Urinary calculus, unspecified

This code signifies the presence of a calculus (stone) within the urinary tract when the specific location or type of stone is not documented. It indicates a general diagnosis of urinary stone disease without further anatomical detail.

Use this code when the medical record clearly states "urinary calculus" or "kidney stone" but lacks information specifying its exact location (e.g., kidney, ureter, bladder) or composition. This code is appropriate when the provider's documentation is generalized and does not allow for a more specific anatomical assignment.

• Avoid using this code if the documentation specifies the location of the calculus (e.g., kidney, ureter, bladder); instead, use a more specific code from the N20 category.
• Query the provider for clarification on the stone's location if possible to allow for more precise coding.
• This code should be used as a last resort when no further anatomical detail can be obtained from the medical record.
