P92.1Regurgitation and rumination of newborn

Billable / specific codeICD-10-CM

P92.1 is a billable, specific ICD-10-CM code for regurgitation and rumination of newborn. It is valid for submission on a claim.

Other codes that can never be billed with P92.1

These codes carry an Excludes1 note pointing at P92.1. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading P92.1 alone.

Risk adjustment

P92.1 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 P92.1 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 P92.1.
