About coding blepharitis zoster herpes
The ICD-10-CM code for blepharitis zoster herpes is B02.39 (Other herpes zoster eye disease). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on B02.39.
Within B02.3, choose B02.39 (Other herpes zoster eye disease) only when documentation doesn't support a more specific option: unspecified (B02.30), zoster conjunctivitis (B02.31), zoster iridocyclitis (B02.32), zoster keratitis (B02.33) and zoster scleritis (B02.34).
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 124 (Other Disorders of the Eye with MCC or Thrombolytic Agent, relative weight 1.2471), DRG 125 (Other Disorders of the Eye without MCC, relative weight 0.7702), DRG 791 (Prematurity with Major Problems, relative weight 4.1075), DRG 793 (Full Term Neonate with Major Problems, relative weight 4.2195), DRG 974 (HIV with Major Related Condition with MCC, relative weight 3.0506), DRG 975 (HIV with Major Related Condition with CC, relative weight 1.3252) and 1 more, in MDC 02 (Diseases and Disorders of the Eye), MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period) and MDC 25 (Human Immunodeficiency Virus Infections), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
