CPT 82166 · AMH + Day 2–4 Hormones
82166 is AMH, the ovarian reserve test. FSH (83001), LH (83002) and estradiol (82670) are drawn on cycle day 2 to 4, and TSH (84443) checks the thyroid. Here's what each code covers and how to get all five on one draw at any Quest.
Hera's female fertility hormone panel is $107 all-in: a physician order for the five tests, a blood draw at any Quest Diagnostics location, and nothing to pay at the lab. Order first, no location to pick. Within one business day we place the order with Quest and send you the go-ahead; then book a visit for day 2, 3 or 4 of your cycle.

CPT 82166 is anti-Müllerian hormone (AMH), made by the small follicles in the ovaries. It tracks how many eggs are left (ovarian reserve) and can be drawn on any day of the cycle. Fertility clinics use it mainly to predict how the ovaries will respond to IVF or egg-freezing medication. It is not a fertility verdict: in women trying to conceive naturally, a low AMH has not been shown to lower the chance of getting pregnant month to month.
FSH (83001), LH (83002) and estradiol (82670) are read early in the cycle, on day 2, 3 or 4, when they sit at their baseline. A high FSH is another sign of lower reserve; a high estradiol can push FSH down and make it look normal, which is why the two are drawn together. LH read against FSH is one of the things a doctor looks at for PCOS. TSH (84443) checks the thyroid, a common and treatable cause of irregular ovulation; if it is out of range the lab adds a free T4 (84439) automatically. One draw on day 2 to 4 covers all five.
1. Order the panel: $107, no location to choose. Hera's physician signs an order for all five tests (82166, 83001, 83002, 82670, 84443) and within one business day we place it in Quest's system and text or email you the go-ahead.
2. Book a visit at any Quest Diagnostics location (appointment.questdiagnostics.com) for day 2, 3 or 4 of your cycle, counting the first day of full flow as day 1. Bring a photo ID. No insurance card: the tests are billed to Hera's account with Quest, so there is nothing to pay at the lab.
3. Results come back to Hera in about 3 to 5 business days. We send them to you with the lab's reference ranges, and if anything needs a closer look we point you to the right next step, usually a fertility clinic.
Five tests, one blood draw on day 2 to 4 at any Quest, $107 all-in. Testing as a couple? Your partner can order a semen analysis through Hera at the same time.
Order the hormone panel — $107 at any Quest How couples test togetherA hormone panel is billed as one CPT line per test, so Hera's five-test panel is five lines (six if the free T4 reflex runs). If you are checking a bill, comparing a quote, or bringing an outside order to Quest, these are the codes to look for.
| Code | What it covers |
|---|---|
| 82166 (On a Hera order) | Anti-Müllerian hormone (AMH) — a read on the ovaries' remaining egg supply (ovarian reserve). Any cycle day. |
| 83001 | Follicle-stimulating hormone (FSH) — drawn on cycle day 2 to 4; a high baseline FSH also points to lower ovarian reserve. |
| 83002 | Luteinizing hormone (LH) — read against FSH; a high LH-to-FSH ratio is one sign doctors look at for PCOS. |
| 82670 | Estradiol — drawn with FSH on day 2 to 4; a high value can push FSH down and make it look normal. |
| 84443 | Thyroid-stimulating hormone (TSH) — thyroid problems can disrupt ovulation; any cycle day. |
| 84439 | Free T4 — added automatically by the lab only when the TSH is out of range. |
| 84146 | Prolactin — not in Hera's panel; a doctor adds it when periods are irregular or absent. |
| 84144 | Progesterone — not in Hera's panel; drawn about a week before the next period (day 21 of a 28-day cycle) to confirm ovulation. |
| Code | What it covers |
|---|---|
| Z31.41 (On a Hera order) | Encounter for fertility testing — the code on a Hera order. |
| N97.9 | Female infertility, unspecified — used once a couple has been trying for a year (six months at 35 or older). |
| N97.0 | Female infertility associated with anovulation — when cycles suggest ovulation is not happening. |
| E28.2 | Polycystic ovarian syndrome (PCOS). |
| N91.2 | Amenorrhea, unspecified — absent periods. |
Whether insurance pays follows the diagnosis code: N97.0, E28.2 or N91.2 are often covered, while Z31.41 fertility testing frequently is not. Hera's $107 panel is cash-pay by design, billed to Hera's Quest account and never to your insurance, so nothing shows up on an EOB.
CPT 82166 is AMH, 83001 is FSH, 83002 is LH, 82670 is estradiol and 84443 is TSH. Hera's panel orders all five on one draw. If the TSH is out of range, Quest adds a free T4 (84439) automatically. Prolactin (84146) and progesterone (84144) are separate tests a doctor adds for specific reasons.
No. AMH reflects how many eggs are left, not their quality, and in women trying to conceive naturally a low AMH has not been shown to lower the monthly chance of pregnancy. Where it matters most is IVF and egg freezing, where it predicts how many eggs the medication will produce. A low value is a reason to talk to a fertility specialist sooner, not a reason to stop trying.
FSH, LH and estradiol change across the cycle, and their reference ranges are set on samples from the start of it, when they sit at baseline. Day 1 is the first day of full flow, not spotting. AMH and TSH can be drawn any day, so one draw on day 2 to 4 covers the whole panel.
With irregular cycles, draw on day 2 to 4 of whichever period comes; with no periods at all, any day works and a doctor will usually add prolactin and testosterone. Hormonal birth control lowers FSH, LH and estradiol and can lower AMH, so the panel reads most clearly after you stop. If you are still on it, mention it when you look at the results.
That the ovaries need a stronger push from the pituitary to grow a follicle, a sign of lower ovarian reserve. It is read together with estradiol: a high estradiol on day 2 to 4 can push FSH into the normal range and hide that. A single high FSH is worth a conversation with a fertility clinic rather than a conclusion.
Often, when billed with a diagnosis such as anovulation (N97.0), PCOS (E28.2) or absent periods (N91.2), though many plans exclude fertility testing coded Z31.41. Hera's $107 panel is billed to Hera's Quest client account and never to your insurance, so there is no claim, no EOB and nothing to pay at the lab.
Cash prices for these five tests vary widely by lab and service, and are usually higher through a clinic visit. Hera's panel is $107 all-in at any Quest, physician order included, with nothing to pay at the lab.
Yes. About a third of couples who struggle to conceive have a factor on the male side, a third on the female side and the rest on both or unexplained, so testing one partner only answers half the question. A semen analysis is the male baseline, and Hera can order it at a lab near you.
