TL;DR: Aetna, a CVS Health company, modified CPB 0107 governing chiropractic services coverage, effective September 26, 2025. Here's what billing teams need to do before claims start hitting the wall.
Aetna's chiropractic services coverage policy under CPB 0107 sets strict, time-boxed medical necessity gates for CPT codes 98940, 98941, 98942, and 98943 — the four core chiropractic manipulative treatment codes your team bills every week. The policy ties reimbursement directly to documented improvement, with hard 14-day and 30-day checkpoints that determine whether continued care is covered at all. If your documentation workflow isn't built around those timelines, expect claim denial.

Aetna Chiropractic Services Coverage Criteria and Medical Necessity Requirements 2025
Aetna's chiropractic billing guidelines under CPB 0107 are built on three concurrent requirements. Every single one must be met for a claim to be considered medically necessary.
First, the member must have a neuromusculoskeletal disorder. Second, medical necessity must be clearly documented in the chart. Third — and this is where most claims fall apart — improvement must be documented within the initial two weeks of care.
That two-week window is not a soft guideline. Aetna treats it as a hard cutoff. If your chiropractor's notes don't show measurable improvement by day 14, Aetna considers additional treatment not medically necessary. Full stop.
There's a modification pathway, but it's narrow. If treatment is modified after the two-week mark, the clock resets — but only to 30 days. If no improvement shows after 30 days despite the modified approach, Aetna considers continued care not medically necessary under this coverage policy. There is no third reset.
The policy also draws a clear line on plateau cases. Once maximum therapeutic benefit has been achieved, ongoing maintenance care is not covered. This is the "static patient" provision that catches a lot of long-term chiropractic patients. If the condition is neither regressing nor improving, the patient has plateaued — and Aetna won't pay for continued manipulation.
This coverage policy does not mention prior authorization requirements explicitly within the medical necessity criteria, but given the documentation-intensity of these standards, your billing team should confirm prior auth requirements at the plan level before submitting claims for extended treatment courses. Contact your Aetna provider relations rep if you're unsure which commercial or Medicare Advantage products attached to CPB 0107 require prior auth.
Reimbursement for CPT 98940 through 98943 depends entirely on this documentation chain. No documented improvement equals no covered reimbursement — Aetna's policy makes that direct connection.
Aetna Chiropractic Services Exclusions and Non-Covered Indications
Several categories are explicitly excluded from coverage under CPB 0107. These are worth knowing cold, because they show up in charts more often than you'd think.
Asymptomatic patients. Chiropractic manipulation in persons without symptoms or without an identifiable clinical condition is not medically necessary. If a patient presents for "preventive" or wellness-based adjustments, that claim won't pass Aetna's medical necessity review.
Idiopathic scoliosis — with conditions. Chiropractic manipulation has no proven value for idiopathic scoliosis or for scoliosis beyond early adolescence, per this policy. There is a narrow exception: if the member shows pain, muscle spasm, or another medically necessary indication for manipulation, coverage may apply. Document that indication explicitly. Don't assume it carries over from a prior visit note.
Plateau cases. Any patient whose condition is neither regressing nor improving falls outside covered care. This is separate from the two-week improvement window — it applies to ongoing care at any stage. If a long-term chiropractic patient has stopped showing objective improvement, continued billing creates real claim denial risk.
Maintenance care. Once maximum therapeutic benefit is reached, continuing care is not covered. This is where many chiropractic practices quietly accumulate denials. If your team bills Aetna for long-term chiropractic patients who've stabilized, review those cases now.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Neuromusculoskeletal disorder with documented improvement at 2 weeks | Covered | 98940, 98941, 98942, 98943 | All three criteria must be met simultaneously |
| Continued care after 2-week improvement check with modified treatment | Covered (conditionally) | 98940, 98941, 98942, 98943 | Improvement must be documented by day 30 or coverage ends |
| Home-based chiropractic care for homebound members | Covered (selected cases) | G0151, S9131 | Member must be homebound; may apply during hospital-to-home transition |
| Chiropractic care in asymptomatic patients | Not Covered | 98940–98943 | No identifiable clinical condition = not medically necessary |
| Care for patients at maximum therapeutic benefit (maintenance) | Not Covered | 98940–98943 | Plateau = no coverage under CPB 0107 |
| Care where condition is neither improving nor regressing | Not Covered | 98940–98943 | Applies at any stage of care |
| Chiropractic manipulation for idiopathic scoliosis (without symptoms) | Not Covered | 98940–98943 | Exception exists if pain, spasm, or other medically necessary indication is documented |
| Chiropractic manipulation for scoliosis beyond early adolescence (without symptoms) | Not Covered | 98940–98943 | Same exception applies — document the indication explicitly |
| Spinal manipulation under anesthesia | Conditional | 22505 | Grouped with ConnecTX and inertial traction protocols; review plan-level coverage |
Aetna Chiropractic Billing Guidelines and Action Items 2025
The effective date is September 26, 2025. These action items apply now.
| # | Action Item |
|---|---|
| 1 | Audit your documentation templates before September 26, 2025. Your SOAP notes or progress notes for chiropractic visits must capture measurable improvement at or before the two-week mark. "Patient reports feeling better" doesn't cut it. Use objective measures — pain scales, range of motion, functional improvement scores — and make sure they appear in the chart by visit four or five. |
| 2 | Flag all active Aetna chiropractic patients receiving ongoing care. Run a report on patients with 12 or more Aetna-billed chiropractic visits in the past 90 days. For each, confirm the chart shows a documented improvement trajectory — not a plateau. If a patient has stabilized, that case needs a clinical review before the next billing cycle. |
| 3 | Build a 14-day checkpoint alert into your scheduling or EHR workflow. The two-week improvement gate isn't optional, and it's easy to miss in a busy practice. Set an automated flag at visit three or four so the treating chiropractor knows a documented improvement note is required before the next claim goes out. |
| 4 | Update your treatment modification workflow. If a patient doesn't show improvement at two weeks, the policy allows a path forward — but only if the treatment approach is modified and documented as changed. "Modified treatment" needs to be explicit in the chart. Note what was changed and why. Then track from that point to day 30. |
| 5 | Review home-based chiropractic claims separately. CPB 0107 covers home-based chiropractic services in selected cases where the member is genuinely homebound. If your practice bills G0151 or S9131 in connection with home chiropractic care, confirm homebound status is documented and that the service connects to a hospital-to-home transition or case management plan. These claims get scrutinized. |
| 6 | Don't bill for plateau patients. If your clinical notes show the patient has reached maximum therapeutic benefit or is holding steady without change, stop billing Aetna for additional manipulation. Those claims will deny, and repeated submissions create audit exposure. Have the treating chiropractor document the plateau formally and close the active treatment episode. |
| 7 | Check prior auth requirements at the plan level. CPB 0107 doesn't spell out prior authorization triggers uniformly across all Aetna products. Your Aetna commercial, Medicare Advantage, and Medicaid managed care contracts may each handle prior auth differently for extended chiropractic courses. Check the specific plan before submitting claims beyond visit six or eight. |
