Summary
Medicare Advantage has revised its genetic testing policy to cover DNA analysis for diagnosing inherited conditions in symptomatic patients. The policy permits genetic testing to confirm diagnoses and guide treatment decisions for conditions including achondroplasia, alpha-1 antitrypsin deficiency, Barth syndrome, cardiofaciocutaneous syndrome, celiac disease, Charcot-Marie-Tooth disease, and epidermolysis bullosa, among others.
Action Required
URGENT: Billing team must obtain the complete policy document from the Humana DCTM portal (https://dctm.humana.com/Mentor/Web/v.aspx?objectID=090009298a57f0ed) immediately, as the provided summary is incomplete (text ends mid-sentence). Once full policy is retrieved: (1) Identify all specific CPT codes for genetic testing covered under this revision; (2) Determine prior authorization requirements and any medical necessity documentation needed; (3) Update billing system rules and encounter forms to reflect new coverage parameters; (4) Brief clinical staff on which inherited conditions now qualify for covered genetic testing; (5) Establish internal guidelines for medical record documentation requirements. Do NOT bill genetic testing claims under this revised policy until the complete policy details are reviewed and billing system updates are completed. Contact Humana provider relations for effective date and implementation timeline.
