AHA Coding Clinic® for ICD-10-CM and ICD-10-PCS - 2022 Issue 4; New/Revised ICD-10-CM Codes
Acute and Chronic Metabolic Acidosis
Code E87.2, Acidosis, has been expanded to differentiate between acute and chronic metabolic acidosis. Four new codes have been created to identify acute metabolic acidosis, chronic metabolic acidosis, along with unspecified and other specified types of acidosis:E87.20, Acidosis, unspecified E87.21, Acute metabolic acidosis E87.22, Chronic metabolic acidosis E87.29, Other acidosis Metabolic acidosis occurs when there is an acid-base imbalance in the blood. There is either too much acid in the body or not enough acid being removed from the body. Treatment is dependent on the cause of the acid-base imbalance. Metabolic acidosis may cause...

Article Overview
This article covers an ICD-10-CM coding update related to acidosis and explains the broader clinical distinctions between acute and chronic metabolic acidosis. It is aimed at coders and reimbursement professionals who need to understand the scope of the diagnosis revision, the medical context behind each category, and how the discussion relates to chronic kidney disease and related clinical documentation.
Why This Topic Matters
The article helps readers recognize a diagnosis expansion that affects code selection and documentation interpretation for metabolic acidosis. It is relevant for accurate reporting in settings where kidney disease, hospitalization, and metabolic imbalance are part of the clinical record.
Article Sections
-
Diagnosis code expansion
Introduces the updated acidosis category and outlines the broad structure of the revised diagnosis group. It frames the change as a classification update for related metabolic conditions.
-
Metabolic acidosis overview
Provides a general clinical overview of metabolic acidosis and describes broad signs, causes, and treatment concepts. The discussion stays at a high level without detailing coding mechanics.
-
Acute metabolic acidosis
Summarizes the clinical context commonly associated with acute presentations and the kinds of underlying conditions discussed in the article. It also notes the article’s general treatment focus for this category.
-
Chronic metabolic acidosis
Describes chronic metabolic acidosis in relation to kidney disease and its broader effects on the body. The section also covers general long-term management themes.
-
Clinical example
Presents a sample encounter involving chronic kidney disease and metabolic acidosis and ties the scenario to the article’s coding discussion. It is included as the article’s applied example.
