Final answer:
Yes, separate underlying injuries are coded separately when a 'crush' code is used.
Step-by-step explanation:
Yes, when a 'crush' code is used, the separate underlying injuries are typically coded separately as well. The 'crush' code is used to identify the main mechanism of injury, while the separate underlying injuries are coded based on their specific nature and location.
For example, if a patient sustains a crush injury to their leg and also fractures their tibia, the 'crush' code would indicate the general mechanism of injury, while an additional code would be used to identify the tibia fracture.
It's important to code each injury separately to accurately capture the extent and nature of the patient's injuries for documentation and billing purposes.
