Aetna vs. Cigna vs. BCBS: Mental Health Billing Differences in 2026
A therapist billing the same 60-minute session to three different payers can see three very different checks.
Aetna pays a median of $156. Cigna pays just $120 for the exact same code, according to a dashboard built by Allia Health using public Transparency in Coverage files. BCBS is harder to pin to a single number because each state's Blue plan negotiates its own rates independently, in-network pay for that same session commonly ranges from $100 to $220, per billing-data compiled by Claim Max RCM and MedSol RCM.
Same session, same code and depending on which of the three you bill, the gap can run well past $36.
If your practice bills all three of these payers the same way, you are probably leaving money on the table or, worse, watching claims bounce back.
| Aetna | Cigna | BCBS | |
| CPT 90837 (60-min session) | ~$140–$200, generally 110–145% of Medicare | ~$120–$160, tends to run tighter than Aetna | ~$130–$220; high-cost state plans (IL, NJ, MA) commonly reach $180–$210 |
| CPT 90791 (diagnostic evaluation) | ~$200–$250 | Tends to sit closer to the Medicare baseline | Varies widely since each state Blue plan sets its own rate |
| Telehealth parity | Yes, virtual pays the same as in-person | Yes | Yes, but POS code and modifier rules differ by state plan |
| Prior auth / review triggers | Concurrent review often kicks in around session 20; heavy 90837 use flags chart audits | Frequency limits and prior auth on some plans | Set independently by each state's Blue plan, no national standard |
| Rate consistency | One national contract, but high denial scrutiny | Lower and tighter across most markets | Most variable payer, since BCBS is a network of separate state plans |
What Makes Mental Health Billing Differences Insurers Apply So Costly?
- Aetna, Cigna, and Blue Cross Blue Shield don't run on one shared rulebook.
- Each payer sets its own telehealth policies, modifier expectations, and documentation standards.
- A claim that clears with Aetna one week can get denied by BCBS the next, even with identical clinical notes.
- This usually isn't careless billing. It happens because providers assume payer rules are interchangeable when in reality, that's not the case.
- Practices with strong denial management typically monitor payer-specific billing requirements and denial trends rather than relying on a one-size-fits-all billing workflow, helping them identify recurring issues before they affect reimbursement.
Why Do Reimbursement Rates Vary So Much by Payer?
- Rate structures differ by license type, region, and contract tier, but the pattern holds across sources.
- For CPT 90837, BCBS plans commonly pay $180 to $210.
- Commercial payers overall reimburse 130% to 210% of the Medicare rate for the initial diagnostic evaluation code 90791.
- For a 45-minute session, median rates across Aetna, Cigna, and UnitedHealthcare settle around $96
- A 60-minute session averages $138 across those same three payers.
- These numbers shift again depending on whether the provider holds a PhD, PsyD, or master's-level license.
How Do Telehealth and Documentation Rules Differ Between Payers?
- Most major commercial payers have settled into permanent telehealth parity for behavioral health codes, a virtual session pays the same as an in-person one.
- But place-of-service codes and modifiers still differ by payer, and mismatches here are one of the most common reasons claims bounce back.
- Retrospective audits are increasing. Cigna, Aetna, and UnitedHealthcare have all stepped up post-payment reviews of behavioral health claims.
- When progress notes fail to show medical necessity or measurable treatment goals, practices can face clawback demands covering 12 to 24 months of paid claims.
How Can Practices Reduce Denials Across Multiple Payers?
- Build a payer-specific reference sheet instead of one universal billing checklist.
- Include telehealth POS codes, required modifiers, and documentation triggers for each insurer separately.
- Review the sheet every time a payer updates its policy, since updates rarely come with much notice.
- Set up a dedicated denial management process. Behavioral health needs this more than most specialties, since the same error can trigger different denial codes from different payers.
- Pair accurate coding with strong medical billing workflows to catch mismatches before submission, not after a rejection.
What Should a Clean Behavioral Health Claim Include?
- The correct CPT code for session length, matched to actual documented time.
- A specific ICD-10 diagnosis code rather than an unspecified one.
- Clinical notes that show measurable progress toward treatment goals.
- The payer's required telehealth modifier and place-of-service code, when applicable.
Frequently Asked Questions
Does Medicare pay more or less than commercial insurers for therapy sessions?
Commercial payers generally reimburse well above Medicare for behavioral health codes. Medicare's 2026 rate for CPT 90837 is $167, while commercial rates for the same code often exceed 130 percent of that figure.
Why did my BCBS claim deny when the same code worked with Aetna?
The most common cause is a mismatched modifier or place-of-service code. Each payer applies its own telehealth and documentation rules, so a setup that works for one insurer will not automatically work for another.
Do all Blue Cross Blue Shield plans pay the same rate?
No. BCBS is a network of independent, state-run plans, so rates and policies can vary significantly from one state's Blue Cross plan to another.
How often should billing teams update their payer rules reference?
Review it quarterly at minimum, and immediately after any payer sends a policy notice, since telehealth and modifier rules change often in behavioral health.
