Code Description

ICD-10 O22.2 is a billable code used to indicate a diagnosis of superficial thrombophlebitis in pregnancy.

Key Diagnostic Point:

Superficial thrombophlebitis in pregnancy is characterized by inflammation of the superficial veins, often accompanied by thrombosis. This condition can occur due to the physiological changes in the venous system during pregnancy, including increased blood volume and hormonal changes that lead to venous dilation. Pregnant individuals may experience localized pain, tenderness, and swelling along the affected vein, typically in the lower extremities. While superficial thrombophlebitis is generally less serious than deep vein thrombosis (DVT), it can still pose risks, particularly if it progresses or if there is a concurrent DVT. Management often includes symptomatic relief, such as warm compresses and analgesics, and in some cases, anticoagulation therapy may be indicated to prevent complications. It is crucial for healthcare providers to monitor for signs of progression to DVT, especially in high-risk patients, and to ensure appropriate documentation for accurate coding and billing.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between superficial thrombophlebitis and deep vein thrombosis (DVT)
  • Understanding the implications of anticoagulation therapy during pregnancy
  • Documenting associated symptoms and risk factors accurately
  • Navigating the coding guidelines for venous complications in pregnancy

Audit Risk Factors

  • Inadequate documentation of symptoms and clinical findings
  • Failure to differentiate between superficial and deep vein conditions
  • Incorrect application of anticoagulation therapy codes
  • Lack of follow-up documentation for ongoing management

Specialty Focus

Medical Specialties

Obstetrics and Gynecology

Documentation Requirements

Detailed documentation of the patient's symptoms, clinical findings, and treatment plan is essential. This includes noting the location of thrombophlebitis, any associated pain, and the patient's history of venous issues.

Common Clinical Scenarios

Common scenarios include a pregnant patient presenting with leg pain and swelling, diagnosed with superficial thrombophlebitis after ruling out DVT.

Billing Considerations

Coders should be aware of the potential for progression to DVT and ensure that all relevant clinical information is captured to support the diagnosis.

Maternal-Fetal Medicine

Documentation Requirements

High-risk pregnancy documentation should include a comprehensive assessment of the patient's venous health, history of thrombosis, and any anticoagulation therapy prescribed.

Common Clinical Scenarios

Complex maternal-fetal scenarios may involve patients with a history of thrombosis or those undergoing anticoagulation therapy during pregnancy.

Billing Considerations

High-risk coding requires careful attention to detail, particularly in documenting the rationale for anticoagulation and monitoring for complications.

Coding Guidelines

Inclusion Criteria

Use O22.2 When
  • According to official coding guidelines, O22
  • 2 should be used when superficial thrombophlebitis is diagnosed during pregnancy
  • Coders must ensure that the diagnosis is supported by clinical documentation and that any associated conditions are also coded appropriately

Exclusion Criteria

Do NOT use O22.2 When
No specific exclusions found.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of venous complications in pregnancy, improving the accuracy of diagnoses and treatment tracking. O22.2 provides a clear distinction between superficial and deep venous conditions, which is crucial for appropriate management.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of venous complications in pregnancy, improving the accuracy of diagnoses and treatment tracking. O22.2 provides a clear distinction between superficial and deep venous conditions, which is crucial for appropriate management.
