ICD-10 code for Rivalta's disease

The ICD-10-CM code for Rivalta's disease is A42.2 (Cervicofacial actinomycosis).

Within A42 (actinomycosis), A42.2 is specifically for Cervicofacial actinomycosis. Related codes cover pulmonary actinomycosis (A42.0), abdominal actinomycosis (A42.1), actinomycotic sepsis (A42.7), other forms of actinomycosis (A42.8) and unspecified (A42.9).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 606 (Minor Skin Disorders with MCC, relative weight 1.5728), DRG 607 (Minor Skin Disorders without MCC, relative weight 0.8772), DRG 974 (HIV with Major Related Condition with MCC, relative weight 3.0506), DRG 975 (HIV with Major Related Condition with CC, relative weight 1.3252) and DRG 976 (HIV with Major Related Condition without CC/MCC, relative weight 0.8124), in MDC 09 (Diseases and Disorders of the Skin, Subcutaneous Tissue and Breast) and MDC 25 (Human Immunodeficiency Virus Infections), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
