ICD-10: O12.11

The ICD-10 code O12.11 refers specifically to "Gestational proteinuria, first trimester." Here are some alternative names and related terms associated with this condition:

• Gestational Proteinuria: This is the broader term that encompasses proteinuria occurring during pregnancy, not limited to the first trimester.
• Pregnancy-Induced Proteinuria: This term highlights that the proteinuria is a result of pregnancy.
• First Trimester Proteinuria: This specifies the timing of the condition, indicating it occurs during the first trimester of pregnancy.
• Oedema and Proteinuria in Pregnancy: This term may be used in conjunction with gestational proteinuria, as it often occurs alongside other symptoms like oedema.
• Pre-eclampsia Indicator: While not synonymous, gestational proteinuria can be an early indicator of pre-eclampsia, a more severe condition that can develop later in pregnancy.

These terms help in understanding the condition and its implications during pregnancy, particularly in the context of monitoring maternal and fetal health.

The diagnosis of gestational proteinuria, specifically coded as O12.11 in the ICD-10 classification, is based on specific clinical criteria. Here are the key points regarding the diagnostic criteria for this condition:

• Definition: Gestational proteinuria refers to the presence of protein in the urine during pregnancy, particularly in the first trimester, which is classified under the ICD-10 code O12.11. This condition is often associated with gestational edema and is a significant marker for potential complications during pregnancy [3].

• Clinical Assessment: The diagnosis typically involves a urine test that detects protein levels. A significant amount of protein in the urine (usually more than 300 mg in a 24-hour urine collection) is indicative of proteinuria [3].

• Exclusion of Other Conditions: It is essential to rule out other causes of proteinuria, such as pre-existing kidney disease or other medical conditions that could contribute to protein levels in the urine. This ensures that the proteinuria is indeed gestational and not due to other underlying health issues [3].

• Monitoring: Continuous monitoring of blood pressure and urine protein levels is crucial, especially as the pregnancy progresses, to identify any potential development of conditions like preeclampsia, which is characterized by hypertension and proteinuria after 20 weeks of gestation [5][6].

In summary, the diagnosis of O12.11 involves urine protein testing, clinical evaluation, and monitoring for other potential complications during the first trimester of pregnancy.
