About coding Convergence insufficiency
The ICD-10-CM code for Convergence insufficiency is H51.11 (Convergence insufficiency).
Within H51.1 (Convergence insufficiency and excess), H51.11 is specifically for Convergence insufficiency. Related codes cover excess (H51.12).
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.
