Radiology Coding Alert

Question: How should I code the following report? History: Lump over the upper right back. Findings: Real-time gray scale, color, and duplex Doppler imaging is performed for evaluation of a nodule over the upper right back measuring approximately 1.4 x 0.4 x 1.4 cm. Color Doppler imaging demonstrates moderate internal vascular flow. Duplex Doppler imaging demonstrates internal both venous and arterial flow. A large vessel appears to enter the superior margin of the mass. The surrounding fascia planes are well defined. There is an oval nodule that is moderately deep to the skin surface and overlies the musculature, exhibiting both internal arterial and venous blood flow. There appears to be a supplying artery and draining vein. Sonographic characteristics are not compatible with arterial venous malformation although some type of vascular lesion is undoubtedly present. Considerations include a hemangioma, mixed arterial venous malformation, or possibly a mass with high internal vascular [...]
