Chapter 10: Diseases of the respiratory system

J00-J99

Chapter 10 of the ICD-10-CM tabular list covers diseases of the respiratory system, codes J00-J99. It holds 471 codes across 11 blocks, of which 360 are billable and 111 are header codes that cannot go on a claim.

Excludes2 — not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

  • 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 secondary code to capture the detail described below.

  • 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

Additional guidance from the ICD-10-CM tabular list.

  • 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).

Risk adjustment in Chapter 10

123 of this chapter’s codes map to a CMS-HCC, which means the diagnosis carries a risk-adjustment payment when it is documented and coded to the level the record supports.

  • HCC 280 Chronic Obstructive Pulmonary Disease, Interstitial Lung Disorders, and Other Chronic Lung Disorders
  • HCC 213 Cardio-Respiratory Failure and Shock
  • HCC 282 Aspiration and Specified Bacterial Pneumonias
  • HCC 211 Respirator Dependence/Tracheostomy Status/Complications
  • HCC 283 Empyema, Lung Abscess
  • HCC 276 Lung Transplant Status/Complications
