Q82.8 — Other specified congenital malformations of skin
Q82.8 is a billable, specific ICD-10-CM code for other specified congenital malformations of skin. 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.
- Ehlers-Danlos syndromes (Q79.6-)
Excludes2 — not included here, but may coexist
The excluded condition is not part of this code, but a patient can have both. You may code both.
- disorders of pyrophosphate metabolism (E83.82-)
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Abnormal palmar creases
- Accessory skin tags
- Benign familial pemphigus [Hailey-Hailey]
- Congenital poikiloderma
- Cutis laxa (hyperelastica)
- Dermatoglyphic anomalies
- Inherited keratosis palmaris et plantaris
- Keratosis follicularis [Darier-White]
Other codes that can never be billed with Q82.8
These codes carry an Excludes1 note pointing at Q82.8. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Q82.8 alone.
Risk adjustment
Q82.8 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.
Medicare coverage
Q82.8 is named in 5 Medicare coverage policies — 5 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
