About coding Oculogyric spasm
The ICD-10-CM code for Oculogyric spasm is H51.8 (Other specified disorders of binocular movement). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on H51.8.
Within H51, choose H51.8 (Other specified disorders of binocular movement) only when documentation doesn't support a more specific option: palsy (spasm) of conjugate gaze (H51.0), Convergence insufficiency and excess (H51.1), Internuclear ophthalmoplegia (H51.2) 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 123 (Neurological Eye Disorders, relative weight 0.822), 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.
