The ACA requires that all new ACA-compliant plans, including those in the employer market, individual market, and health insurance Marketplaces, cover lactation counseling and breast pump rental without any charge. Check your plan details to find out the specific number of counseling sessions and types of breast pump that are covered, or if your plan covers purchase of a breast pump. If you are nursing and work for a large employer (50 or more employees), your employer must provide access to a private room (that is not a bathroom) and break time for you to express milk.
Short-term health insurance policies do not have to provide benefits required by the ACA, including breastfeeding services. Health care sharing ministries, which are membership groups usually affiliated with a religion that help members pay for health care (not insurance), are also not subject to ACA benefit requirements, including breastfeeding services.
