J01 is a non-billable ICD-10-CM category code for acute sinusitis, so it cannot be submitted on claims. Use a more specific code from this category instead, such as J01.00, J01.01, J01.10, and J01.11.

Specific Coding for Acute sinusitisOverview

Non-specific codes like J01 require more characters. Use one of these billable codes instead:

  • J01.0 for Acute maxillary sinusitis

  • Use J01.00 for Acute maxillary sinusitis, unspecified

  • Use J01.01 for Acute recurrent maxillary sinusitis

  • J01.1 for Acute frontal sinusitis

  • Use J01.10 for Acute frontal sinusitis, unspecified

  • Use J01.11 for Acute recurrent frontal sinusitis

  • J01.2 for Acute ethmoidal sinusitis

  • Use J01.20 for Acute ethmoidal sinusitis, unspecified

  • Use J01.21 for Acute recurrent ethmoidal sinusitis

  • J01.3 for Acute sphenoidal sinusitis

  • Use J01.30 for Acute sphenoidal sinusitis, unspecified

  • Use J01.31 for Acute recurrent sphenoidal sinusitis

  • J01.4 for Acute pansinusitis

  • Use J01.40 for Acute pansinusitis, unspecified

  • Use J01.41 for Acute recurrent pansinusitis

  • J01.8 for Other acute sinusitis

  • Use J01.80 for Other acute sinusitis

  • Use J01.81 for Other acute recurrent sinusitis

  • J01.9 for Acute sinusitis, unspecified

  • Use J01.90 for Acute sinusitis, unspecified

  • Use J01.91 for Acute recurrent sinusitis, unspecified

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to J01: its own notes plus those printed at block J00-J06 and Chapter 10. A note printed at a category, block or chapter applies to every code under it.

Includes

Further defines, or gives examples of, the content of the category.

  • acute abscess of sinus
  • acute empyema of sinus
  • acute infection of sinus
  • acute inflammation of sinus
  • acute suppuration of sinus

Excludes1

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

On J01 itself
From Block J00-J06 Acute upper respiratory infections applies to 35 codes
  • chronic obstructive pulmonary disease with acute lower respiratory infection (J44.0)

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.

On J01 itself
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)
  • congenital malformations, deformations and chromosomal abnormalities (Q00-Q99)
  • endocrine, nutritional and metabolic diseases (E00-E88)
  • injury, poisoning and certain other consequences of external causes (S00-T88)
  • neoplasms (C00-D49)
  • smoke inhalation (T59.81-)
  • 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.

On J01 itself
  • code (B95-B97) to identify infectious agent.
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)
  • tobacco dependence (F17.-)
  • tobacco use (Z72.0)

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).

Referenced in Other NotesGuidance

Instructional notes printed at other codes that name J01, its category, or a range that includes it.

Excludes2 1

These codes carry an Excludes2 note naming J01: its condition is not part of those codes, and both may be reported when the patient has both.

  • J32 Chronic sinusitis
    acute sinusitis (J01.-)

Use Additional Code 3

These codes say to use an additional code from the note, and J01 is one of the codes named.

  • J09.X2 Influenza due to identified novel influenza A virus with other respiratory manifestations
    sinusitis (J01.-)
  • J10.1 Influenza due to other identified influenza virus with other respiratory manifestations
    code for associated sinusitis, if applicable (J01.-)
  • J11.1 Influenza due to unidentified influenza virus with other respiratory manifestations
    code for associated sinusitis, if applicable (J01.-)

Code Also 1

These codes say J01 may also be needed to fully describe the condition. The note gives no sequencing direction.

  • D81.82 Activated Phosphoinositide 3-kinase Delta Syndrome [APDS]
    other acute respiratory tract infections (J00-J06; J20-J22) names J00-J06, which includes this code

Clinical InformationClinical

  • Acute Sinusitis

    sinusitis lasting less than or equal to thirty days.

Patient EducationClinical

Sinusitis

Sinusitis means your sinuses are inflamed. The cause can be an infection or another problem. Your sinuses are hollow air spaces within the bones surrounding the nose. They produce mucus, which drains into the nose. If your nose is swollen, this can block the sinuses and cause pain.

Questions About J01Overview

What is the ICD-10 code for acute sinusitis?

J01 is the ICD-10-CM category for acute sinusitis, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is J01 (Acute sinusitis) a billable code?

No. This is a category header that groups the codes for acute sinusitis, and headers cannot be submitted on claims. Claims for acute sinusitis need a more specific code from this category, such as J01.00, J01.01, and J01.10.

Can J01 be reported with J32.9?

Not as a rule. The Excludes1 note on J01 lists "sinusitis NOS (J32.9)". 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).

Does J01 need an additional code?

When the condition applies, yes. The Use Additional Code note reads: code (B95-B97) to identify infectious agent.. The additional code is reported after J01.
