About coding conjugate palsy deviation
The ICD-10-CM code for conjugate palsy deviation is H51.0 (Palsy (spasm) of conjugate gaze).
Within H51 (other disorders of binocular movement), H51.0 is specifically for palsy (spasm) of conjugate gaze. Related codes cover Convergence insufficiency and excess (H51.1), Internuclear ophthalmoplegia (H51.2), other specified disorders of binocular movement (H51.8) and unspecified disorder of binocular movement (H51.9).
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.
