O92.3Agalactia

Billable / specific codeICD-10-CM

O92.3 is a billable, specific ICD-10-CM code for agalactia. It is valid for submission on a claim.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

  • Elective agalactia (O92.5)
  • Secondary agalactia (O92.5)
  • Therapeutic agalactia (O92.5)

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

  • Primary agalactia

Other codes that can never be billed with O92.3

These codes carry an Excludes1 note pointing at O92.3. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading O92.3 alone.

  • O92.5Suppressed lactation

Risk adjustment

O92.3 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

How O92.3 is indexed

Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to O92.3.

  • Lactation, lactatingfailed(complete)
