J34.2

J34.2 — Deviated nasal septum

Billable / specific codeICD-10-CM

J34.2 is a billable, specific ICD-10-CM code for deviated nasal septum. 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.

congenital deviated nasal septum (Q67.4)

Inclusion terms

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

Deflection or deviation of septum (nasal) (acquired)

Excludes2 inherited from the categories above J34.2

Also inherited, and the opposite of Excludes1: these conditions are not part of J34.2, but a patient can have both, so you may code both.

Written on J34 — Other and unspecified disorders of nose and nasal sinuses

varicose ulcer of nasal septum (I86.8)

Risk adjustment

J34.2 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

J34.2 is named in 6 Medicare coverage policies — 6 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
