I99.9 - Unspecified disorder of circulatory system
| ICD-10: | I99.9 |
| Short Description: | Unspecified disorder of circulatory system |
| Long Description: | Unspecified disorder of circulatory system |
| Status: | Valid for Submission |
| Version: | ICD-10-CM 2023 |
| Code Classification: |
I99.9 is a billable ICD-10 code used to specify a medical diagnosis of unspecified disorder of circulatory system. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.
Unspecified diagnosis codes like I99.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.
