What is the diagnostic code for ureterolithiasis?

• A. N20.1
• B. N20.0
• C. N20.2
• D. N20.9

Answer: (A)

The correct diagnostic code for ureterolithiasis, which refers specifically to stones located in the ureter, is indeed N20.1. This code is part of the International Classification of Diseases, Tenth Revision (ICD-10), which categorizes different medical conditions.

In this context, N20.1 is defined explicitly for ureterolithiasis, providing a clear and accurate representation of the condition for healthcare documentation and billing purposes. The differentiation in codes is essential for proper diagnosis, as each code corresponds to a specific type of urinary stone condition.

The other codes refer to different types of urolithiasis or related conditions:

• N20.0 refers to renal calculi, which are stones located in the kidney.

• N20.2 designates other urolithiasis not specified, covering broader types of urinary stones.

• N20.9 denotes unspecified urolithiasis, which is used when there is no specific information about the location or type of stone.

Using the correct code not only aids in accurate medical record keeping but also ensures appropriate treatment and resource allocation.
