About coding Lentiglobus
The ICD-10-CM code for Lentiglobus is Q12.8 (Other congenital lens malformations).
Within Q12, choose Q12.8 (Other congenital lens malformations) only when documentation doesn't support a more specific option: congenital cataract (Q12.0), congenital displaced lens (Q12.1), coloboma of lens (Q12.2), congenital aphakia (Q12.3), Spherophakia (Q12.4) and congenital lens malformation, unspecified (Q12.9).
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.
