Reflex Sympathetic Dystrophy Diagnosis — CPB 0147 | AETNA Coverage Update

TL;DR: Aetna, a CVS Health company, modified CPB 0147 — its coverage policy for complex regional pain syndrome (CRPS) diagnosis, formerly called reflex sympathetic dystrophy (RSD) — effective September 26, 2025. Here's what billing teams need to do before claims hit the wall.

This update to the Aetna CRPS coverage policy touches a broad range of diagnostic imaging codes, including radiologic examinations of the upper extremities (CPT 73000–73077 range) and pelvis (CPT 72170, 72190). The policy governs how Aetna evaluates medical necessity for CRPS diagnostic workups. If your practice bills for pain management, neurology, or musculoskeletal imaging in Aetna-covered populations, this change is on your radar as of September 26, 2025.

Aetna CRPS Diagnosis Coverage Criteria and Medical Necessity Requirements 2025

CPB 0147 in the Aetna system governs coverage for diagnosing complex regional pain syndrome — a condition that used to be documented under the older "reflex sympathetic dystrophy" terminology. That name change matters for your ICD-10 coding and documentation. If your providers still use RSD in clinical notes, your coders need to map that to the correct CRPS diagnosis codes before billing.

The Aetna CRPS coverage policy centers on clinical diagnosis. CRPS is a clinical diagnosis — not one made primarily through imaging. That creates a tension with the large number of radiologic CPT codes referenced in this policy. The imaging codes listed (including the CPT 73000 series for upper extremity radiology and CPT 72170 and 72190 for pelvis) appear in the policy's code list, but they are not standalone proof of medical necessity. Your documentation must show the clinical picture first.

Medical necessity for CRPS diagnostic workups under this Aetna coverage policy requires that imaging and other diagnostic studies be ordered as part of a clinical evaluation — not as a fishing expedition. Aetna expects the record to support CRPS suspicion before imaging is authorized. If you're billing for these studies without documentation of the clinical presentation (allodynia, vasomotor changes, trophic changes, or motor dysfunction), expect a claim denial.

Prior authorization requirements for diagnostic imaging in CRPS workups vary by plan. Check the specific member's benefit plan before scheduling advanced imaging. Aetna's commercial plans often require prior auth for certain radiology services, and CRPS cases are not exempt. Don't assume clinical urgency overrides the prior authorization requirement.

Aetna CRPS Diagnosis Billing Guidelines and Action Items 2025

The policy modification date is September 26, 2025. That's your line in the sand. Claims for dates of service on or after that date fall under the updated policy. Here's what to do now.

1. Audit your CRPS-related charge capture for radiology codes.
Pull claims from the past 90 days where you billed CPT codes in the 73000–73077 range or CPT 72170 and 72190 with a CRPS or RSD diagnosis. Compare your documentation against what CPB 0147 requires. If your notes don't show a clinical basis for the imaging, you have exposure.

2. Update any order sets or charge capture templates that still reference "reflex sympathetic dystrophy."
The condition is CRPS now. Your ICD-10 codes, clinical templates, and referral language should reflect that. Aetna's policy uses the current terminology, and coding to outdated terms creates reconciliation problems.

3. Verify prior authorization requirements for imaging on a plan-by-plan basis.
Don't assume all Aetna plans handle CRPS imaging the same way. HMO, PPO, and EPO products within Aetna can have different prior auth thresholds. Check the member's specific plan before scheduling radiology for CRPS workups.

4. Train your documentation team on the medical necessity standard.
Reimbursement for these diagnostic codes depends on the clinical record showing CRPS suspicion — not just an order for imaging. Your physicians need to document the signs and symptoms that justify each study. One-line orders ("rule out CRPS") will not cut it.

5. Watch for claim denials citing CPB 0147 and respond quickly.
If you get a denial citing this policy, pull the clinical notes before you appeal. If the documentation supports medical necessity, appeal with the record. If it doesn't, that's a documentation process problem — fix it upstream. Denials on CRPS imaging claims tend to cluster when providers order broad imaging panels without supporting clinical detail.

6. Loop in your compliance officer if you're unsure how this applies to your patient mix.
If your practice sees high CRPS volume or uses standing imaging protocols for RSD/CRPS workups, talk to your compliance officer before the effective date of September 26, 2025 passes without a review. This is one of those policies where the code list looks broad but the coverage standards are narrow.

CPT, HCPCS, and ICD-10 Codes for CRPS Diagnosis Under CPB 0147

The code set in this policy is large — 345 CPT codes total, plus ICD-10 diagnosis codes. The policy data provided includes a representative sample of the CPT codes and confirms the full list runs to 345 entries. Below is what the data directly supports.

Covered CPT Codes (When Medical Necessity Criteria Are Met)

These codes appear in CPB 0147. Coverage is conditional on documented medical necessity for CRPS diagnostic evaluation.

Note: The policy data provided includes 345 total CPT codes. The full code list — including the 265 codes beyond what's shown above — is available in the complete CPB 0147 policy document. Access the full policy on PayerPolicy.

Key ICD-10-CM Diagnosis Codes

The policy lists three ICD-10-CM codes. The policy data provided confirms their presence but does not include the specific code values and descriptions in the excerpt above. Pull the complete CPB 0147 document to confirm the exact ICD-10 codes before updating your charge capture.

Action: Access the full CPB 0147 policy at app.payerpolicy.org/p/aetna/0147 to confirm all three ICD-10-CM codes and apply them to your CRPS billing workflows.

A Note on the Code Data Quality in CPB 0147

This is worth flagging directly. The "Group" column in the policy data for these CPT codes references "CREB-binding protein (CREBBP), Measurement of serum anti-neu" — which has nothing to do with musculoskeletal radiology or CRPS diagnosis. That looks like a data tagging error in the source document, not a clinical criteria description.

Don't let that group label confuse your billing team. The codes themselves (upper extremity and pelvis radiology) are consistent with CRPS diagnostic workups. The group label appears to be a system artifact. When you access the full CPB 0147 policy, verify how Aetna has grouped and categorized these codes in the actual policy text — not just in the metadata.

This kind of discrepancy is exactly where claim denials originate. A coder sees a confusing code group label, applies it incorrectly, and the claim gets flagged. If something in the policy data doesn't match the clinical context, escalate to your billing consultant before assuming the data is correct.
