About coding Divergent concomitant strabismus
The ICD-10-CM code for Divergent concomitant strabismus is H50.10 (Unspecified exotropia). The official index lists 10 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on H50.10.
Within H50.1, choose H50.10 (Unspecified exotropia) only when documentation doesn't support a more specific option: monocular exotropia (H50.11), monocular exotropia with A pattern (H50.12), monocular exotropia with V pattern (H50.13), monocular exotropia with other noncomitancies (H50.14), alternating exotropia (H50.15), alternating exotropia with A pattern (H50.16), alternating exotropia with V pattern (H50.17) and alternating exotropia with other noncomitancies (H50.18).
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.
