Identify the ICD-9-CM diagnosis code for chondromalacia of the patella.

1. 717.7

2. 733.92

3. 748.3

4. 716.86

The correct answer is: 717.7

The code 717.7 specifically refers to chondromalacia of the patella, which is a condition characterized by the softening and damage of the cartilage on the kneecap (patella). This diagnosis is categorized under "Other and unspecified disorders of the meniscus," reflecting the condition's anatomical location and nature. Understanding the significance of the correct coding is essential for accurate medical record-keeping, insurance claims, and research purposes. Using the proper diagnosis code ensures that the condition is documented accurately within patient records and that healthcare providers receive appropriate reimbursement for the treatment of that specific condition. In contrast, the other codes provided would apply to different conditions. For instance, 733.92 is used for chondromalacia in general but does not specify the patella, and thus would not accurately reflect the diagnosis in question. The codes 748.3 and 716.86 relate to other anatomical sites and different conditions entirely, making them unsuitable for coding chondromalacia of the patella. Properly identifying and utilizing the diagnosis code is crucial for effective health information management.
