Nucleic Acid Pathogen Testing - (0530) — MM 0530 | CIGNA Coverage Update

Cigna modified MM 0530 — its nucleic acid pathogen testing coverage policy — effective February 14, 2026. If your team bills any of the 72 CPT codes under this policy, your documentation and medical necessity criteria need to be current now.

This update from Cigna Healthcare covers nucleic acid infectious pathogen testing across a wide range of clinical settings: STD testing, respiratory infections, gastrointestinal pathogens, CNS infections, wound infections, vaginal infections, and more. The MM 0530 Cigna system covers codes ranging from CPT 87490 for Chlamydia trachomatis to CPT 0480U for metagenomic CSF testing — 72 codes in total, with 453 ICD-10-CM diagnosis codes attached. Panel testing is explicitly addressed. Inpatient testing and COVID-19 solo testing are not.

Quick-Reference Table

Cigna Nucleic Acid Pathogen Testing Coverage Criteria and Medical Necessity Requirements 2026

The core rule under this Cigna coverage policy is straightforward: all 72 CPT codes are considered medically necessary when criteria in the applicable coverage position are met. That phrase does a lot of work. It means the test alone doesn't justify coverage — the clinical context does.

Cigna's medical necessity standard under MM 0530 requires that the test be ordered for a specific clinical indication, tied to a documented infection or a reasonable suspicion of one. The 453 ICD-10-CM codes attached to this policy define the universe of covered indications. If your diagnosis code isn't in that list, your claim is at risk.

Panel testing — where a single test looks for multiple pathogens at once — is explicitly addressed in this policy. Cigna covers panel testing under the same medical necessity framework. But billing a panel when a single-pathogen test was clinically appropriate is exactly the kind of pattern that triggers audits. Document why the panel was necessary, not just what it found.

The policy specifically excludes two categories from its scope. First, nucleic acid testing for SARS-CoV-2 alone falls under Cigna coverage policy 0557 — not MM 0530. If your lab bills CPT 87636 or 87637 as part of a combo panel (flu/RSV/COVID), MM 0530 applies. If it's a solo COVID test, route that to policy 0557. Second, inpatient testing is not covered under this policy at all.

Prior authorization requirements are not explicitly called out in the policy summary, but given the breadth of codes — including several high-cost PLA codes like 0152U, 0323U, and 0480U — check your Cigna contract and the provider portal before assuming PA is waived. For PLA codes specifically, reimbursement rates vary significantly, and some plans require pre-service review.

Cigna Nucleic Acid Pathogen Testing Exclusions and Non-Covered Indications

Two hard exclusions apply under MM 0530.

Inpatient testing is outside this policy's scope entirely. If your team bills nucleic acid pathogen testing for patients at an inpatient level of care, a different policy applies. Confirm with your Cigna provider relations contact which policy governs inpatient molecular testing for your facility type.

Standalone COVID-19 nucleic acid testing is excluded. CPT 87636 (SARS-CoV-2/influenza A and B) and 87637 (SARS-CoV-2/influenza A and B/RSV) are covered under MM 0530 because they test multiple pathogens. But if your lab offers a test that only detects SARS-CoV-2, that claim belongs under policy 0557, not here. Billing it under MM 0530 will likely result in a claim denial.

Cigna Nucleic Acid Pathogen Testing Billing Guidelines and Action Items 2026

If your lab bills high volumes of nucleic acid panels to Cigna — particularly GI panels, respiratory panels, or wound infection panels — loop in your compliance officer before the effective date. The combination of 72 CPT codes, 453 ICD-10 codes, and multiple PLA codes creates real audit exposure if your documentation or coding isn't tight.
