What is the ICD-10 code for familial hypophosphatemia?

The ICD-10 code for familial hypophosphatemia is E83.31, used when genetic testing confirms a familial cause.

How is acquired hypophosphatemia coded in ICD-10?

Acquired hypophosphatemia is coded as E83.39, provided the specific cause, such as diuretic use, is documented.

Documentation & Coding Risks

Avoid these common issues when documenting Hypophosphatemia.

Failing to document genetic confirmation for E83.31.

Impact

Clinical: Misclassification of genetic vs. acquired hypophosphatemia., Regulatory: Non-compliance with coding standards., Financial: Potential reimbursement issues.

Mitigation

Ensure genetic testing results are documented.

Using E83.39 without specifying the cause.

Impact

Reimbursement: May affect DRG assignment and reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate data on the cause of hypophosphatemia.

Mitigation

Document the specific cause of hypophosphatemia.

Documentation of underlying causes

Impact

Failure to document underlying causes can lead to audit findings.

Mitigation

Ensure comprehensive documentation of all contributing factors.
