    C 531 Correct Answer Incorrect Answer
    D 315 Correct Answer Incorrect Answer

    Solution

    ‘colour doppler peripheral’ is coded as ‘156’………. (i) ‘peripheral venous carotid’ is coded as ‘269’ ……..(ii) ‘carotid imaging doppler’ is coded as ‘593’……… (iii) From (i) and (ii), code for ‘peripheral’ is 6. From (i) and (ii), code for ‘carotid’ is 9. Now it is clear that the code for ‘imaging’ is 3. So, code for ‘peripheral imaging carotid’ is ‘693’.
