Newborn affected by maternal conditions that may be unrelated to present pregnancy (P00) ICD-10-CM
The P00 code range covers newborn affected by maternal conditions that may be unrelated to present pregnancy with 14 ICD-10-CM diagnosis codes. 12 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Code First
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.
- any current condition in newborn
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.
- encounter for observation of newborn for suspected diseases and conditions ruled out Z05
- newborn affected by maternal complications of pregnancy P01
- newborn affected by maternal endocrine and metabolic disorders P70 P74
- newborn affected by noxious substances transmitted via placenta or breast milk P04

About the P00 Code Range
A newborn may be affected by a condition in the mother, even when that condition is unrelated to the current pregnancy.
P00 separates maternal diseases from injury, procedures, and other conditions. Its disease subdivisions distinguish high blood pressure, kidney and urinary tract disease, infections, circulatory and respiratory disease, and nutritional disorders.
P00.5 identifies maternal injury. P00.6 and P00.7 separate surgery from other medical procedures on the mother.
P00.8 divides other maternal conditions into periodontal disease, positive group B streptococcus colonization, and other conditions. P00.9 identifies an unspecified maternal condition.
