Q82Other congenital malformations of skin

Non-billable headerICD-10-CM

Q82 is a non-billable header ICD-10-CM code for other congenital malformations of skin. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

  • acrodermatitis enteropathica (E83.2)
  • congenital erythropoietic porphyria (E80.0)
  • pilonidal cyst or sinus (L05.-)
  • Sturge-Weber (-Dimitri) syndrome (Q85.89)

Other codes that can never be billed with Q82

These codes carry an Excludes1 note pointing at Q82. 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 alone.

  • L11.0Acquired keratosis follicularis
  • L81Other disorders of pigmentation
  • L85.1Acquired keratosis [keratoderma] palmaris et plantaris
  • R60Edema, not elsewhere classified
  • C96.2Malignant mast cell neoplasm
  • E79Disorders of purine and pyrimidine metabolism
  • D47.0Mast cell neoplasms of uncertain behavior
  • D47.01Cutaneous mastocytosis

Risk adjustment

Q82 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 Q82

9 child codes. Green means billable.
