About coding metabolic complication
The ICD-10-CM code for metabolic complication is E88.9 (Metabolic disorder, unspecified). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on E88.9.
Within E88, choose E88.9 (Metabolic disorder, unspecified) only when documentation doesn't support a more specific option: disorders of plasma-protein metabolism, not elsewhere classified (E88.0), lipodystrophy, not elsewhere classified (E88.1), Lipomatosis, not elsewhere classified (E88.2), tumor lysis syndrome (E88.3), mitochondrial metabolism disorders (E88.4), other specified metabolic disorders (E88.8) and wasting disease (syndrome) due to underlying condition (E88.A).
Use an additional code for: codes for associated conditions.
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
