ICD-10 code for neonatal transient thyrotoxicosis

The ICD-10-CM code for neonatal transient thyrotoxicosis is P72.1 (Transitory neonatal hyperthyroidism).

Within P72 (other transitory neonatal endocrine disorders), P72.1 is specifically for transitory neonatal hyperthyroidism. Related codes cover neonatal goiter, not elsewhere classified (P72.0), other transitory neonatal disorders of thyroid function, not elsewhere classified (P72.2), other specified transitory neonatal endocrine disorders (P72.8) and transitory neonatal endocrine disorder, unspecified (P72.9).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 791 (Prematurity with Major Problems, relative weight 4.1075) and DRG 793 (Full Term Neonate with Major Problems, relative weight 4.2195), in MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
