About coding Sclerokeratitis
The ICD-10-CM code for Sclerokeratitis is H16.8 (Other keratitis). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on H16.8.
Within H16, choose H16.8 (Other keratitis) only when documentation doesn't support a more specific option: corneal ulcer (H16.0), other and unspecified superficial keratitis without conjunctivitis (H16.1), keratoconjunctivitis (H16.2), interstitial and deep keratitis (H16.3), corneal neovascularization (H16.4) and unspecified keratitis (H16.9).
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.
