Introduction: Why GYN Procedure Billing Codes Matter
In the world of gynecological care, billing accuracy is more than an administrative detail—it’s what keeps a practice financially healthy. Whether you’re performing a cervical biopsy or inserting an IUD, every procedure must be documented with the correct CPT and ICD-10 codes. In Maryland, practices also face the added challenge of navigating Medicaid MCO rules and private payer guidelines.
So, let’s dive into the essential GYN billing codes, how to use them properly, and how Maryland providers can avoid common billing pitfalls.

Maryland-Specific Billing Considerations
Know Your Medicaid MCO Requirements
Maryland’s Medicaid program is administered through MCOs like Priority Partners, Amerigroup, and Maryland Physicians Care. Each payer may have:
- Unique prior authorization rules
- Service limitations (e.g., one Pap smear per year)
- Specific documentation standards
Commercial Payers May Differ
Blue Cross, Aetna, Cigna, and others may bundle certain procedures or require modifiers like 25 or 59. Always check your payer contract.
Tips to Avoid Billing Denials
- Match ICD-10 to CPT precisely – If the diagnosis doesn’t support the procedure, expect a denial.
- Double-check documentation – Especially for procedures like endometrial biopsies and hysteroscopies.
- Use appropriate modifiers – Particularly when billing multiple services.
- Stay up to date – CPT and ICD-10 codes are updated yearly.
