Is Q82 a billable ICD-10-CM code?

No. Q82 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does Q82 sit in the tabular list?

Congenital malformations, deformations and chromosomal abnormalities (Q00-QA0), in the block Other congenital malformations (Q80-Q89).

What cannot be coded together with Q82?

Q82 carries Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter.

Q82

Q82 — Other 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.

E79Disorders of purine and pyrimidine metabolism
I78.1Nevus, non-neoplastic
I89Other noninfective disorders of lymphatic vessels and lymph nodes
L85.1Acquired keratosis [keratoderma] palmaris et plantaris
L81Other disorders of pigmentation
L11.0Acquired keratosis follicularis
R60Edema, not elsewhere classified
C96.2Malignant mast cell neoplasm

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 history

Q82 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.

Code to one of these instead Q82

9 child codes. Green means billable.
