2025 ICD-10-CM code O99.0
(Active) Effective Date: N/A Pregnancy, childbirth and the puerperium - Other obstetric conditions, not elsewhere classified 15 Feed
Anemia complicating pregnancy, childbirth, and the puerperium.
The medical necessity for treating anemia complicating pregnancy, childbirth, or the puerperium is established by the presence of signs, symptoms, or laboratory findings indicating a deficiency in red blood cells or hemoglobin impacting the mother's health.Treatment is necessary to prevent further complications for both the mother and potentially the fetus/newborn.
The obstetrician or other healthcare provider managing the pregnancy is responsible for diagnosing and managing anemia in the pregnant woman. This includes ordering appropriate blood tests, prescribing necessary supplements like iron and other vitamins, and monitoring the patient's response to treatment.

- Other maternal diseases classifiable elsewhere but complicating pregnancy, childbirth and the puerperium (O99)
In simple words: This code indicates that a pregnant woman has a lower than normal red blood cell count, either during pregnancy, labor and delivery, or the period after delivery.
This code signifies a condition where a pregnant woman experiences anemia during pregnancy, childbirth, or the postpartum period (puerperium).It includes conditions classified under D50-D64 (excluding anemia arising in the puerperium (O90.81) and postpartum anemia NOS (O90.81)).This code is used only on the maternal record, not the newborn's.
Example 1: A woman in her second trimester of pregnancy presents with fatigue and pallor. Blood tests reveal low hemoglobin levels, indicating iron-deficiency anemia. She is prescribed iron supplements and her condition is monitored throughout the remainder of her pregnancy., A woman experiences significant blood loss during childbirth. Her hemoglobin levels drop significantly, and she is diagnosed with acute post-hemorrhagic anemia.She requires a blood transfusion and ongoing monitoring during the postpartum period., A pregnant patient is found to have a pre-existing condition such as sickle cell anemia that can be further complicated during pregnancy. O99.0 would be applied as a secondary code with the primary code specifying the underlying anemia type.
Documentation should include complete blood count (CBC) results showing low hemoglobin and hematocrit levels, the type of anemia if identified (e.g., iron-deficiency, folate deficiency), treatment provided (e.g., iron supplements, B12 injections), and the patient's response to treatment. If the anemia is caused or worsened by pregnancy, childbirth, or the puerperium, this relationship should be clearly documented.
