About coding acanthamoeba keratoconjunctivitis
The ICD-10-CM code for acanthamoeba keratoconjunctivitis is B60.13 (Keratoconjunctivitis due to Acanthamoeba).
Within B60.1 (Acanthamebiasis), B60.13 is specifically for keratoconjunctivitis due to Acanthamoeba. Related codes cover unspecified (B60.10), meningoencephalitis due to Acanthamoeba (culbertsoni) (B60.11), conjunctivitis due to Acanthamoeba (B60.12) and other acanthamebic disease (B60.19).
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.
