Inclusion terms

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

  • Non-deformational posterior plagiocephaly

Other codes that can never be billed with Q75.04

These codes carry an Excludes1 note pointing at Q75.04. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Q75.04 alone.

  • Q67.3Plagiocephaly
  • Q75.058Other multi-suture craniosynostosis

Risk adjustment

Q75.04 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.

Code to one of these instead Q75.04

3 child codes. Green means billable.
