About J10.82
J10.82 is the ICD-10-CM diagnosis code for influenza due to other identified influenza virus with myocarditis. It belongs to category J10 (influenza due to other identified influenza virus), block J09-J18 (influenza and pneumonia) and chapter 10 (diseases of the respiratory system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
Within J10.8 (influenza due to other identified influenza virus with other manifestations), J10.82 is specifically for influenza due to other identified influenza virus with myocarditis. Related codes cover encephalopathy (J10.81), otitis media (J10.83) and other manifestations (J10.89).
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 865 (Viral Illness with MCC, relative weight 1.3485) and DRG 866 (Viral Illness without MCC, relative weight 0.8692), in MDC 18 (Infectious and Parasitic Diseases, Systemic or Unspecified Sites), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as 487.8 (influenza with other manifestations).
