Questions About P05.2Overview
Is P05.2 a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report newborn affected by fetal (intrauterine) malnutrition not light or small for gestational age on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does P05.2 group to?
When newborn affected by fetal (intrauterine) malnutrition not light or small for gestational age is the principal diagnosis on an inpatient stay, it groups to MS-DRG 793, 791, with relative weights from 4.1073 to 4.2192 depending on complications. Higher weights mean higher Medicare reimbursement.
Can P05.2 be reported with a code from P05.0?
Not as a rule. The Excludes1 note on P05.2 lists "newborn affected by fetal malnutrition with light for gestational age (P05.0-)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
What is the ICD-9 equivalent of P05.2?
Under the General Equivalence Mappings, newborn affected by fetal (intrauterine) malnutrition not light or small for gestational age converts to ICD-9-CM 764.20 (fetal malnutrition wtNOS). The mapping is approximate, so confirm the match fits the documentation.
