About coding milk hypersecretion
The ICD-10-CM code for milk hypersecretion is O92.6 (Galactorrhea).
Within O92 (other disorders of breast and disorders of lactation associated with pregnancy and the puerperium), O92.6 is specifically for Galactorrhea. Related codes cover Retracted nipple associated with pregnancy, the puerperium, and lactation (O92.0), Cracked nipple associated with pregnancy, the puerperium, and lactation (O92.1), other and unspecified disorders of breast associated with pregnancy and the puerperium (O92.2), Agalactia (O92.3), Hypogalactia (O92.4), Suppressed lactation (O92.5) and other and unspecified disorders of lactation (O92.7).
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 769 (Postpartum and Post Abortion Diagnoses with O.R. Procedures, relative weight 1.6673) and DRG 776 (Postpartum and Post Abortion Diagnoses without O.R. Procedures, relative weight 0.6721), in MDC 14 (Pregnancy, Childbirth and the Puerperium), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
