ICD-10: Z29.13

The ICD-10 code Z29.13 refers to an "Encounter for prophylactic Rho(D) immune globulin." This code is used in medical documentation to indicate a patient visit specifically for the administration of Rho(D) immune globulin, which is a critical intervention in certain clinical scenarios, particularly in obstetrics and gynecology. Below is a detailed overview of the clinical presentation, signs, symptoms, and patient characteristics associated with this encounter.

Clinical Presentation

Purpose of Rho(D) Immune Globulin

Rho(D) immune globulin is administered to Rh-negative individuals, particularly pregnant women, to prevent Rh immunization. This occurs when an Rh-negative mother is exposed to Rh-positive blood, which can happen during pregnancy, childbirth, or certain medical procedures. The administration of Rho(D) immune globulin helps to prevent the development of antibodies against Rh-positive blood cells, which can lead to hemolytic disease of the newborn (HDN) in future pregnancies.

Indications for Administration

• Pregnant Women: The primary indication for administering Rho(D) immune globulin is during pregnancy for Rh-negative women who may be at risk of Rh sensitization. This includes:
• Women with an Rh-positive fetus.
• Women who have had a miscarriage or abortion involving Rh-positive blood.
• Women who have experienced trauma or bleeding during pregnancy.
• Postpartum: It is also given within 72 hours after delivery if the newborn is Rh-positive.

Signs and Symptoms

Clinical Signs

Patients typically do not exhibit specific signs or symptoms directly related to the administration of Rho(D) immune globulin. However, the following may be observed in the context of the clinical scenario:
- Bleeding or Trauma: Signs of bleeding or trauma may be present if the administration is due to complications during pregnancy.
- Fetal Monitoring: In cases where fetal monitoring is conducted, signs of fetal distress may be assessed.

Symptoms

Patients may report:
- Anxiety or Concern: Many patients may express anxiety regarding their Rh status and the implications for their pregnancy.
- Mild Reactions: Some patients may experience mild side effects post-administration, such as soreness at the injection site, low-grade fever, or mild allergic reactions.

Patient Characteristics

Demographics

• Gender: Primarily female, as the indication for Rho(D) immune globulin is related to pregnancy.
• Age: Typically, patients are of childbearing age, often between 18 and 45 years old.

Medical History

• Rh Status: The patient must be Rh-negative.
