Final answer:
To code a right thigh injury, use the attribute of laterality. For a laparoscopic emergency appendectomy, use the attributes of priority and using access device.
Step-by-step explanation:
To code the case of a right thigh injury in SNOMED CT post-coordination syntax, you can use the attribute of 'laterality'. So the code for right thigh injury would be 840539000 |Injury of right thigh (disorder)|.
To code the case of a laparoscopic emergency appendectomy in SNOMED CT post-coordination syntax, you can use the attributes of 'priority' and 'using access device'. So the code for laparoscopic emergency appendectomy would be 169954006 |Laparoscopic emergency appendectomy (procedure)|. The attribute 'priority' indicates that it was an emergency procedure, and the attribute 'using access device' indicates that a laparoscope was used.
