Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Congenital prolapse of bladder mucosa
- Eagle-Barrett syndrome
Other codes that can never be billed with Q79.4
These codes carry an Excludes1 note pointing at Q79.4. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Q79.4 alone.
- Q64.7Other and unspecified congenital malformations of bladder and urethra
Risk adjustment
Q79.4 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.
