About coding hemoptysis
The ICD-10-CM code for hemoptysis is R04.2 (Hemoptysis). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on R04.2.
Within R04 (hemorrhage from respiratory passages), R04.2 is specifically for hemoptysis. Related codes cover epistaxis (R04.0), hemorrhage from throat (R04.1), hemorrhage from other sites in respiratory passages (R04.8) and unspecified (R04.9).
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 204 (Respiratory Signs and Symptoms, relative weight 0.821), in MDC 04 (Diseases and Disorders of the Respiratory System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
