Cigna modified MM 0070 for allergy testing and non-pharmacologic treatment, effective September 26, 2025. Here's what billing teams need to do.
Cigna Healthcare updated its allergy testing coverage policy under MM 0070, covering 23 CPT codes across in vivo testing, in vitro serum analysis, and allergen immunotherapy. The affected codes range from skin prick tests (CPT 95004) and intradermal tests (CPT 95024, 95027, 95028) to serum IgE panels (CPT 86003, 86005, 86008) and subcutaneous immunotherapy administration (CPT 95115, 95117, 95120, 95125, 95144, 95165). If your practice bills any allergy testing or immunotherapy for Cigna members, audit your charge capture now.

Cigna Allergy Testing Coverage Criteria and Medical Necessity Requirements 2025
The Cigna allergy testing coverage policy under MM 0070 Cigna system covers both in vivo and in vitro testing — but only when specific medical necessity criteria are met. "In vivo" means testing done on or near the patient with direct monitoring of their physiological response. "In vitro" means analyzing the patient's serum in a lab setting. Both approaches are covered, but you need the right documentation before you bill.
The real issue here is the phrase repeated across all 23 codes: "Considered Medically Necessary when criteria in the applicable Coverage Policy are met." That's Cigna telling you the criteria exist and your claims will be measured against them. Submitting CPT 86003 or 86008 for IgE quantification without documentation that ties back to those criteria is a direct path to claim denial.
For allergen immunotherapy, coverage extends to subcutaneous injection immunotherapy and sublingual antigen extract drop preparations. Codes 95115 and 95117 cover professional services for immunotherapy without the allergenic extract itself. Codes 95120 and 95125 cover professional services when the prescribing physician provides the extract in their own office. Code 95165 covers multi-dose vial preparation and supervision. Each has its own billing nuance — don't treat them interchangeably on your claim form.
Prior authorization requirements under this policy are not explicitly enumerated in the MM 0070 summary, but Cigna routinely requires prior auth for immunotherapy series and for certain in vitro panels. Check Cigna's authorization lookup tool for your specific plan type before scheduling ingestion challenge testing (CPT 95076, 95079) or bronchial challenge testing (CPT 95070). Those are the codes most likely to trigger a prior authorization review.
Reimbursement for allergy testing varies significantly by site of service and by whether the professional component is billed separately from the technical component. CPT 95199 — the unlisted allergy/immunologic service code — requires special handling. Cigna expects documentation that justifies why no existing code captures the service. Submitting 95199 without a detailed cover letter is a claim denial waiting to happen.
Cigna Allergy Testing Exclusions and Non-Covered Indications
The MM 0070 policy data does not enumerate explicit exclusions or experimental designations at the code level — every listed CPT code carries the "medically necessary when criteria are met" designation. That's not a green light across the board. It means coverage is conditional, not automatic.
The real exposure here is testing volume. Cigna scrutinizes allergy panels that appear excessive relative to the documented clinical picture. Billing 50 units of CPT 95004 (percutaneous scratch/prick tests) for a patient with a focused chief complaint of seasonal rhinitis will draw attention. Document the clinical rationale for test volume explicitly in the chart.
Sublingual antigen extract drop immunotherapy is covered under this policy, but it sits in a gray zone with many commercial payers. If you're billing sublingual preparations alongside CPT 95199 or using unlisted codes, verify that your documentation clearly distinguishes the preparation from subcutaneous immunotherapy. Conflating the two is a common billing error under MM 0070.

Cigna Allergy Testing Billing Guidelines and Action Items 2025
1. Pull every Cigna allergy claim from the last 90 days and map it to MM 0070.
Compare your current charge capture against the 23 CPT codes in this policy. If you're billing codes not on this list, investigate how those claims have been processed. If you're billing codes on this list without documented medical necessity criteria, you have a retroactive risk exposure.
2. Update your charge capture and superbill for the September 26, 2025 effective date.
Any claim with a date of service on or after September 26, 2025 must be billed under the revised MM 0070 criteria. Build a hard stop in your billing system to flag allergy claims missing a documented clinical indication.
3. Standardize documentation templates for the highest-volume codes.
CPT 95004, 95024, 86003, and 95165 are the workhorses of most allergy practices. Create templated clinical notes that capture the specific criteria Cigna requires for medical necessity. Your allergists need to see what the billing criteria look like — translate them into clinical language they'll actually use in documentation.
4. Verify prior authorization requirements before scheduling bronchial and ingestion challenge tests.
CPT 95070 (inhalation bronchial challenge) and CPT 95076/95079 (ingestion challenge tests) carry clinical complexity that flags them for utilization review. Call Cigna's provider line or check the authorization portal before the appointment date. A denied auth is far more expensive to appeal than the five minutes the check takes.
5. Handle CPT 0165U and 0178U with extra scrutiny.
These are proprietary lab codes for peanut allergen epitope quantification using ELISA. They're covered under MM 0070 when criteria are met, but they're also the kind of specialty molecular codes that get processed differently across Cigna plan types. Confirm the specific plan covers these codes before billing. If you're not sure how they apply to your payer mix, talk to your compliance officer or billing consultant before the September 26, 2025 effective date.
6. Don't bill CPT 95199 without a documentation package.
Every unlisted code submission to Cigna needs a narrative explanation of what was performed and why no existing code captures it. Attach it to the claim. If you're billing 95199 routinely, that's a separate problem — it means you may have a charge description master gap, and you should address it before it attracts a Cigna audit.
7. Check sublingual immunotherapy billing against current plan benefits.
The MM 0070 Cigna coverage policy explicitly includes sublingual antigen extract drop immunotherapy preparations. That's a positive signal. But coverage at the policy level doesn't guarantee coverage at the plan level. Verify member benefits before billing sublingual prep codes, and document the treatment modality clearly in the chart.

Key ICD-10-CM Diagnosis Codes — The MM 0070 policy data does not list specific ICD-10-CM codes. Use the diagnosis codes that document the clinical indication driving the testing — allergic rhinitis (J30.x), asthma (J45.x), food allergy (Z91.01x), contact dermatitis (L23.x-L25.x), and anaphylaxis history (Z87.39) are the most common supporting diagnoses in allergy billing. Match your ICD-10 selection to the specific test being performed and the documented clinical indication.
