Top 10 OB/GYN procedures

According to the latest census data, women make up slightly more than half of the U.S. population.

Anyone with female reproductive organs will typically see a gynecologist starting in their late teens to early 20s for annual woman wellness exams to address any issues related to women’s health and the female reproductive system.

Given the critical role gynecologists play in maintaining women’s health, we examined the top procedures performed by gynecologists and OB/GYNs, aka obstetrician-gynecologists.

What are the most common OB/GYN procedures?

The most common OB/GYN CPT codes account for more than 24.7 million procedures in 2021.

The top ten procedures can be classified into three main categories: office visits for evaluation and preventative services, diagnostic pregnancy procedures and general diagnostic procedures. 

Office visits for evaluation and management of established patients (CPT codes 99213 and 99214) and annual comprehensive preventive visits (CPT codes 99396 and 99395) are two of the most common types of procedures performed by OB/GYNs. The codes that fall under those buckets account for more than 12.7 million procedures, more than half of the total volume of procedures on the list. One of the critical roles OB/GYNs perform is addressing women’s health issues and performing annual wellness exams, so it’s unsurprising to see these codes dominate the list.

We also see multiple codes related to diagnostic pregnancy procedures, including ultrasound for pregnant uterus (CPT code 76816), urine pregnancy test (CPT code 81025) and fetal non-stress test (CPT 59025). All three procedures are routine procedures for pregnant people to confirm the pregnancy and monitor the health of the parent and fetus.

Rounding out the top ten most common procedures are more general diagnostic procedures that aid in treating patients. Venipuncture (CPT code 36415), commonly known as a blood draw, is the second most common procedure performed by OB/GYNs. Blood draws can aid with diagnosing a wide range of conditions and confirm a person is pregnant. Urinalysis by dipstick (CPT code 81002) and ultrasound transvaginal for non-obstetrical purposes (CPT code: 76830) are two additional diagnostic procedures that aid OB/GYNs in treating patients.

What does OB/GYN stand for?

OB/GYN encompasses two specialties – obstetrics and gynecology. The OB represents obstetrics, while the GYN represents gynecology.

Obstetricians are providers who specialize in pregnancy, from prenatal care to post-natal care. Gynecologists specialize in the female reproductive system.

Many providers specialize in both obstetrics and gynecology. These providers are frequently referred to as OB/GYNs. OB/GYNs can provide more comprehensive care to patients as they oversee care when a patient is pregnant and not pregnant. Some OB/GYNs may also serve as primary care providers, especially for female patients.
