Code Classification

  • Pregnancy, childbirth and the puerperium
    (O00-O9A)
    • Other maternal disorders predominantly related to pregnancy
      (O20-O29)
      • Maternal care for other conditions predominantly related to pregnancy
        (O26)

O26.899 is a billable diagnosis code used to specify a medical diagnosis of other specified pregnancy related conditions, unspecified trimester. 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 O26.899 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 code is commonly used in ob/gyn medical specialties to specify clinical concepts such as maternal disorders related to pregnancy.

Unspecified diagnosis codes like O26.899 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Clinical Classification

Clinical Information

  • Vasa Previa

    pregnancy complication where fetal blood vessels, normally inside the umbilical cord, are left unprotected and cross fetal membranes. it is associated with antepartum bleeding and fetal death and stillbirth due to exsanguination.
  • GAIA Level 1 Vasa Previa|Global Alignment of Immunization safety Assessment in pregnancy Level 1 Vasa Previa|Level 1 Vasa Previa

    gaia level 1 vasa previa is defined by two criteria: first, second trimester ultrasound evidence of fetal vessels (vessel with fetal heart rate identified by color flow doppler) traversing the membranes and overlying the internal cervical os; second, post-delivery examination of the placental specimen that demonstrates unsupported fetal vessels within the membranes.
  • GAIA Level 2 Vasa Previa|Global Alignment of Immunization safety Assessment in pregnancy Level 2 Vasa Previa|Level 2 Vasa Previa

    gaia level 2 vasa previa is defined by four criteria: first, vaginal bleeding during the second or third trimester at the time of ruptured amniotic membranes; second, fetal heart rate changes ultimately resulting in sinusoidal rhythm/terminal bradycardia; third, delivery of one of the following: a) a pale, anemic infant; or b) a recent stillbirth; or c) a neonatal death; fourth, post-delivery examination of the placental specimen that demonstrates unsupported fetal vessels within the membranes.
  • Vasa Previa

    umbilical blood vessels that have inserted into the amniotic membrane (membranous insertion) that in turn are above or adjacent to the cervical os and are at risk of rupture.

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 .

    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.

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.
