About coding papillitis
The ICD-10-CM code for papillitis is H46.00 (Optic papillitis, unspecified eye). The official index lists 7 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on H46.00.
Within H46.0, choose H46.00 (unspecified eye) only when documentation doesn't support a more specific option: right eye (H46.01), left eye (H46.02) and bilateral (H46.03).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
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.
