No infertility benefit
The plan excludes infertility or caps lifetime cycles. Core MB verifies the rider, cycle count and drug coverage before stimulation starts and sets up self-pay package billing where coverage ends.

Fertility medical billing services
Fertility billing lives or dies on the benefit check. The same IVF cycle can be a covered medical service, a carve-out managed by a fertility benefit vendor, or a self-pay package, and the claim has to be built differently for each. Codes span surgical retrievals, embryology lab work, monitoring ultrasounds, drugs and S-code cycle reporting.
What makes fertility billing different
Reproductive endocrinology mixes office visits, procedures, lab work and pharmacy in one cycle, and payers rarely cover all of it the same way.
- Cycle services use S-codes such as S4011 for the IVF cycle, S4015 for a complete cycle, S4016 for a frozen cycle, S4020 and S4021 for canceled cycles and S4042 for ovulation induction management, often alongside the CPT components.
- Procedure codes include 58970 for oocyte retrieval, 58974 for intrauterine embryo transfer, 58322 for intrauterine insemination and 58323 for sperm washing, each paired with a diagnosis from the N97, N46 or Z31.8 families.
- Embryology codes in the 89250 to 89398 range carry their own rules: 89280 and 89281 for ICSI split at ten oocytes, 89258 and 89337 cover cryopreservation, and storage codes 89342 and 89346 usually bill to the patient.
- Monitoring ultrasounds billed as 76830 and 76857 are often limited per cycle, gonadotropins such as J3355, S0126, S0128 and S0132 need NDC and unit detail, and 58340 with 74740 for HSG requires the radiologic interpretation on file.
Denials we see most in fertility
Every denial gets a root cause, a fix and a feedback loop, so the same denial stops coming back.
Carve-out vendor not billed
Progyny, Carrot or WINFertility manages the benefit and the claim went to the medical plan. Core MB flags carve-out members at verification and routes authorizations and claims to the vendor's own process.
Diagnosis does not support cycle
Z31.83 or Z31.84 was billed without the underlying infertility or preservation diagnosis the policy requires. Core MB maps each cycle type to the diagnosis combination the payer's medical policy lists and corrects before submission.
How Core MB bills for fertility
Core MB assigns a biller who tracks each patient by cycle, not by date of service, so retrieval, lab work, transfer and medications reconcile against one authorization and one benefit limit. Credentialing for new physicians and embryology staff runs in the same client portal. Credentialing for new providers runs in the same system, tracked live in your client portal.
- Verification captures the infertility rider, lifetime cycle or attempt limits, drug coverage and any fertility benefit vendor before stimulation.
- Cycle worksheets tie S-codes, CPT components, lab codes and J-codes together so nothing is billed twice or missed.
- Self-pay package and insurance portions are split at posting so patient balances match the financial counselor's estimate.

Fertility billing questions
Do we bill both the S-code and the CPT codes for an IVF cycle?
It depends on the plan. Some commercial payers want the S4011 or S4015 cycle code as the primary line with component codes informational, others pay only itemized CPT and lab codes, and fertility benefit vendors have their own grids. Core MB keeps a payer-by-payer matrix and builds each claim to the format that plan actually adjudicates.
Why do our monitoring ultrasounds keep getting cut after the third one?
Many infertility riders limit 76830 or 76857 per cycle or per month, and some bundle monitoring into the cycle payment entirely. Core MB checks the limit during verification, tracks the count as the cycle progresses and moves additional scans to the patient's package or secures an authorization extension when the plan allows one.
A patient wants egg freezing before chemotherapy. How does that bill differently?
Fertility preservation uses Z31.84 with the cancer diagnosis and is covered under separate state mandates and plan language than infertility treatment. Core MB verifies the preservation benefit specifically, bills 58970 and 89337 against that benefit, and sets up storage charges 89346 as a patient responsibility where the plan does not cover them.
How do we get started with Core MB for fertility billing?
Use the quote form to tell us your cycle volume, payer mix and whether you use a fertility benefit vendor. We review your current claims and set a start date, and the transition runs alongside your current billing so no cycle is interrupted. Credentialing for new physicians can start at the same time in the same portal.
Billing that follows each fertility cycle from verification to transfer
Core MB helps reproductive endocrinology practices turn complicated cycle billing into clean claims, accurate patient packages and fewer surprises when coverage runs out.
