Human Chorionic Gonadotropin (hCG) (CPB 1081, reviewed 12-2025-08)
Aetna updated its hCG (Human Chorionic Gonadotropin) clinical policy (CPB 1081) effective December 2025. Key coverage remains for ART/ovulation induction, cryptorchidism, hypogonadotropic hypogonadism, and acute GVHD, but the policy explicitly excludes coverage for hCG used solely for endometrium preparation in frozen embryo transfer (FET). Precertification is required for all hCG products (Novarel, Pregnyl, Ovidrel, generics), and specialty pharmacy medical necessity review may be bypassed if the underlying infertility procedure is pre-approved.

Bone Mineral Density Studies
Bone density measurements are covered once per lifetime for general osteoporosis screening for women beginning at age 65 under the Healthy You! Wellness benefit, and screening is limited to the hips or spine using DEXA. An initial hip or spine measurement may be considered medically necessary for women age 65 and older, men age 70 and older, and others at risk of osteoporosis, and repeat measurements may be considered not more often than every 5 years for at-risk individuals who previously tested normal. The 10/01/2026 update added ICD-10 codes K74.0A, K76.83, Z68.18 and Z68.19, and Z68.1 was deleted as of 09/30/2026.

Use for endometrium preparation alone for frozen embryo transfer, idiopathic male infertility, idiopathic microphallus and obesity or weight loss is considered experimental, investigational or unproven.

Aetna considers open or laparoscopic fundoplication, or Roux-en-Y gastric bypass for members who meet CPB 0157 criteria, medically necessary when reflux is documented by abnormal 24-hour pH monitoring or endoscopically proven esophagitis and one of the listed criteria is met. The listed criteria include moderate-to-severe GERD incompletely controlled by at least 1 month of twice-daily proton pump inhibitor therapy and lifestyle modifications, a large hiatal hernia (more than 2 cm in diameter, measured endoscopically), high-volume reflux, and respiratory symptoms with typical reflux symptoms and positive esophageal pH testing. Many endoscopic and device treatments are listed as experimental, investigational, or unproven for GERD, including Stretta, EsophyX or StomaphyX, Enteryx, Gatekeeper, Durasphere, EndoStim, and the LINX Reflux Management System (see CPB 0157 for GERD related to bariatric complications).
