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.

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.

Clinical Terms in This Code Range

Definitions from the National Library of Medicine for conditions coded in the P01 range.

Hydranencephaly

A congenital condition where the greater portions of the cerebral hemispheres and CORPUS STRIATUM are replaced by CSF and glial tissue. The meninges and the skull are well formed, which is consistent with earlier normal embryogenesis of the telencephalon. Bilateral occlusions of the internal carotid arteries in utero is a potential mechanism. Clinical features include intact brainstem reflexes without evidence of higher cortical activity. (Menkes, Textbook of Child Neurology, 5th ed, p307)

About the P01 Code Range

ICD-10 code P01 covers conditions where a newborn is affected by various maternal complications during pregnancy. These codes specify the impact on the baby caused by maternal issues such as premature rupture of membranes, multiple pregnancies, or abnormal amniotic fluid levels.

The ICD-10 code for newborn affected by maternal complications includes detailed categories: P01.0 for effects from incompetent cervix, P01.1 for premature rupture of membranes, and P01.2 for oligohydramnios—also known as MARCH syndrome or Hydranencephaly. P01.3 covers newborns impacted by polyhydramnios, linked to several conditions including muscular hypertrophy and congenital hepatomegaly. Codes like P01.5 address newborns from multiple pregnancies, including twins or triplets, while P01.6 is for those affected by maternal death. Other codes in this section identify less common or unspecified maternal complications, ensuring accurate documentation when these issues affect the newborn’s health. This classification helps medical coders precisely capture newborn conditions influenced by maternal pregnancy problems.
