Acidosis, unspecified

This code signifies a general metabolic derangement characterized by an excess of acid in the body fluids, leading to a decrease in blood pH. It indicates that the specific type or cause of acidosis has not been determined or documented.

This code is appropriate when documentation indicates acidosis without further specification of its etiology (e.g., metabolic, respiratory, lactic, renal tubular). It should be used when the provider has diagnosed acidosis but has not provided sufficient detail to code a more specific type.

• Always query the provider for a more specific type of acidosis if possible, as this code is less specific.
• Avoid using this code if the documentation clearly points to a specific type of acidosis (e.g., lactic acidosis, diabetic ketoacidosis).
• Consider sequencing this code as a secondary diagnosis when the underlying cause of the acidosis is known and coded separately.
