These codes could enable valuable research and surveillance of placenta accreta spectrum, a life\u2010threatening pregnancy complication that is increasing in incidence.<\/jats:p><\/jats:sec><jats:sec><jats:title>Objective<\/jats:title><jats:p>We sought to evaluate the validity of placenta accreta spectrum diagnosis codes that were introduced in ICD\u201010 and assess contributing factors to incorrect code assignments.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We calculated sensitivity, specificity, positive predictive value and negative predictive value of the ICD\u201010 placenta accreta spectrum code assignments after reviewing medical records from October 2015 to March 2020 at a quaternary obstetric centre. Histopathologic diagnosis was considered the gold standard.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Among 22,345 patients, 104 (0.46%) had an ICD\u201010 code for placenta accreta spectrum and 51 (0.23%) had a histopathologic diagnosis. ICD\u201010 codes had a sensitivity of 0.71 (95% CI 0.56, 0.83), specificity of 0.98 (95% CI 0.93, 1.00), positive predictive value of 0.61 (95% CI 0.48, 0.72) and negative predictive value of 1.00 (95% CI 0.96, 1.00). The sensitivities of the ICD\u201010 codes for placenta accreta spectrum subtypes\u2014 accreta, increta and percreta\u2014were 0.55 (95% CI 0.31, 0.78), 0.33 (95% CI 0.12, 0.62) and 0.56 (95% CI 0.31, 0.78), respectively. Cases with incorrect code assignment were less morbid than cases with correct code assignment, with a lower incidence of hysterectomy at delivery (17% vs 100%), blood transfusion (26% vs 75%) and admission to the intensive care unit (0% vs 53%). Primary reasons for code misassignment included code assigned to cases of occult placenta accreta (35%) or to cases with clinical evidence of placental adherence without histopatholic diagnostic (35%) features.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>These findings from a quaternary obstetric centre suggest that ICD\u201010 codes may be useful for research and surveillance of placenta accreta spectrum, but researchers should be aware of likely substantial false positive cases.<\/jats:p><\/jats:sec>","DOI":"10.1111\/ppe.13076","type":"journal-article","created":{"date-parts":[[2024,3,22]],"date-time":"2024-03-22T04:39:24Z","timestamp":1711082364000},"page":"435-439","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Validity of <scp>ICD<\/scp>\u201010 diagnosis codes for placenta accreta spectrum disorders"],"prefix":"10.1111","volume":"38","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3843-5398","authenticated-orcid":false,"given":"Anjali R.","family":"Jotwani","sequence":"first","affiliation":[{"name":"Department of Obstetrics and Gynecology Stanford University  Stanford California USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Deirdre J.","family":"Lyell","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology Stanford University  Stanford California USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2048-0879","authenticated-orcid":false,"given":"Alexander J.","family":"Butwick","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, Perioperative and Pain Medicine Stanford University  Stanford California USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wanjiru","family":"Rwigi","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology Stanford University  Stanford California USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8213-1319","authenticated-orcid":false,"given":"Stephanie A.","family":"Leonard","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology Stanford University  Stanford California USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,3,21]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajog.2018.09.042"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.bpobgyn.2020.07.011"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1097\/AOG.0000000000003793"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMcp1709324"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.4297\/najms.2011.358"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajog.2019.01.233"},{"key":"e_1_2_10_8_1","unstructured":"Administrative Simplification: Change to the compliance date for the International Classification of Diseases 10th revision (ICD\u201010\u2010CM and ICD\u201010\u2010PCS) medical data code sets.
