What is the ICD-10 code for transaminitis?

The ICD-10 code for transaminitis is R74.01, used for elevated liver transaminase levels without a known cause.

When should R74.01 be used?

Use R74.01 when ALT/AST levels are elevated and no underlying cause is identified after initial workup.

Documentation & Coding Risks

Avoid these common issues when documenting Transaminitis.

Documenting 'elevated LFTs' without specifics

Impact

Clinical: Inadequate clinical picture, Regulatory: Potential for coding errors, Financial: Risk of claim denials

Mitigation

Always include specific enzyme values, Document exclusion of common causes

Using R74.01 as the principal diagnosis when an underlying cause is known.

Impact

Reimbursement: May lead to incorrect DRG assignment and reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.

Mitigation

Identify and code the underlying cause as the principal diagnosis.

Principal Diagnosis Selection

Impact

Using R74.01 as principal when an underlying cause is identified.

Mitigation

Ensure thorough documentation of clinical workup and identified causes.
