Deficiencies of internal organs

This legacy ICD-9-CM code broadly describes a functional impairment or inadequacy of one or more internal organs. It indicates that an organ is not performing its normal physiological duties effectively, leading to a deficit in its function. This can encompass a range of conditions where an internal organ's capacity is compromised.

This code was typically used when documentation indicated a general insufficiency or deficiency of an internal organ without a more specific diagnosis available in ICD-9-CM. It might have been applied in cases of chronic organ failure or dysfunction where the precise etiology or a more granular code was not specified or known at the time of coding.

• This is a very general code; always strive for a more specific ICD-9-CM code if available and supported by documentation.
• Avoid using this code if a definitive diagnosis for the organ deficiency (e.g., chronic kidney disease, heart failure) can be coded.
• In the transition to ICD-10-CM, this code's concepts are typically mapped to much more specific organ-system diagnoses.
