About coding Pharyngoconjunctival fever
The ICD-10-CM code for Pharyngoconjunctival fever is B30.2 (Viral pharyngoconjunctivitis).
Within B30 (viral conjunctivitis), B30.2 is specifically for viral pharyngoconjunctivitis. Related codes cover keratoconjunctivitis due to adenovirus (B30.0), conjunctivitis due to adenovirus (B30.1), acute epidemic hemorrhagic conjunctivitis (enteroviral) (B30.3), other viral conjunctivitis (B30.8) 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.
