- Billable — Valid for Submission
- CC — Complication or Comorbidity
- Not Chronic
P70.8 is a billable ICD-10-CM diagnosis code for other transitory disorders of carbohydrate metabolism of newborn. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 794. As a secondary diagnosis, it counts as a complication or comorbidity (CC) and moves an inpatient stay to a higher severity level within its MS-DRG family. It does not count, however, when the principal diagnosis is one of 28 closely related codes. Coders also document this condition as fetal and/or neonatal perinatal disorder of glucose regulation. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Other specified and unspecified perinatal conditions.
