This code description may also have Includes , Excludes , Notes, Guidelines, Examples and other information. When to institute phototherapy in the case of ABO incompatibility has been outlined by the American Academy of Pediatrics (AAP) Subcommittee on Hyperbilirubinemia: Management of Hyperbilirubinemia in the Newborn Infant 35 or More Weeks of Gestation. 2011. pp. Unlike Rh alloimmunization, direct antibody test results are positive in only 20-40% of infants with ABO incompatibility. 114. Weiner CP, Williamson RA, Wenstrom KD, Sipes S, Grant SS, Widness JA. All Affected Infants, i.e., those which are Coombs positive: Parents: Parents need to be aware that affected infants who may or may not have been anemic at birth (especially those who received one or more in utero erythrocyte transfusions) are at considerable risk for developing clinically significant anemia during the first 3-4 months of life. Free bilirubin (i.e., unconjugated bilirubin not bound to albumin) is thought to be the neurotoxic form of bilirubin. Due to maternal screening for this condition, these infants are almost recognized prior to delivery. Rh, ABO incompatibility) and congenital infection If mother is blood type O+, obtain infant blood type and direct antiglobulin test A bilirubin-albumin ratio of 7:1 is considered safe under most circumstances. “Identification of neonates at risk for hazardous hyperbilirubinemia: emerging clinical insights”. Since ABO incompatibility is much less predictable, serum bilirubin concentrations can be followed to see if significant hemolysis is actually occurring, and phototherapy can then be started in accordance with published guidelines. How ABO Incompatibility Is … Once sensitized, the Rh-negative mother will have an anamnestic response in future incompatible pregnancies that will lead to a more severe hemolysis in each successive pregnancy involving an Rh-positive infant. There is controversy about the utility of IVIG for hemolytic disease. Such an infant should be transferred as soon as possible to a high-level NICU for care if antenatal transfer to a perinatal center has not been possible. If you carry this protein, your blood is Rh positive. Similarly, double-bank phototherapy will expose more surface area than a single bank of lights and is therefore more effective. 2014. pp. Exchange transfusion with O-negative blood compatible with the mother to increase the hematocrit without further volume overload is preferred over simple transfusions; exchange transfusion will also decrease the bilirubin load. 134. Newborn , male, premature (33 weeks gestation , 1,400 grams) Z38.00 ABO isoimmunization of newborn 2016 2017 2018 2019 2020 2021 Billable/Specific Code Code on Newborn Record P55.1 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. Examples are tin mesoporphyrin, zinc protoporphyrin, chromium mesoporphyrin. Rh isoimmunization is when the blood from the baby makes the mother's body create antibodies that can harm the baby's blood cells. Intensive phototherapy with maximal exposure of body surface is most effective, including the combined use of conventional phototherapy with a supplemental fiberoptic phototherapy blanket under the infant. Mild to Moderately Affected Infants: Treatment of less severely affected infants starts with correction of hypotension and acidosis. In cases where a severely affected, anemic infant is anticipated (a rarity in recent years), packed type O Rh- blood cross-matched against maternal serum should be available for possible immediate booster transfusion (see Neonatal Blood Bank Procedure Manual). 14. It is an immune system reaction that takes place when an infant’s blood type is different from their mother’s type. ABO incompatibility is the most common maternal-fetal blood group incompatibility and the most common cause of hemolytic disease of the newborn (HDN). 1. vol. vol. Blood type and antibody screen on the mother’s blood. Are you sure your patient has hemolytic disease of the newborn? Rh factor is a protein that may be found on the surface of red blood cells. Iron supplementation is not likely to be needed immediately, especially if there have been previous, including intrauterine, transfusions. Pediatrics. After initial stabilization, the infant should be transferred to the NICU. University of Iowa Stead Family Children’s Hospital is part of University of Iowa Hospitals & Clinics. Peer Review Status: Internally Peer Reviewed. Millard DD, Gidding SS, Socol ML, et al. “Update on HDFN: new information on long-standing controversies”. Copyright © 2017, 2013 Decision Support in Medicine, LLC. 297-316. e83-e88. 2013. pp. vol. Exchange transfusion: Central access is necessary as is the use of blood products. Anemia without hyperbilirubinemia is not likely to be due to a hemolytic process, but rather to blood loss or other more unusual problems such as bone marrow failure. The complication to be avoided is bilirubin encephalopathy. Anti-D is the most common cause of hemolytic disease of the newborn (HDN) in the developing countries even after the introduction of anti-D immunoprophylaxis. Phototherapy: Phototherapy should begin as soon as the diagnosis of Rh incompatibility is confirmed. P55.1 is a valid billable ICD-10 diagnosis code for ABO isoimmunization of newborn.It is found in the 2021 version of the ICD-10 Clinical Modification (CM) and can be used in all HIPAA-covered transactions from Oct 01, 2020 - Sep 30, 2021. Epidemiologic features of Rh incompatibility: Hemolytic disease of the newborn is more common in whites (15% Rh negative) than in blacks (7% Rh negative), and is rare in IndoEurasians (2% Rh negative). Phototherapy (light in the 425- to 475-nm wavelength range, peak effect at 460 nm, in the blue spectrum) acts by changing the isomeric structure of the bilirubin molecule, resulting in a more water-soluble stereoisomer that can be excreted in urine and bile without first being conjugated in the liver, the rate-limiting step for bilirubin excretion in the bile. The most common neonatal problem today is that of anemia developing following discharge. 31. In order for bilirubin to be removed from the fetus it must remain unconjugated and lipid soluble so that it can be transported across the placenta for excretion by the mother. not sufficient for a term or late preterm infant with hemolysis because of the inadequate body surface area exposed to the light. A rate of rise greater than 5 mg/dL/24 h (or >0.5 mg/dL/h) is suggestive of hemolysis in anyinfant; therefore, clinical jaundice(bilirubin >5 mg/dL needed to be clinically visible) in the first 24 hours strongly suggests a hemolytic process. With rare exceptions, it is presently possible to prenatally detect all non-ABO affected fetuses by testing for antibodies in maternal blood. All Rights Reserved. Our mission is to provide practice-focused clinical and drug information that is reflective of current and emerging principles of care that will help to inform oncology decisions. We want you to take advantage of everything Cancer Therapy Advisor has to offer. The reduced rates of isoimmunization in Rh-negative mothers with ABO incompatibility were noted years ago in 1943 by Levine. Most commonly, the mother is blood type O and her baby is A or B; less often the mother will be Rh negative and the baby Rh-positive. This is effective even if hemolysis is severe. 2. Rh- antigen • Rh- system – LANDSTEINER – 1940 • Rhesus blood group antigens – C, c, D, E, e • Short arm of chromosome 1 • RH (D) – most immunogenic • Person lacking D-antigen called Rh-ve • Lewis and Kell • 38th day after conception • INDIA- incidence =8-10% A 'billable code' is detailed enough to be used to specify a medical diagnosis. (Questions the efficacy of IVIG in hemolytic disease), Stevenson, DK, Wong, RJ. Mild to Moderately Affected Infants: If the delivery room assessment of infants indicates that the infant is not severely affected but still has some concerning signs, these infants should be transferred to the NICU (or Intermediate Care Nursery if appropriate). Exchange Transfusion: The final intervention for severe hemolysis that is unresponsive to the above procedures, or in the presence of signs of acute bilirubin encephalopathy, is exchange transfusion. The serum albumin level is measured because unconjugated bilirubin binds to albumin. ABO incompatibility is less severe than Rh incompatibility because there are fewer group A or B antigen sites on neonatal red blood cells compared with Rh antigens, allowing sensitized A or B cells to survive longer in the infant’s circulation than with anti-Rh antibodies. here. (Review of all forms of hemolytic disease in the newborn, including antibody-mediated), Ross, MB, Alarcon, P. ” Hemolytic disease of the fetus and newborn”. The heme oxygenase system has protean effects, similar to nitric oxide pathways, so positive and negative consequences are difficult to predict. The mother will lack the A or B antigen which is positive in the indirect Coombs test. What other disease/condition shares some of these symptoms? Signs of acute bilirubin encephalopathy include lethargy, poor feeding, and hypotonia, progressing to irritability alternating with stupor, high-pitched cry, and hypertonicity with retrocollis and opisthotonus. 2010. pp. Albumin administration: Since bilirubin is primarily bound to albumin in the bloodstream, and it is free or unbound bilirubin that is available to enter and damage the central nervous system (bilirubin encephalopathy or kernicterus), ensuring an adequate serum albumin concentration is essential. Early and excessive jaundice: The most common symptoms are early (especially during the first 24 hours of life) and excessive jaundice, and positive antibody testing (Coombs, direct antibody test [DAT]). In the rare event that severe anemia is thought to be present and the infant's primary problem, a small exchange transfusion with packed red blood cells, 20-40 mL/kg given in the delivery room, may be indicated. Am J Obstet Gynecol 1991;165:546-553. Severely Affected Infants: Following transfer to the NICU most severely affected infants warrant having an umbilical or peripheral arterial catheter inserted for monitoring blood pressure, pH and blood gases. 2008. pp. The nomogram published by the AAP is quite useful. “Prevention and management of RhD isoimmunization”. Therefore, treatment (phototherapy or exchange transfusion) would be instituted earlier in an infant with a low serum albumin concentration than in one with a robust concentration. Breast-feeding can be supplemented with expressed breast milk or formula if the infant is having difficulty latching on; use of a breast shield may also be helpful. 31 More recent studies have demonstrated that the same protective effect of incompatibility extends to non-RhD isoimmunization, with lower rates than expected based on population at risk. Register now at no charge to access unlimited clinical news, full-length features, case studies, conference coverage, and more. This can cause a problem if the baby's blood enters the mother's blood flow. Minor blood group hemolytic disease is extremely rare, since the overall potency of minor blood groups in inducing antibodies is significantly lower when compared with that of Rh (D) antigen. What complications might you expect from the disease or treatment of the disease? 92. We hereby report a very rare case of severe neonatal anti-E hemolytic disease due to E minor blood group inc … You’ve read {{metering-count}} of {{metering-total}} articles this month. As a result, the baby will be affected by the antibodies being produced by the mother.Blood types are not the same from each other due to the small molecules found on the surface of the blood cells. Arch Dis Child Fetal Neonatal Ed. All rights reserved. (Although both total bilirubin and bilirubin/albumin ratio are strong predictors of acute and longterm outcome, bilirubin/albumin ratio does not improve prediction over total serum bilirubin alone), Kaplan, M, Hammerman, C, Vreman, HJ. Adverse effects of treatments are described above. Albumin, IVIG: An intravenous line is required for administration. 2009. pp. These infants are extremely ill and require massive support. Anemia, in contrast, can be present and produce symptoms before birth. P55.1 is a billable ICD code used to specify a diagnosis of aBO isoimmunization of newborn. “Hemolysis and hyperbilirubinemia in antiglobulin positive, direct ABO blood group heterospecific neonates”. Intravenous fluid administration for hydration is not generally needed unless the infant is being fed nothing by mouth for possible exchange transfusion or other reasons, or if albumin or intravenous immunoglobulin (IVIG) is to be administered. The usual dose of anti-Rh globulin given to the mother (300 µg) protects against up to 30 mL fetal whole blood (15 mL fetal red blood cells); if a larger hemorrhage is suspected because of apparent acute blood loss and shock in the infant, estimation of the amount transfused by a Kleihauer-Betke test on the mother’s blood is indicated to estimate the dose of anti-Rh globulin needed. CancerTherapyAdvisor.com is a free online resource that offers oncology healthcare professionals a comprehensive knowledge base of practical oncology information and clinical tools to assist in making the right decisions for their patients. Your use of this website constitutes acceptance of Haymarket Media’s Privacy Policy and Terms & Conditions. P55.1 is a billable diagnosis code used to specify a medical diagnosis of abo isoimmunization of newborn. The chance for this occurring again in future pregnancies is unpredictable. vol. Hemolysis due to … This may occur whether or not the infant had exchange transfusion, IVIG, or intrauterine transfusion. Moreover, ABO incompatibility acts as a protective barrier to the expression of Rh isoimmunization. Available for iPhone, iPad, Android, and Web. Although approximately 15% of pregnancies are a “set-up” for ABO incompatibility (mother O, baby A or B), a positive DAT result is seen in only about 30% of these (4%-5% of pregnancies), and significant hemolysis is seen in only about 15% of those, or 1% of all pregnancies. 127. This condition occurs when there is an incompatibility between the blood types of the mother and baby. Cord Blood Laboratory Determinations: Before the umbilical cord blood clots, an immediate blood sample should be drawn with a large gauge needle and syringe from the placental portion of the umbilical cord and placed in an EDTA anticoagulated tube (lavender top) and red top tube. Rh incompatibility is when a mother has Rh-negative blood and her baby has Rh-positive blood. Prophylaxis for maternal Rh isoimmunization is possible through administration of anti-Rh globulin to Rh-negative women after miscarriage or abortion, during each pregnancy at 28 weeks’ gestation, and after delivery of an Rh-positive infant. “Incidence, etiology, and outcomes of hazardous hyperbilirubinemia in newborns”. due to ABO isoimmunization Z38.01 P55.1 Newborn 2. Rh negative women are given injections of a medicine called Rh immune globulin (RhoGAM) to keep their body from making Rh antibodies. The Licensed Content is the property of and copyrighted by DSM. Hemolytic disease of the newborn has become a less and less common condition due largely to improved preventative measures such as the maternal administration of Rh immune globulin during the early 3rd trimester and the immediate postpartum period. 2004. pp. An infusion of D10W with maintenance electrolytes should be initiated through an arterial line or peripheral IV. Rh isoimmunization 1. Sometimes a mother with Rh-negative blood is pregnant with a baby that has Rh-positive blood. For this reason the limits of acceptable bilirubin concentrations change with age and overall status. Alpay F, Sarici SU, Okutan V, et al. (ABO hemolytic disease as an important cause of exaggerated hyperbilirubinemia). The code P55.1 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions. Early and excessive jaundice can also occur from polycythemia (hematocrit >60%-65%) or from a cephalohematoma or extensive bruising, all resulting in an excessive amount of hemoglobin to be broken down and processed; again test results for red blood cell antibodies are negative. ABO incompatibility is a complication that could possibly occur during pregnancy. Most recently fetal cordocentesis has been utilized with increasing success to detect and to treat fetal anemia, i.e., with intravascular transfusion, in pregnancies identified prenatally, perinatal mortality and morbidity have been significantly improved. J Pediatr. Blood type and DAT on the cord blood or infant blood, looking for antibody on the infant’s red blood cells. A full "two volume" exchange for hyperbilirubinemia should be delayed for several hours until the infant's initial condition has stabilized (see below). Pediatrics. Their infants should have weekly hematocrit and reticulocyte counts performed and receive simple packed erythrocyte transfusions (20-25 mL/kg of PRBCs) if clinical symptoms appear if Hb levels fall below 6-7 gm/dL without evidence of a reticulocytosis, i.e., reticulocyte count <1%, or <100,000 per µL. Ongoing controversies regarding etiology, diagnosis, treatment. For many years, the use of metalloporphyrins, competitive inhibitors of heme oxygenase (the initial and rate-limiting enzyme involved in heme degradation) has been proposed for the prevention of bilirubin production in infants with known hemolytic processes. 56. Hemolytic disease of the newborn is also called erythroblastosis fetalis. The 2021 edition of … vol. The usual way for a pregnant woman to be sensitized is through a previous pregnancy or unrecognized miscarriage, or through a blood transfusion of incompatible blood. What caused this disease to develop at this time? If you are able to confirm that the patient has hemolytic disease of the newborn, what treatment should be initiated? Effects of intravascular, intrauterine transfusions on prenatal and postnatal hemolysis and erythropoiesis in severe fetal isoimmunization. Copyright © 2020 Haymarket Media, Inc. All Rights Reserved The hematocrit should be followed weekly, with transfusion performed when the hematocrit is less than 22%-25% and/or the infant is symptomatic (e.g., poor weight gain, easily fatigued). Thus, significant jaundice in neonates who are A-B incompatible with their mothers but DAT test negative is often attributed to isoimmunization and another diagnosis is … As with criteria for phototherapy, criteria for exchange transfusion vary with infant age, gestation, associated illness, and albumin concentration, and is also outlined by the AAP in nomogram form. Sign in Fortunately, this is much less common today with modern antenatal diagnosis and treatment, including intrauterine intravascular transfusions, which prevent and even reverse these findings before birth. The risk of neurologic injury (bilirubin encephalopathy or kernicterus) is dependent on gestational age, postnatal age, and associated illness (presence of hemolysis, acidosis, sepsis, asphyxia, and perhaps the serum albumin concentration). If present, ascites may create ventilatory embarrassment and paracentesis should be considered. Although in the case of ABO incompatibility, the indirect antibody test may be positive (antibody present in the infant’s plasma); if the DAT result is negative, these infants are not at increased risk of hemolysis. P55.1 - ABO isoimmunization of newborn The above description is abbreviated. RH ISO IMMUNIZATION RH ALLO IMMUNIZATION RH NEGATIVE COMPLICATING PREGNANCY 2. 920-928. vol. The smear will frequently show microcytic spherocytes if an isoimmune hemolytic process is present. Each individual owns a combination of these tw… This excessive red blood cell destruction leads to hyperbilirubinemia because of slow conjugation of bilirubin by the liver. 157. “Management of hyperbilirubinemia in the newborn infant 35 weeks or more of gestation”. 358. o Day 1: consider isoimmunization (ex. Other causes of hemolysis, for example, hereditary spherocytosis or glucose-6-phosphate dehydrogenase deficiency may present with early and/or excessive jaundice, but the Coombs or DAT test is not positive. Outcome of previous pregnancies, i.e., fetal & neonatal deaths, prematurity, etc. What laboratory studies should you request to help confirm the diagnosis? Folic acid 50 µg orally daily may be helpful in maintaining the maximal hematocrit possible. Exchange transfusion is invasive, requires central venous access (generally through the umbilical vein, or vein and artery), and should only be undertaken in a neonatal intensive care unit (NICU) setting with experienced personnel, as there are risks associated with the procedure, even in an otherwise healthy infant. Although the rate of rise of bilirubin is fairly steady and predictable in Rh disease, in ABO incompatibility it is not; the bilirubin often rises quickly to 10-15 mg/dL during the first 24 hours, then plateaus at 15-20 mg/dL during the second day. Women who are blood type O have naturally occurring anti-A and anti-B antibodies, mostly of the IgM class but some IgG. The risk of serious morbidity is approximately 5%, whereas the risk of mortality in an otherwise healthy term infant is less than 0.5%. It is currently recommended by the AAP as of their 2004 publication, but its efficacy has been questioned. Although recommended in the 2004 AAP Committee statement, a Cochrane review in 2002 recommended trials of higher quality be performed before endorsing this therapy. 772-777. 164-168. Rh-isoimmunization (incompatibility to the Rh blood type) is preventable, and prevention is preferable to treatment. A positive direct Coombs test on the neonates blood with identification of a specific serum antibody known to be associated with hemolytic disease (some blood group antigens, e.g., Lewis are not) makes the diagnosis. Despite maximal support, mortality remains high in these infants. A double-volume exchange transfusion (160 mL/kg, with type O, Rh-negative blood compatible with the mother, irradiated and leukodepleted) will remove approximately 85% of the infant’s cells, as well as much of the antibody, and will reduce the total bilirubin load by approximately 25% by removing that which is circulating in the blood. ↓ See below for any exclusions, inclusions or special notations What are the adverse effects associated with each treatment option?
