Code Description

ICD-10 O34.12 is a billable code used to indicate a diagnosis of maternal care for benign tumor of corpus uteri, second trimester.

Key Diagnostic Point:

O34.12 refers to maternal care for a benign tumor located in the corpus uteri during the second trimester of pregnancy. This condition may involve careful monitoring and management due to potential implications for both maternal and fetal health. Benign tumors, such as fibroids, can affect the uterine environment, potentially leading to complications such as abnormal fetal positioning, increased risk of cesarean delivery, or uterine scarring. The second trimester is a critical period for fetal development, and the presence of a tumor may necessitate additional imaging or interventions to ensure the safety of both mother and child. Regular prenatal visits are essential for assessing the growth of the tumor and its impact on the pregnancy. Maternal care may include counseling regarding the risks associated with the tumor, monitoring for symptoms such as pain or bleeding, and planning for delivery, especially if a cesarean section is indicated due to the tumor's size or location.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between benign and malignant tumors
  • Assessing the impact of previous cesarean deliveries on current pregnancy
  • Understanding the implications of uterine scarring on delivery options
  • Monitoring for potential complications related to tumor growth

Audit Risk Factors

  • Inadequate documentation of tumor size and location
  • Failure to note previous obstetric history, including cesarean deliveries
  • Lack of detailed prenatal visit notes regarding tumor monitoring
  • Misclassification of tumor type (benign vs. malignant)
