Additional Information

Estradiol is the primary estrogen hormone responsible for the development and regulation of the female reproductive system and secondary sexual characteristics. It plays a critical role in the menstrual cycle, fertility, bone density maintenance, and cardiovascular health. Estradiol levels fluctuate throughout the menstrual cycle and decline significantly during menopause. Clinically, estradiol measurement is used to evaluate ovarian reserve, monitor ovulation induction therapies, diagnose disorders such as polycystic ovary syndrome (PCOS) and hypogonadism, and assess estrogen-producing tumors.

Footnotes

Statement on Medical Necessity
All ordered tests should be medically necessary for the diagnosis or detection of disease, illness, impairment, symptom, syndrome, or disorder and the results should be used in the medical management and treatment decisions for the patient. Solaris requires ICD-10 codes with each order for lab testing and both the tests ordered and the diagnosis should be documented in the provider’s medical record for the patient. The United States Department of Health and Human Services, Office of Inspector General, takes the position that a provider who orders medically unnecessary tests may be subject to civil penalties.

Panels and Profiles
Solaris offers Providers the convenience of ordering test combinations in a group at times with the flexibility to choose appropriate test(s) for individual patients. Providers should only order those tests that he or she believes are medically necessary for each patient, and a lesser inclusive profile or individual tests should be ordered if not all tests in the test combination/profile are medically necessary. All tests offered in a test combination/profile may be ordered separately as individual tests. Solaris encourages clients to contact their Solaris representative if the testing configurations shown do not meet individual needs for any reason, or if some other combination of procedures is needed.

CPT Codes
CPT Codes listed are in accordance with Current Procedural Terminology, a publication of the American Medical Association. CPT codes are the responsibility of the billing party and are listed here for informational purposes. Correct coding may vary from one carrier to another.
