Maternal care for damage to fetus by radiation, fetus 1

This code signifies maternal care provided due to actual or suspected fetal damage caused by radiation exposure, specifically when the pregnancy involves a single fetus or the first fetus in a multiple gestation. It indicates that the mother is receiving monitoring or intervention because of concerns about the impact of radiation on the developing fetus.

Apply this code when documentation confirms maternal care for a fetus exposed to radiation, such as during diagnostic imaging procedures (e.g., X-rays, CT scans) or therapeutic radiation treatments. The medical record should clearly state the suspected or confirmed radiation exposure and the subsequent maternal care related to potential fetal damage.

• Always assign an additional code from category Z77 to identify the specific type of radiation exposure.
• Ensure the medical record specifies "fetus 1" or a single gestation when using this code; otherwise, a different O35.6 subcategory may be more appropriate.
• Do not use this code for routine prenatal care in a patient with a history of radiation exposure if there are no current concerns about fetal damage.
