About coding Agalactia
The ICD-10-CM code for Agalactia is O92.3 (Agalactia). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on O92.3.
Within O92 (other disorders of breast and disorders of lactation associated with pregnancy and the puerperium), O92.3 is specifically for Agalactia. 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), Hypogalactia (O92.4), Suppressed lactation (O92.5), Galactorrhea (O92.6) and other and unspecified disorders of lactation (O92.7).
Don't report O92.3 together with the conditions in its Excludes1 note: Elective agalactia (O92.5), Secondary agalactia (O92.5) and Therapeutic agalactia (O92.5).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
