Moderate overall risk
Top issues: Bundled with OB ultrasound - should bill OB codes instead, Frequency limit exceeded - too many ultrasounds

1. Bundled with OB ultrasound - should bill OB codes instead

Common

76830 (transvaginal ultrasound) is for gynecologic evaluation, not obstetric. If patient is pregnant and ultrasound is for pregnancy dating/evaluation, should bill OB ultrasound codes (76801, 76805, etc.), not 76830. Denials occur when 76830 billed for pregnancy-related imaging.

Common Causes

  • Early pregnancy dating billed as 76830 instead of 76801
  • First trimester pregnancy evaluation using gynecologic code
  • Pelvic ultrasound on pregnant patient - confusion about correct code

Resolution Strategy

Recode to appropriate OB ultrasound code: 76801 (OB, first trimester, single fetus), 76805 (OB, after first trimester, single fetus). If truly gynecologic indication (pelvic pain, abnormal bleeding in non-pregnant patient), appeal with clear non-OB indication.

Appeal Success: Low

2. Frequency limit exceeded - too many ultrasounds

Common

Transvaginal ultrasound for fertility monitoring (follicle tracking) may have frequency limits (e.g., 1-2 per month). Payers deny when frequency exceeds policy limits unless medical necessity documented for more frequent monitoring.

Common Causes

  • Infertility treatment - multiple ultrasounds per cycle for follicle monitoring
  • Ovulation induction - frequent imaging to time IUI or intercourse
  • More ultrasounds than payer policy allows per month

Resolution Strategy

Review payer fertility benefit coverage. Many payers limit or exclude fertility treatment coverage including monitoring. Appeal with medical necessity for cycle monitoring if within policy limits. If policy excludes fertility coverage, patient responsibility.

Appeal Success: Low

Clinical Information

When to Use

Transvaginal ultrasound (TVUS) for detailed pelvic imaging - superior to transabdominal for uterus, ovaries, early pregnancy

Time Requirement
20-30 minutes for exam and documentation

Common Scenarios

Early pregnancy evaluation (< 10 weeks) - confirm intrauterine pregnancy, detect ectopic
Pelvic pain - evaluate for ovarian cysts, masses, ectopic pregnancy
Abnormal vaginal bleeding - assess endometrial thickness, uterine pathology
Infertility evaluation - follicle monitoring, uterine anatomy assessment
Suspected ovarian torsion or cyst rupture

Documentation Requirements

  • Clinical indication (pelvic pain, bleeding, pregnancy dating)
  • Structures visualized (uterus, ovaries, adnexa, cul-de-sac)
  • Measurements obtained (endometrial thickness, gestational sac if pregnant, ovarian cysts)
  • Radiologist or physician interpretation

Coding Guidelines

Common Modifiers

26 Professional component (physician interpretation)
TC Technical component (facility/equipment)

Bundling Rules

  • Includes complete pelvic evaluation - uterus, ovaries, adnexa
  • Cannot bill with transabdominal pelvic ultrasound (76856) unless separate clinical indication documented
  • If OB ultrasound for pregnancy, use OB ultrasound codes (76801, 76805, etc.) not 76830

Exclusions

  • Do not bill for pregnancy dating after first trimester (use OB ultrasound codes)
  • Cannot bill both transvaginal and transabdominal pelvic US same encounter without medical necessity
  • Follicle monitoring during fertility treatment may have frequency limits

Coding Notes

Superior imaging to transabdominal ultrasound for pelvic structures
Common in gynecology, early pregnancy, fertility practices
Higher RVU reflects specialized equipment and technique
Typically does not require prior authorization
