Cigna''s Medical Necessity Rules

Verify Medical Necessity

Don't risk a denial. See if your ICD-10 code is on the approved Medicare LCD list.

Under Cigna''s official medical coverage policy, CPT 82306 is ONLY considered medically necessary when the patient has a documented underlying disease or condition specifically associated with Vitamin D deficiency.

You cannot bill 82306 to Cigna simply because a patient complains of fatigue or requests a "general wellness check."

Covered ICD-10 Conditions

To get paid by Cigna, the claim must include an ICD-10 diagnosis code that proves medical necessity. Common approved categories include:

  • Chronic Kidney Disease (CKD) stages 3, 4, or 5
  • Osteoporosis or Osteomalacia
  • Malabsorption syndromes (e.g., Crohn''s, Celiac)
  • Hypocalcemia or Hypercalcemia
  • Patients on long-term anticonvulsant or glucocorticoid therapy

NCCI Edits

Ensure you are not billing CPT 82306 on the same day as CPT 82652 (Vitamin D; 1, 25 dihydroxy) without proper Modifier 59 documentation, as they will hit a mutually exclusive NCCI edit.
