Summary & Overview
HCPCS S4042: Management of Ovulation Induction, Per Cycle
HCPCS Level II code S4042 represents the per-cycle medical management of ovulation induction, encompassing interpretation of diagnostic tests and non-face-to-face clinical management. This code is relevant nationally as utilization of fertility services and care coordination for assisted reproduction grows, and payers increasingly define coverage and billing policies for cycle-based management services.
Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of what S4042 denotes clinically, common billing contexts and sites of service, and which payers commonly address ovulation induction management in coverage policies. The publication summarizes typical billing use — per cycle management of ovulation induction — and highlights where readers can expect variation across payers in coverage definitions and allowed settings.
The report provides: benchmarks and comparative coverage notes for major national payers; explanation of the clinical context for using S4042 alongside fertility treatment workflows; and a policy-oriented summary of how payers frame per-cycle management services. Data not available in the input is noted where applicable.

Clinical & Coding Specifications
Clinical Context
A 32-year-old woman with a history of irregular menstrual cycles and anovulation presents to a reproductive endocrinology clinic seeking fertility treatment. After initial evaluation (history, physical exam, transvaginal ultrasound, and baseline laboratories including serum progesterone, LH, FSH, and estradiol), the clinician initiates an ovulation induction cycle using oral clomiphene citrate or letrozole and/or injectable gonadotropins. The service labeled S4042 covers the non–face-to-face medical management of the ovulation induction cycle: interpretation of laboratory results and serial ultrasounds, adjustment of medication dosing, telephone or electronic communication with the patient regarding instructions and side effects, review of response to therapy, and documentation of cycle monitoring and plan. Typical workflow includes ordering and interpreting diagnostic tests, remote medication management, documenting dose changes, counseling on timing of intercourse or intrauterine insemination, and coordination of in‑clinic procedures as needed. Typical site of service is an outpatient fertility clinic or reproductive endocrinology office; portions of management may occur remotely (telehealth, telephone, electronic messaging) between face-to-face visits.
