About coding retention fluid
The ICD-10-CM code for retention fluid is R60.9 (Edema, unspecified).
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.
