About coding Newcastle disease
The ICD-10-CM code for Newcastle disease is B30.8 (Other viral conjunctivitis).
Within B30, choose B30.8 (Other viral conjunctivitis) only when documentation doesn't support a more specific option: keratoconjunctivitis due to adenovirus (B30.0), conjunctivitis due to adenovirus (B30.1), viral pharyngoconjunctivitis (B30.2), acute epidemic hemorrhagic conjunctivitis (enteroviral) (B30.3) and unspecified (B30.9).
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 124 (Other Disorders of the Eye with MCC or Thrombolytic Agent, relative weight 1.2471) and DRG 125 (Other Disorders of the Eye without MCC, relative weight 0.7702), in MDC 02 (Diseases and Disorders of the Eye), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
