TL;DR: Aetna, a CVS Health company, modified CPB 0608 — its salivary tests coverage policy — effective October 2, 2025. Billing teams should audit their charge capture for cortisol codes 82530 and 82533, confirm diagnosis coding against the covered ICD-10 list, and watch for claim denials on the large group of salivary hormone and biomarker tests that remain not covered.
CPB 0608 Aetna governs coverage for a wide range of salivary diagnostic tests across endocrinology, oncology, and hormone monitoring. The October 2 modification narrows and clarifies which tests meet medical necessity — and the list of what doesn't is long. If your practice bills salivary-based hormone panels or uses HCPCS S3650 for menopause-related saliva testing, this change directly affects your reimbursement.

Aetna Salivary Test Coverage Criteria and Medical Necessity Requirements 2025
Aetna's updated coverage policy under CPB 0608 is direct: late-night salivary cortisol testing meets medical necessity for diagnosing Cushing's syndrome. That's the covered use case. Everything else in this policy is either not covered, experimental, or investigational.
If your team bills CPT 82530 (cortisol, free) or CPT 82533 (cortisol, total) via saliva collection, you have a covered service — but only when the clinical indication is Cushing's syndrome diagnosis. That means your ICD-10 coding must map to the E24.x code range (E24.0 through E24.9).
Prior authorization requirements for salivary cortisol testing are not explicitly detailed in this policy update. Check your Aetna plan-specific requirements before submitting claims. If you're billing salivary cortisol for any indication outside Cushing's syndrome — fatigue evaluation, stress testing, functional medicine panels — expect a claim denial. Aetna does not consider those uses medically necessary under this policy.
The real issue here is scope. This policy covers 32 CPT codes and one HCPCS code, but only two of those CPT codes (82530 and 82533) sit in the "covered if selection criteria are met" group for the cortisol indication. The rest are specifically associated with salivary biomarker testing that Aetna deems not medically necessary or not covered for the listed indications.
Aetna Salivary Test Exclusions and Non-Covered Indications
This is where CPB 0608 does its most damage to revenue cycle teams. The "measurement of salivary levels of hemoglobin, matrix metalloproteinase, and other biomarkers" group contains the bulk of codes in this policy — and Aetna does not cover them.
HCPCS S3650 (saliva test, hormone level; during menopause) is explicitly not covered. If your OB/GYN or menopause clinic bills S3650 to Aetna, stop now. This has been a common claim denial trigger, and the October 2 update reinforces that position.
The salivary hormone panel codes — including CPT 82670 (estradiol), 82671 (estrogens, fractionated), 82677 (estriol), 82679 (estrone), 84144 (progesterone), 84402 (testosterone, free), and 84403 (testosterone, total) — all fall into the not-covered group under this policy. Salivary measurement of sex hormones is not an accepted alternative to serum testing in Aetna's view.
Salivary thyroid testing is also out. CPT codes 84436 (thyroxine, total), 84439 (thyroxine, free), 84443 (TSH), 84479 (thyroid hormone uptake), 84480 (T3 total), and 84481 (T3 free) — none of these are covered when billed as salivary tests under this policy. Thyroid function belongs in serum, as far as Aetna is concerned.
Other notable exclusions:
| # | Excluded Procedure |
|---|---|
| 1 | CPT 83520 (immunoassay, quantitative) — not covered for salivary interleukin-6 measurement |
| 2 | CPT 83529 (interleukin-6) — excluded as "salivary cytokinase" |
| 3 | CPT 83615 (lactate dehydrogenase) — not covered when billed as salivary LDH |
| 4 | CPT 82626 (DHEA) and 82627 (DHEA-S) — not covered via saliva |
| 5 | CPT 83937 (osteocalcin) — not covered |
| 6 | CPT 86316 (tumor antigen immunoassay) — not covered for this indication |
| 7 | CPT 0462U (melatonin levels, sleep study, 7 or 9 sample profile with optional cortisol) — not covered under this policy |
The oral cancer codes — CPT 0296U (gene expression profiling for oral/oropharyngeal cancer) and immunohistochemistry codes 88341, 88342, and 88344 — also appear in the not-covered group for salivary biomarker measurement purposes.
CPT 0011U (prescription drug monitoring via LC-MS/MS using oral fluid) is listed but falls outside the cortisol coverage criteria. If your lab bills 0011U to Aetna as a salivary test under CPB 0608 indications, verify coverage status before October 2, 2025.

Aetna Salivary Test Billing Guidelines and Action Items 2025
| # | Action Item |
|---|---|
| 1 | Audit your charge capture for CPT 82530 and 82533 before October 2, 2025. These are the only two CPT codes with a covered pathway under CPB 0608. Confirm that every claim for these codes pairs with a Cushing's syndrome diagnosis (E24.x). Any other indication will likely result in a claim denial. |
| 2 | Stop billing HCPCS S3650 to Aetna. This code is explicitly not covered under CPB 0608. If your menopause clinic or OB/GYN practice has been using S3650 for salivary hormone testing, pull your last 90 days of Aetna claims and identify any that may be subject to recoupment. |
| 3 | Remove salivary hormone panels from your Aetna fee schedule workflows. CPT codes 82670, 82671, 82672, 82677, 82679, 84144, 84402, and 84403 billed as salivary tests will not be reimbursed. If your lab offers these panels, add Aetna as a payer exclusion in your billing system for these codes in the salivary context. |
| 4 | Flag CPT 0462U in your lab billing system. The melatonin/sleep study salivary panel (0462U) is not covered. If your sleep medicine program uses salivary melatonin profiling and bills 0462U to Aetna members, expect denials. Review those cases now. |
| 5 | Review CPT 0011U oral fluid drug monitoring claims. This code appears in the CPB 0608 code set. Aetna's coverage position on oral fluid drug testing can vary by plan. Contact your Aetna provider relations rep or check plan-specific billing guidelines before the October 2 effective date. |
| 6 | Confirm ICD-10 documentation for all covered cortisol claims. Your physician documentation must support a Cushing's syndrome workup. A diagnosis of fatigue, weight gain, or general adrenal dysfunction without documented suspicion of Cushing's syndrome will not support medical necessity. Brief your clinical documentation improvement team now. |
| 7 | If your practice runs a functional medicine or integrative health panel that includes salivary hormones for Aetna patients, talk to your compliance officer. These panels routinely include multiple codes listed as not covered under CPB 0608. Billing them to Aetna — even as part of a broader panel — creates claim denial and potential overpayment risk. |
