J70 is a non-billable ICD-10-CM category code for respiratory conditions due to other external agents, so it cannot be submitted on claims. Use a more specific code from this category instead, such as J70.0, J70.1, J70.2, and J70.3.

Specific Coding for Respiratory conditions due to other external agentsOverview

Non-specific codes like J70 require more characters. Use one of these billable codes instead:

  • Use J70.0 for Acute pulmonary manifestations due to radiation

  • Use J70.1 for Chronic and other pulmonary manifestations due to radiation

  • Use J70.2 for Acute drug-induced interstitial lung disorders

  • Use J70.3 for Chronic drug-induced interstitial lung disorders

  • Use J70.4 for Drug-induced interstitial lung disorders, unspecified

  • Use J70.5 for Respiratory conditions due to smoke inhalation

  • Use J70.8 for Respiratory conditions due to other specified external agents

  • Use J70.9 for Respiratory conditions due to unspecified external agent

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to J70: its own notes plus those printed at block J60-J70 and Chapter 10. A note printed at a category, block or chapter applies to every code under it.

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 Block J60-J70 Lung diseases due to external agents applies to 45 codes
  • asthma (J45.-)
  • malignant neoplasm of bronchus and lung (C34.-)
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.

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).

Patient EducationClinical

Lung Diseases

When you breathe, your lungs take in oxygen from the air and deliver it to the bloodstream. The cells in your body need oxygen to work and grow. During a normal day, you breathe nearly 25,000 times. People with lung disease have difficulty breathing. Millions of people in the U.S. have lung disease.
