2021 ICD-10-CM Code I99.8
Other disorder of circulatory system
Valid for Submission
I99.8 is a billable diagnosis code used to specify a medical diagnosis of other disorder of circulatory system. The code I99.8 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.
The ICD-10-CM code I99.8 might also be used to specify conditions or terms like abnormality of hepatic vein, acquired arteriovenous malformation, acute vascular insufficiency, acute visceral ischemia, alteration in tissue perfusion , arterial ischemia, etc.

Diagnostic Related Groups - MS-DRG Mapping
The ICD-10 code I99.8 is grouped in the following groups for version MS-DRG V38.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC). applicable from 10/01/2020 through 09/30/2021.
Convert I99.8 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code I99.8 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.
