Free AAMA Certified Medical Assistant (CMA) Practice Question

A patient is seen for a painful swollen knee that the physician diagnoses as prepatellar bursitis. You are responsible for assigning the correct ICD-CM code. Which of the following codes should you use?

M22.4
M25.5
M70.4
M23.3

Report Issue

Answer Description

ICD-CM codes are used to describe diagnoses and conditions in a standardized format. For prepatellar bursitis, the specific code would be M70.4, which describes this condition. It's essential to select the most accurate and specific code available to ensure correct billing and to avoid insurance denials. The other options provided are incorrect and represent different conditions: M25.5 is a nonspecific code for pain in the joint, which does not specify bursitis, M22.4 describes patellar chondromalacia, and M23.3 covers meniscus derangements, which are different from prepatellar bursitis.
