About coding postprocedural hypoparathyroidism
The ICD-10-CM code for postprocedural hypoparathyroidism is E89.2 (Postprocedural hypoparathyroidism).
Within E89 (postprocedural endocrine and metabolic complications and disorders, not elsewhere classified), E89.2 is specifically for postprocedural hypoparathyroidism. Related codes cover postprocedural hypothyroidism (E89.0), postprocedural hypoinsulinemia (E89.1), postprocedural hypopituitarism (E89.3), postprocedural ovarian failure (E89.4), postprocedural testicular hypofunction (E89.5), postprocedural adrenocortical (-medullary) hypofunction (E89.6) and other postprocedural endocrine and metabolic complications and disorders (E89.8).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 643 (Endocrine Disorders with MCC, relative weight 1.6139), DRG 644 (Endocrine Disorders with CC, relative weight 1.0044), DRG 645 (Endocrine Disorders without CC/MCC, relative weight 0.7459), 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 10 (Endocrine, Nutritional and Metabolic Diseases and Disorders) and 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.
