The following are the scaling rules used by AMA:

General surgical are 100:50:25. Neurosurgical items LT045-LT275 and LT850-LT862 and orthopaedic items, except dislocations and fractures are 100:75:75

For multiple fractures requiring an operative or manipulative procedure, the fee for each is 100% and for multiple fractures where the second or subsequent conditions do not require operative or manipulative treatment, the fee for the second and each subsequent it’s 100:75:75. For repeat treatment for fractures, it’s 75% except for the final procedure which is 100%.

For multiple dislocations requiring an operative or manipulative procedure it’s 100% for each dislocation except where the second or subsequent dislocation does not need operative or manipulative treatment where it would be 75% for the subsequent dislocations. As with fractures, repeat procedures for dislocations are charged at 100% of the fee listed may be charged for the final procedure but 75% for the others.
