Diseases of the respiratory system

Use additional code

Report an additional code alongside this code to fully describe the condition. this code is sequenced first.

• 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)

Excludes2 — not included here

The conditions below are not part of this code, but a patient may have both at the same time. When documentation supports it, this code and the excluded code may both be reported.

• 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)

Note

• 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).
