CPT® Code 82166

The Anti-Mullerian Hormone (AMH) test, identified by CPT® Code 82166, is a laboratory procedure that quantifies the concentration of AMH in the bloodstream. This hormone is produced by the ovarian follicles, which are the fluid-filled sacs that contain and release eggs. The measurement of AMH levels is particularly significant in the context of reproductive health, as it provides insights into a woman's ovarian reserve, which refers to the number of viable eggs remaining in the ovaries. While AMH levels can indicate the quantity of eggs, it is important to note that they do not serve as a direct predictor of fertility. As women age, AMH levels typically decline, with higher concentrations observed in younger women, particularly around the age of 25, compared to those in their mid to late 30s and beyond. This decline in AMH is a natural part of the aging process and can influence a woman's reproductive timeline. Clinicians often utilize AMH testing to assist in planning infertility treatments, as the results can inform decisions regarding the use of injectable fertility medications and the stimulation of the ovaries to enhance egg production. Additionally, AMH levels have diagnostic implications beyond fertility. They can be instrumental in identifying certain ovarian conditions, such as granulosa cell tumors, and in monitoring the effectiveness of treatment for these tumors. Furthermore, elevated AMH levels may be associated with polycystic ovarian syndrome (PCOS), a common endocrine disorder that can affect a woman's menstrual cycle and fertility. Overall, the AMH test is a valuable tool in both fertility assessment and the management of specific ovarian health issues.
