Renal failure, unspecified

This code signifies a general diagnosis of kidney failure without further specification of its type (e.g., acute, chronic, or end-stage). It indicates a significant impairment in renal function where the kidneys are unable to adequately filter waste products from the blood.

Use this code when documentation clearly states "renal failure" but provides no additional details regarding its acuity, chronicity, or underlying cause. It is appropriate when the provider has not yet determined or documented the specific type of renal failure.

• Avoid using this code if more specific documentation of acute, chronic, or end-stage renal disease is available.
• Always query the provider for clarification if only "renal failure" is documented, to determine if a more specific code can be assigned.
• This code should be considered a last resort when no further information on the type of renal failure can be obtained.
