Specific Coding for Nasal polypOverview

Non-specific codes like J33 require more characters. Use one of these billable codes instead:

  • Use J33.0 for Polyp of nasal cavity

  • Use J33.1 for Polypoid sinus degeneration

  • Use J33.8 for Other polyp of sinus

  • Use J33.9 for Nasal polyp, unspecified

  • adenomatous polyps (D14.0)

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

From Chapter 10 (J00-J99) Diseases of the respiratory system applies to 366 codes
  • certain conditions originating in the perinatal period (P04-P96)
  • certain infectious and parasitic diseases (A00-B99)
  • complications of pregnancy, childbirth and the puerperium (O00-O9A)

  • symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)

Use Additional Code

Add a second code, after this one, to fully describe the condition.

From Chapter 10 (J00-J99) Diseases of the respiratory system applies to 366 codes
  • code, where applicable, to identify:
  • exposure to environmental tobacco smoke (Z77.22)
  • exposure to tobacco smoke in the perinatal period (P96.81)
  • history of tobacco dependence (Z87.891)
  • occupational exposure to environmental tobacco smoke (Z57.31)

Notes

General instructions on how these codes are used.

From Chapter 10 (J00-J99) Diseases of the respiratory system applies to 366 codes
  • When a respiratory condition is described as occurring in more than one site and is not specifically indexed, it should be classified to the lower anatomic site (e.g. tracheobronchitis to bronchitis in J40).

    polyp of nasal (cavity) (J33.-)

Clinical InformationClinical

Patient EducationClinical

Nose Injuries and Disorders

Your nose is important to your health. It filters the air you breathe, removing dust, germs, and irritants. It warms and moistens the air to keep your lungs and tubes that lead to them from drying out. Your nose also contains the nerve cells that help your sense of smell.

Questions About J33Overview

What is the ICD-10 code for nasal polyp?

J33 is the ICD-10-CM category for nasal polyp, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is J33 (Nasal polyp) a billable code?

No. This is a category header that groups the codes for nasal polyp, and headers cannot be submitted on claims. Claims for nasal polyp need a more specific code from this category, such as J33.0, J33.1, and J33.8.

Can J33 be reported with D14.0?

Not as a rule. The Excludes1 note on J33 lists "adenomatous polyps (D14.0)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
