About coding Acrocyanosis
The ICD-10-CM code for Acrocyanosis is I73.89 (Other specified peripheral vascular diseases). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on I73.89.
Within I73.8, choose I73.89 (Other specified peripheral vascular diseases) only when documentation doesn't support a more specific option: Erythromelalgia (I73.81).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 299 (Peripheral Vascular Disorders with MCC, relative weight 1.5842), DRG 300 (Peripheral Vascular Disorders with CC, relative weight 1.0464) and DRG 301 (Peripheral Vascular Disorders without CC/MCC, relative weight 0.7133), in MDC 05 (Diseases and Disorders of the Circulatory System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
