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).

Clinical InformationClinical

  • Bicornuate Uterus

    a congenital uterine anomaly in which the uterus is divided into two uterine horns with a significant cleft at the uterine fundus due to partial fusion of the mullerian ducts. bicornuate uterus is sometimes associated with a longitudinal vaginal septum and abnormal development of renal tracts.

  • Hemoglobinuria

    the presence of free hemoglobin in the urine, indicating hemolysis of erythrocytes within the vascular system. after saturating the hemoglobin-binding proteins (haptoglobins), free hemoglobin begins to appear in the urine.

  • Hemoglobinuria, Paroxysmal

    a condition characterized by the recurrence of hemoglobinuria caused by intravascular hemolysis. in cases occurring upon cold exposure (paroxysmal cold hemoglobinuria), usually after infections, there is a circulating antibody which is also a cold hemolysin. in cases occurring during or after sleep (paroxysmal nocturnal hemoglobinuria), the clonal hematopoietic stem cells exhibit a global deficiency of cell membrane proteins.

  • Hemoglobinuria, CTCAE|Hemoglobinuria|Hemoglobinuria|Hemoglobinuria, CTCAE 5.0

    a disorder characterized by laboratory test results that indicate the presence of free hemoglobin in the urine.

  • Blackwater Fever|Malarial Hemoglobinuria

    a complication of malaria resulting from hemolysis.

  • Grade 1 Hemoglobinuria, CTCAE|Grade 1 Hemoglobinuria|Grade 1 Hemoglobinuria

    asymptomatic; clinical or diagnostic observations only; intervention not indicated

  • Hemoglobinuria

    a laboratory test result which indicates free hemoglobin in the urine.

  • Hemoglobinuria due to Hemolysis from External Causes

    hemoglobin in the urine that is due to hemolysis from an external cause.

  • Paroxysmal Nocturnal Hemoglobinuria|PNH|PNH|Paroxysmal Hemoglobinuria|paroxysmal nocturnal hemoglobinuria

    a rare acquired hematologic disorder characterized by hemolytic anemia, dark-colored urine due to the release of hemoglobin in the blood, and thrombosis. the episodes of hemolysis tend to occur at night. it is caused by a somatic mutation in the glycosylphosphatidylinositol biosynthesis gene.

  • PIGA Gene Mutation|GPI3 Gene Mutation|MCAHS2 Gene Mutation|PIG-A Gene Mutation|PNH1 Gene Mutation|Paroxysmal Nocturnal Hemoglobinuria Gene Mutation|Phosphatidylinositol Glycan Anchor Biosynthesis Class A Gene Mutation

    a change in the nucleotide sequence of the piga gene.

    human piga wild-type allele is located in the vicinity of xp22.1 and is approximately 16 kb in length. this allele, which encodes phosphatidylinositol n-acetylglucosaminyltransferase subunit a protein, plays a role in the modulation of protein lipidation. mutation of the gene is associated with paroxysmal nocturnal hemoglobinuria.

Questions About O99.893Overview

Is O99.893 a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report other specified diseases and conditions complicating puerperium on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

Who can O99.893 be reported for?

The Medicare Code Editor checks other specified diseases and conditions complicating puerperium against patient demographics: this code is intended for maternity cases (age 9 through 64). Claims outside these limits are flagged as inconsistent.

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.
