About coding nose hemorrhage
The ICD-10-CM code for nose hemorrhage is R04.0 (Epistaxis). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on R04.0.
Within R04 (hemorrhage from respiratory passages), R04.0 is specifically for epistaxis. Related codes cover hemorrhage from throat (R04.1), hemoptysis (R04.2), hemorrhage from other sites in respiratory passages (R04.8) and unspecified (R04.9).
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 150 (Epistaxis with MCC, relative weight 1.4473) and DRG 151 (Epistaxis without MCC, relative weight 0.7615), in MDC 03 (Diseases and Disorders of the Ear, Nose, Mouth and Throat), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
