Venous complications and hemorrhoids in pregnancy (O22)

The O22 ICD-10 codes classify various venous complications and hemorrhoids during pregnancy, including varicose veins, thrombophlebitis, deep vein thrombosis, cerebral venous thrombosis, and hemorrhoids across pregnancy trimesters. These codes help specify the affected vein location and timing within the pregnancy.

This section includes detailed codes such as O22.0–varicose veins of the lower extremities, often known as "varicose veins of bilateral lower limbs in pregnancy"; O22.1 for genital varices or varicose veins of the vulva and perineum; and O22.2 for superficial thrombophlebitis, also called phlebitis or venous thrombosis in pregnancy. The category O22.3 addresses deep phlebothrombosis, a serious form of deep vein thrombosis during pregnancy. Hemorrhoids in pregnancy are coded under O22.4, while O22.5 covers cerebral venous thrombosis (sometimes termed cerebral venous sinus thrombosis). Codes also specify the trimester involved, providing critical guidance for clinicians and coders to accurately capture timing. The "other" and "unspecified" venous complications fall under O22.8 and O22.9, ensuring comprehensive coverage of venous disorders associated with pregnancy.

Instructional Notations

Type 1 Excludes

A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

  • venous complications of:
  • abortion NOS O03.9
  • ectopic or molar pregnancy O08.7
  • failed attempted abortion O07.35
  • induced abortion O04.85
  • spontaneous abortion O03.89

Type 2 Excludes

A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

  • obstetric pulmonary embolism O88
  • venous complications and hemorrhoids of childbirth and the puerperium O87
