About O92.3

O92.3 is the ICD-10-CM diagnosis code for Agalactia. It belongs to category O92 (other disorders of breast and disorders of lactation associated with pregnancy and the puerperium), block O85-O92 (complications predominantly related to the puerperium) and chapter 15 (pregnancy, childbirth and the puerperium). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

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.

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.

The Medicare Code Editor treats this as a maternity diagnosis, expected only for patients age 9 through 64.

It is on the CMS list of diagnoses consistent only with female patients (the sex-conflict edit itself was retired in FY2025).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 676.42 (failure of lactation, delivered, with mention of postpartum complication) and 676.44 (failure of lactation, postpartum condition or complication).
