Q84.1

Q84.1 — Congenital morphological disturbances of hair, not elsewhere classified

Billable / specific codeICD-10-CMPOA exempt

Q84.1 is a billable, specific ICD-10-CM code for congenital morphological disturbances of hair, not elsewhere classified. 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.

Menkes' kinky hair syndrome (E83.09)

Inclusion terms

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

Beaded hair
Monilethrix
Pili annulati

Other codes that can never be billed with Q84.1

These codes carry an Excludes1 note pointing at Q84.1. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Q84.1 alone.

L67Hair color and hair shaft abnormalities

Risk adjustment

Q84.1 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 Q84.1 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 Q84.1.

Beaded hair(congenital)
Monilethrix(congenital)
Ringed hair(congenital)
Thrix annulata(congenital)
Trichostasis spinulosa(congenital)
Woolly, wooly hair(congenital) (nevus)
