About coding Clammy skin
The ICD-10-CM code for Clammy skin is R23.1 (Pallor).
Within R23 (other skin changes), R23.1 is specifically for Pallor. Related codes cover Cyanosis (R23.0), Flushing (R23.2), spontaneous ecchymoses (R23.3), changes in skin texture (R23.4), other skin changes (R23.8) and unspecified skin changes (R23.9).
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 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.
