Our aim was to determine the accuracy of ICD-9 codes to identify newborns with HIE confirmed by umbilical cord blood analysis. &lt;i&gt;Methods:&lt;\/i&gt; ICD-9 codes in the newborn chart for birth trauma, birth asphyxia, intrauterine hypoxia, and fetal distress were used to identify newborns with suspected HIE by neonatal personnel. Maternal charts were reviewed for umbilical cord gases meeting the HIE clinical criteria. &lt;i&gt;Results:&lt;\/i&gt; There were 21,008 deliveries at center I and 17,540 at center II. ICD-9 codes identified 172 neonates, 49 infants (2.3\u2030 births) at center I and 123 neonates (7\u2030) at center II. Only 3 neonates (6%) were \u226734 weeks and none met ACOG criteria [umbilical artery pH &lt;7.00 or base excess (BE) \u226712 mmol\/l at center I]. At center II, 80 infants were \u226734 weeks but only 5\/123 (4%) met the ACOG clinical criteria for HIE (pH &lt;7.00, BE \u226712 mmol\/l, and Apgar \u22643 at 5 min). &lt;i&gt;Conclusions:&lt;\/i&gt; ICD-9 codes are unreliable in identifying birth asphyxia and cannot identify newborns meeting the clinical criteria for intrapartum HIE.<\/jats:p>","DOI":"10.1159\/000318204","type":"journal-article","created":{"date-parts":[[2011,4,26]],"date-time":"2011-04-26T06:56:19Z","timestamp":1303800979000},"page":"202-206","source":"Crossref","is-referenced-by-count":7,"title":["Does the International Classification of Disease (ICD-9) Code Accurately Identify Neonates Who Clinically Have Hypoxic-Ischemic Encephalopathy?"],"prefix":"10.1159","volume":"71","author":[{"given":"Gregory A.","family":"Vance","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amy","family":"Niederhauser","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Suneet P.","family":"Chauhan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Everett F.","family":"Magann","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joshua D.","family":"Dahlke","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jonathan K.","family":"Muraskas","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John C.","family":"Morrison","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2010,12,15]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.ajog.2004.12.058"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1097%2F00006250-200512000-00056"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.ajog.2008.06.096"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1111%2Fj.1651-2227.1995.tb13794.x"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1097%2F01.AOG.0000230533.62760.ef"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1016%2FS0029-7844%2802%2902211-1"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1097%2F00006250-200512000-00053"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1097%2FAOG.0b013e3181841395"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1055%2Fs-0028-1095185"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1080%2F14767050500073134"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1097%2FAOG.0b013e3181e7d267"}],"container-title":["Gynecologic and Obstetric Investigation"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/318204","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/318204","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T19:33:37Z","timestamp":1745436817000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000318204"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010,12,15]]},"references-count":11,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2011,4,1]]},"published-print":{"date-parts":[[2011,4,26]]}},"URL":"https:\/\/doi.org\/10.1159\/000318204","archive":["Portico"],"relation":{},"ISSN":["0378-7346","1423-002X"],"issn-type":[{"type":"print","value":"0378-7346"},{"type":"electronic","value":"1423-002X"}],"subject":[],"published":{"date-parts":[[2010,12,15]]}}}
