Code Classification

  • 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)

O99.12 is a billable diagnosis code used to specify a medical diagnosis of other diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism complicating childbirth. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

The code O99.12 is applicable to female patients aged 12 through 55 years inclusive. It is clinically and virtually impossible to use this code on a non-female patient outside the stated age range.

The following annotation back-references for this diagnosis code are found in the injuries and diseases index. The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10-CM code(s).

Code Edits

The Medicare Code Editor (MCE) detects and reports errors in the coding of claims data. The following ICD-10-CM Code Edits are applicable to this code:

  • Maternity diagnoses - The Medicare Code Editor detects inconsistencies in maternity cases by checking a patient's age and any diagnosis on the patient's record. The maternity code edits apply to patients age ange is 9–64 years inclusive (e.g., diabetes in pregnancy, antepartum pulmonary complication).
  • Diagnoses for females only - The Medicare Code Editor detects inconsistencies between a patient’s sex and any diagnosis on the patient’s record, these edits apply to FEMALES only .

  • ICD-9-CM Code: 649.31 - Coagulation def-deliv
    Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Patient Education


Blood Disorders

Your blood is living tissue made up of liquid and solids. The liquid part, called plasma, is made of water, salts and protein. Over half of your blood is plasma. The solid part of your blood contains red blood cells, white blood cells and platelets.

Blood disorders affect one or more parts of the blood and prevent your blood from doing its job. They can be acute or chronic. Many blood disorders are inherited. Other causes include other diseases, side effects of medicines, and a lack of certain nutrients in your diet.

Types of blood disorders include:

  • Platelet disorders, excessive clotting, and bleeding problems, which affect how your blood clots
  • Anemia, which happens when your blood does not carry enough oxygen to the rest of your body
  • Cancers of the blood, such as leukemia and myeloma
  • Eosinophilic disorders, which are problems with one type of white blood cell.

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.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
