0.000What This Code Means
A long-standing blood clot in other major veins of the chest area that has persisted over time.
Coding Tips
- •Confirm chronic status is documented and differentiate from acute thoracic vein thrombosis
- •Identify the specific thoracic vein involved if documentation allows for greater specificity
Clinical Significance
Chronic thrombosis of thoracic veins indicates long-standing venous obstruction in the chest that may cause collateral circulation development and ongoing symptoms. These patients typically require sustained anticoagulation therapy and regular monitoring for complications including recurrence and post-thrombotic changes. Accurate capture reflects the persistent medical management needs of these patients.
Documentation Requirements
- ✓Clinical diagnosis of venous thrombosis or thrombophlebitis clearly documented by the treating provider
- ✓Diagnostic confirmation via duplex ultrasonography, CT venography, MR venography, or venography with imaging findings described
- ✓Current treatment plan including anticoagulation regimen with specific medication, dose, and duration
- ✓Documentation of chronic or long-standing nature of the thrombosis, including original date of diagnosis if available
- ✓Documentation of any associated central venous devices, malignancy, or precipitating factors
Commonly Confused Codes
I82.210/I82.211 — Superior vena cava thrombosis; SVC has its own specific codes and should not use 'other thoracic veins'I82.220/I82.221 — Inferior vena cava thrombosis; IVC is not a thoracic veinI82.B1x/I82.B2x — Subclavian vein thrombosis; has separate specific codesI80.8 — Phlebitis of other sites; use for thrombophlebitis rather than thrombosis/embolismI82.290 — Acute thoracic vein thrombosis; verify acuity
