Inclusion terms

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

  • Congenital dislocatable hip

Risk adjustment

Q65.6 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 Q65.6 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 Q65.6.

  • Dislocatable hip, congenital
  • Predislocation status of hip at birth
  • Preluxation, hip, congenital
  • Subluxatable hip
