ICD-10 code for hyperemia
From the official ICD-10-CM alphabetic index entry “Hyperemia (acute) (passive)”. Page updated September 29, 2026.
About coding hyperemia
The ICD-10-CM code for hyperemia is R68.89 (Other general symptoms and signs). The official index lists 11 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on R68.89.
Within R68.8, choose R68.89 (Other general symptoms and signs) only when documentation doesn't support a more specific option: early satiety (R68.81), decreased libido (R68.82), Chills (without fever) (R68.83) and jaw pain (R68.84).
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 947 (Signs and Symptoms with MCC, relative weight 1.261) and DRG 948 (Signs and Symptoms without MCC, relative weight 0.7835), in MDC 23 (Factors Influencing Health Status and Other Contacts with Health Services), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
