Chronic respiratory disease originating in the perinatal period (P27) ICD-10-CM
The P27 code range covers chronic respiratory disease originating in the perinatal period with 5 ICD-10-CM diagnosis codes. 4 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

About the P27 Code Range
ICD-10 code section P27 covers chronic respiratory diseases that begin in the perinatal period, which is the time shortly before and after birth. These codes are used to classify persistent lung conditions affecting newborns, such as bronchopulmonary dysplasia and Wilson-Mikity syndrome.
The ICD-10 code for Wilson-Mikity syndrome (P27.0) identifies a specific chronic respiratory disease in infants. P27.1 is designated for bronchopulmonary dysplasia, including all severity levels of this chronic lung condition common in premature babies. Other less common or different chronic respiratory diseases starting around birth, like perinatal pulmonary fibroplasia, are captured under P27.8. When the respiratory disease cannot be precisely identified, P27.9 is used as the unspecified category. Incorporating synonyms such as chronic respiratory disease originating in perinatal period and related terms helps clarify coding choices for these perinatal lung disorders. This makes the ICD-10 code for chronic respiratory disease originating in the perinatal period indispensable for properly documenting and tracking newborn respiratory health issues.
