Wedge Pressure Measurement Documentation
Question:
The code 75889 falls under the venography CPT rules. I have the below documentation from an IR physician. The actual portion of the pressure measurements within the report, doesn't state the necessity. Doesn't he have to give me more than the below to support?
Pre-procedure diagnosis: Cirrhosis
Post-procedure diagnosis: Same
Indication: Suspected portal hypertension
Additional clinical history: None
Complications: No immediate complications.
IMPRESSION: Transjugular liver biopsy with 3 x 19-gauge core biopsy samples obtained. The corrected sinusoidal pressure (wedged hepatic vein pressure minus free hepatic vein pressure) is 9 mmHg.
Venography
Vein catheterized: Right hepatic vein
Indication for venography: Document catheter position
Findings: Patent right hepatic vein.
Pressure measurements
Pressure measurements were obtained via balloon occlusion catheter.
Mean right atrial pressure (mmHg): 7
Mean free hepatic vein pressure (mmHg): 9
Mean wedged hepatic vein pressure (mmHg): 18
