CP-1546Incorrect LOINC code for Estimated Fetal Weight Percentile for HadlockStatusFinal TextDate of Last Update2016/05/25Person AssignedDavid ClunieSubmitter NameDamien LeratSubmission Date2015/09/24Correction Number CP-1546Log Summary: Incorrect LOINC code for Estimated Fetal Weight Percentile for HadlockName of StandardPS3.16 2016bRationale for Correction:The code 33183-5 used in CID 12016 "Estimated Fetal Weight Percentile Equations and Tables" is described in LOINC not as "FWP by GA, Hadlock 1991" but as "Fetal body weight growth percentile estimated from gestational age by method of Campbell 1991 (US)".The LOINC reference to Campbell 1991 (as distinct from Campbell 1975 and Campbell 1977 used in other LOINC codes), is thought to refer to:Campbell WA, Nardi D, Vintzileos AM, Rodis JF, Turner GW, Egan JF. Transverse Cerebellar Diameter/Abdominal Circumference Ratio Throughout Pregnancy: A Gestational Age-Independent Method to Assess Fetal Growth. Obstetrics & Gynecology. 1991;77(6):893–6. Available at: .There is no code listed in LOINC for "FWP by GA, Hadlock 1991", as distinct from Hadlock 1985; these methods are different and refer to different papers.Accordingly, the use of LN:33183-5 in DICOM is retired, since its usage is historically ambiguous, new codes for the two methods are added, and a note is added to warn of the potential discrepancy and the need to consider the transmitted code meaning when interpreting LN:33183-5. The note is added to both the context group in which the code is used and Annex H, which summarizes the code meanings for LOINC codes used.The code in LOINC, 33190-0, is "Fetal body weight growth percentile estimated from gestational age by method of Hadlock 1985", so the abbreviation in the code meaning should be "GA", not "MA".

LN:33183-5 was previously included in this context group with a Code Meaning of "FWP by GA, Hadlock 1991", but is described in LOINC as "Fetal body weight growth percentile estimated from gestational age by method of Campbell 1991 (US)". Devices receiving LN:33183-5 may need to consult the Code Meaning value to determine whether the sender meant Hadlock 1991 or Campbell 1991. New codes have been defined to replace LN:33183-5 to resolve the potential ambiguity.DICOM Controlled Terminology Definitions (Normative)
