Coding tips for Twin Pregnancy ICD 10 and CPT codes

Basic about twin pregnancy ICD 10 and Cpt Codes

As we know there are OB CPT codes using for coding Pregnancy procedures. The procedures are divided on weeks of gestation. There are separate pregnancy ICD 10 and CPT codes for first ,second and third trimester. The first trimester of pregnancy is week 1 through week 12, or about 3 months. The second trimester is week 13 to week 27. And the third trimester of pregnancy spans from week 28 to the birth. Now, the pregnant women can come at any time to the physician during pregnancy if there are any complications. The patient can also come for any follow up exam. So, the whole idea here to learn how to code when there is more than one fetus. Let check out the pregnancy ICD 10 and CPT code for twin delivery.

Cpt Code for twin gestation

For normal single fetus, we have to code only on CPT code but when there is more than one fetus, we will code an add-on code. This add-on can be used as many times depending on the number of fetus. The only criteria are the presence of all features present in the report for coding complete exam. If there are any missing criteria for OB complete, we will code limited 76815 CPT codes. The CPT code 76815 is used to code only once even for multiple gestation because the code description for 76815 say one or more fetus. Let us check out the complete description of the OB CPT codes.

76815 – OB ultrasound: limited one or more fetus
76801– OB ultrasound, Transabdominal less than 14 weeks of gestation: complete first gestation
76805– OB ultrasound, Transabdominal, more than 14 weeks of gestation; complete first gestation
76817– OB Ultrasound Transvaginal

For multiple gestations, we have add-on CPT codes used with 76801 and 76805.

76802– OB ultrasound, less than 14 weeks of gestation: additional gestation
(Should be used only with 76801 CPT code)

76810– OB ultrasound, more than 14 weeks of gestation; additional gestation
(Should be used only with 76805)

We also have a follow up CPT code for OB ultrasound, which is 76816

 76816– OB ultrasound; Follow-up

How to use OB CPT codes

Now as we know the above CPT code we will try to use these use codes with some examples

1.  If a patient has twin pregnancy of 10 weeks and comes for an OB ultrasound complete, we will code 76801 followed by 76802 CPT codes.

2.   If a patient has twin pregnancy of 20 weeks and comes for OB ultrasound complete, we will code 76805 followed by 76810 CPT codes.

3.   If a patient comes for a follow up exam for OB ultrasound, we will simple go ahead and code 76816 CPT code.

4.   If the physician performs a limited OB ultrasound on pregnant patient, we will code 76815 only even if there are multiple gestations.
