This bill amends Chapter 18, Title 41 of the Idaho Code by adding a new section, 41-1854, which establishes provisions for coverage of certain fertility preservation services. The bill defines "fertility preservation services" to include the collection and preservation of sperm, unfertilized oocytes, and ovarian tissue, but explicitly excludes the storage of these genetic materials. It applies to various health benefit plans, including individual and group insurance policies, and mandates that these plans provide coverage for fertility preservation services for individuals undergoing medically necessary treatments for cancer that may impair fertility, as recognized by the American Society of Clinical Oncology and the American Society for Reproductive Medicine.

Additionally, the bill specifies that the fertility preservation services covered must align with established medical practices or professional guidelines. An emergency clause is included, declaring that the act will take effect on July 1, 2026.
