spinal epidural abscess, and assisting in lumbar puncture (except in newborns and infants). It also covers all neuraxial block guidance, meaning ultrasound used to assist epidural and subarachnoid procedures is not covered.
Second: management of individuals with spinal muscular atrophy. If your practice treats SMA patients and uses ultrasound as part of that management, do not bill CPT 76800 to Aetna expecting payment.
Third: SonixGPS. This real-time ultrasound-guided spinal anesthesia system is called out by name as experimental. If your anesthesia team uses it, there is no coverage pathway under this policy.
The real issue here is the neuraxial block exclusion. Ultrasound guidance for epidural and subarachnoid blocks has become standard practice in many anesthesia settings. Aetna's position is that the evidence base does not support coverage. That puts you in a tough spot if your group has built a workflow around CPT 76800 billing alongside the 62320–62327 injection series.

Aetna Spinal Ultrasound Billing Guidelines and Action Items 2025
The effective date of December 12, 2025 is already here. These are the steps your billing team needs to take now.
| # | Action Item |
|---|---|
| 1 | Audit all CPT 76800 claims billed to Aetna. Pull claims from the past 12 months. Flag any that were billed alongside epidural injection codes (62320–62327), nerve block codes (64400 series), or with adult patients. Identify your denial rate and assess whether incorrect billing has been systematic. |
| 2 | Update your charge capture to require age and indication documentation for CPT 76800. Your charge capture system should flag CPT 76800 at the point of order entry and require the clinician to confirm the patient is a newborn or infant, OR that the procedure is intraoperative. No documentation, no billing. |
| 3 | Remove CPT 76800 from standard anesthesia and pain management charge templates. If your anesthesia or pain management groups have CPT 76800 bundled into their default procedure templates for epidural or nerve block cases, pull it out now. Leaving it in place generates automatic denials and potential overpayment exposure. |
| 4 | Educate your anesthesia and pain management teams on the SonixGPS exclusion. The named-device exclusion for SonixGPS is specific. If your anesthesiologists use this system, they need to know there is no billing pathway for it under Aetna plans. This is not a gray area—the policy names the device. |
| 5 | Review documentation practices for covered pediatric indications. Claims for covered neonatal and infant cases will still deny if the documentation doesn't support the specific listed indication. Train your pediatric neurology, neonatology, and pediatric surgery teams to document the exact indication—"cord tethering evaluation," "post-spinal tap hematoma," "caudal regression syndrome with sacral agenesis"—not just "spinal ultrasound." |
| 6 | Check your SMA patient population. If you treat spinal muscular atrophy patients under Aetna plans and have been billing CPT 76800 for monitoring or management, stop. The policy is explicit. If you have outstanding claims, assess your exposure and talk to your compliance officer before the end of year. |
If your practice has high volume in pain management or anesthesia with Aetna-insured patients, the financial exposure here is real. Loop in your compliance officer and billing consultant to assess retrospective claim risk before December 31, 2025.
