About coding lacrimal system disorder
The ICD-10-CM code for lacrimal system disorder is H04.9 (Disorder of lacrimal system, unspecified). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on H04.9.
Within H04, choose H04.9 (Disorder of lacrimal system, unspecified) only when documentation doesn't support a more specific option: dacryoadenitis (H04.0), other disorders of lacrimal gland (H04.1), epiphora (H04.2), acute and unspecified inflammation of lacrimal passages (H04.3), chronic inflammation of lacrimal passages (H04.4), stenosis and insufficiency of lacrimal passages (H04.5), other changes of lacrimal passages (H04.6) and other disorders of lacrimal system (H04.8).
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.
