How would you code a new pathological fracture of the right femur due to postmenopausal osteoporosis? a. M81.0 b. M80.851A c. M80.051A d. M84.551A

The correct code for a new pathological fracture of the right femur due to postmenopausal osteoporosis is M80.051A.

Here's why:

• M81.0 is the code for postmenopausal osteoporosis without current pathological fracture. Since the patient has a fracture, this code is not appropriate.

• M80.851A is the code for age-related osteoporosis with current pathological fracture, right femur, initial encounter for fracture. This code would be appropriate if the osteoporosis was age-related, but the question specifies that it is postmenopausal osteoporosis.

• M80.051A is the code for postmenopausal osteoporosis with current pathological fracture, right femur, initial encounter for fracture. This code is the most appropriate because it specifies that the osteoporosis is postmenopausal, there is a current pathological fracture, and it is in the right femur.

• M84.551A is the code for pathological fracture, right femur, initial encounter for fracture. This code does not specify the cause of the fracture, so it is not as accurate as M80.051A.
