About coding trachoma
The ICD-10-CM code for trachoma is A71.9 (Trachoma, unspecified). The official index lists 7 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on A71.9.
Within A71, choose A71.9 (unspecified) only when documentation doesn't support a more specific option: initial stage of trachoma (A71.0) and active stage of trachoma (A71.1).
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.
