ICD-10 code for hydrops
From the official ICD-10-CM alphabetic index entry “Hydrops”. Page updated September 29, 2026.
About coding hydrops
The ICD-10-CM code for hydrops is R60.9 (Edema, unspecified). The official index lists 20 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on R60.9.
Within R60, choose R60.9 (Edema, unspecified) only when documentation doesn't support a more specific option: localized edema (R60.0) and generalized edema (R60.1).
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.
