Abnormal levels of other serum enzymes

This code indicates laboratory findings of elevated or decreased levels of serum enzymes not specifically classified elsewhere. These enzymes play various roles in metabolic processes, and their abnormal levels can signify underlying organ dysfunction, tissue damage, or disease states. Examples include elevated amylase or lipase (not specified as pancreatic), or abnormal levels of less common enzymes.

Use this code when documentation indicates abnormal serum enzyme levels that are not explicitly categorized by more specific ICD-10-CM codes (e.g., specific liver enzymes, cardiac enzymes, or pancreatic enzymes with a definitive diagnosis). This code is appropriate when the abnormal finding is significant but a definitive diagnosis for the underlying cause has not yet been established or is not documented. Documentation should clearly state the specific enzyme and its abnormal level.

• Do not use this code if a more specific code for the abnormal enzyme level exists (e.g., R74.0 for elevated transaminase levels).
• Always sequence this code after the definitive diagnosis if the abnormal enzyme level is a manifestation of a known condition.
• Avoid using this code if the abnormal enzyme level is transient, insignificant, or within normal limits for the patient's age/sex.
