Code Description

ICD-10 D68.5 is a billable code used to indicate a diagnosis of primary thrombophilia.

Key Diagnostic Point:

Primary thrombophilia refers to a group of inherited or acquired disorders that increase the risk of thrombosis due to abnormalities in the coagulation system. These conditions can lead to excessive clot formation in veins and arteries, resulting in complications such as deep vein thrombosis (DVT), pulmonary embolism (PE), and other thrombotic events. Common genetic factors include mutations in the Factor V gene (Leiden mutation) and prothrombin gene mutation, while acquired factors may include antiphospholipid syndrome. Patients with primary thrombophilia often present with a history of recurrent venous thromboembolism, and they may require long-term anticoagulation therapy to manage their condition. Diagnosis typically involves a combination of clinical assessment, family history, and specific laboratory tests to identify coagulation defects. Management strategies focus on preventing thrombotic events through lifestyle modifications and pharmacological interventions, including anticoagulants. Understanding the nuances of primary thrombophilia is crucial for effective patient management and coding accuracy.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of underlying genetic and acquired conditions
  • Need for comprehensive patient history and lab results
  • Potential for overlapping symptoms with other bleeding disorders
  • Variability in treatment protocols and monitoring requirements

Audit Risk Factors

  • Inadequate documentation of recurrent thrombotic events
  • Failure to document genetic testing results
  • Misclassification of primary vs. secondary thrombophilia
  • Lack of clear treatment plans in medical records

Frequently Asked Questions

What is the difference between primary and secondary thrombophilia?

Primary thrombophilia is typically inherited and results from genetic mutations affecting coagulation factors, while secondary thrombophilia is acquired due to conditions such as cancer, pregnancy, or certain medications.
