  • Pregnancy, childbirth and the puerperium
    (O00-O9A)
    • Other obstetric conditions, not elsewhere classified
      (O94-O9A)
      • Other maternal diseases classifiable elsewhere but complicating pregnancy, childbirth and the puerperium
        (O99)

O99.4 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of diseases of the circulatory system complicating pregnancy, childbirth and the puerperium. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Diseases of the circulatory system compl preg/chldbrth

Non-specific codes like O99.4 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for diseases of the circulatory system compl preg/chldbrth:

  • O99.41 for Diseases of the circulatory system complicating pregnancy - NON-BILLABLE CODE

  • Use O99.411 for Diseases of the circulatory system complicating pregnancy, first trimester - BILLABLE CODE

  • Use O99.412 for Diseases of the circulatory system complicating pregnancy, second trimester - BILLABLE CODE

  • Use O99.413 for Diseases of the circulatory system complicating pregnancy, third trimester - BILLABLE CODE

  • Use O99.419 for Diseases of the circulatory system complicating pregnancy, unspecified trimester - BILLABLE CODE

  • Use O99.42 for Diseases of the circulatory system complicating childbirth - BILLABLE CODE

  • Use O99.43 for Diseases of the circulatory system complicating the puerperium - BILLABLE CODE

Tabular List of Diseases and Injuries

The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.


Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.

Type 1 Excludes

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.
  • peripartum cardiomyopathy O90.3

Type 2 Excludes

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.
  • hypertensive disorders O10 O16
  • obstetric embolism O88
  • venous complications and cerebrovenous sinus thrombosis in labor, childbirth and the puerperium O87
  • venous complications and cerebrovenous sinus thrombosis in pregnancy O22

Patient Education


Childbirth Problems

Childbirth is the process of giving birth to a baby. It includes labor and delivery. Usually everything goes well, but problems can happen. They may cause a risk to the mother, baby, or both. Some of the more common childbirth problems include:

  • Preterm (premature) labor, when your labor starts before 37 completed weeks of pregnancy
  • Premature rupture of membranes (PROM), when your water breaks too early. If labor does not start soon afterwards, this can raise the risk of infection.
  • Problems with the placenta, such as the placenta covering the cervix, separating from the uterus before birth, or being attached too firmly to the uterus
  • Labor that does not progress, meaning that labor is stalled. This can happen when
    • Your contractions weaken
    • Your cervix does not dilate (open) enough or is taking too long to dilate
    • The baby is not in the right position
    • The baby is too big or your pelvis is too small for the baby to move through the birth canal
  • Abnormal heart rate of the baby. Often, an abnormal heart rate is not a problem. But if the heart rate gets very fast or very slow, it can be a sign that your baby is not getting enough oxygen or that there are other problems.
  • Problems with the umbilical cord, such as the cord getting caught on the baby's arm, leg, or neck. It's also a problem if cord comes out before the baby does.
  • Problems with the position of the baby, such as breech, in which the baby is going to come out feet first
  • Shoulder dystocia, when the baby's head comes out, but the shoulder gets stuck
  • Perinatal asphyxia, which happens when the baby does not get enough oxygen in the uterus, during labor or delivery, or just after birth
  • Perineal tears, tearing of your vagina and the surrounding tissues
  • Excessive bleeding, which can happen when the delivery causes tears to the uterus or if you are not able to deliver the placenta after you give birth to the baby
  • Post-term pregnancy, when your pregnancy lasts more than 42 weeks

If you have problems in childbirth, your health care provider may need to give you medicines to induce or speed up labor, use tools to help guide the baby out of the birth canal, or deliver the baby by Cesarean section.
