Code Description

ICD-10 O34.599 is a billable code used to indicate a diagnosis of maternal care for other abnormalities of gravid uterus, unspecified trimester.

Key Diagnostic Point:

O34.599 is used to document maternal care for various abnormalities of the gravid uterus that do not fall under more specific categories. This code encompasses conditions such as abnormalities of pelvic organs, previous cesarean sections, and uterine scarring. These abnormalities can complicate pregnancy and may require specialized monitoring and management. For instance, women with a history of cesarean delivery may face risks such as uterine rupture or placenta accreta in subsequent pregnancies. Uterine scarring, often resulting from prior surgeries, can lead to complications such as infertility or abnormal placentation. Proper documentation is crucial to ensure that the care provided is accurately reflected in the coding, which can impact patient management and reimbursement. The unspecified trimester designation indicates that the exact timing of the condition within the pregnancy is not clearly defined, necessitating careful clinical assessment and documentation.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of potential underlying conditions requiring thorough documentation.
  • Need for precise clinical details to differentiate from other obstetric codes.
  • Variability in clinical presentation and management based on individual patient history.
  • Potential for overlapping diagnoses that may confuse coding.

Audit Risk Factors

  • Inadequate documentation of the specific abnormality.
  • Failure to specify the trimester when applicable.
  • Misclassification of the condition leading to incorrect coding.
  • Lack of supporting clinical evidence for the diagnosis.
