Code Description

ICD-10 O12.11 is a billable code used to indicate a diagnosis of gestational proteinuria, first trimester.

Key Diagnostic Point:

Gestational proteinuria in the first trimester refers to the presence of excess protein in the urine of a pregnant woman during the early stages of pregnancy, specifically before the 14th week of gestation. This condition is often associated with gestational edema, which is the swelling caused by fluid retention. Unlike preeclampsia, gestational proteinuria in this context occurs without hypertension, making it a distinct clinical entity. The presence of proteinuria can be indicative of underlying renal issues or may simply be a physiological response to pregnancy. It is crucial for healthcare providers to monitor protein levels and assess for any potential complications, ensuring that the condition does not progress to more severe forms of gestational hypertension or preeclampsia later in pregnancy. Proper documentation of symptoms, laboratory findings, and any interventions is essential for accurate coding and management of the condition.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between gestational proteinuria and other forms of proteinuria.
  • Understanding the absence of hypertension in this diagnosis.
  • Monitoring and documenting changes in protein levels over time.
  • Recognizing the potential for progression to more severe conditions.

Audit Risk Factors

  • Inadequate documentation of proteinuria levels.
  • Failure to specify the absence of hypertension.
  • Misclassification of gestational proteinuria as preeclampsia.
  • Lack of follow-up documentation on the patient's condition.

Documentation Requirements

Documentation must include urine protein levels, any associated symptoms, and absence of hypertension.

Common Clinical Scenarios

A patient presents with swelling and proteinuria in the first trimester without elevated blood pressure.

Billing Considerations

Coders should ensure that all relevant laboratory results are included in the medical record.

Documentation Requirements

Detailed documentation of maternal and fetal health, including any risk factors for hypertension.

Common Clinical Scenarios

A high-risk patient with a history of renal issues presents with proteinuria in early pregnancy.

Billing Considerations

Consideration of potential complications and the need for close monitoring.
