Other methemoglobinemias

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

A condition where hemoglobin is converted to methemoglobin (an abnormal form that cannot carry oxygen effectively) due to various causes other than the unspecified category.

Coding Tips

  • •Identify and document the specific cause of methemoglobinemia (e.g., drug-induced, toxic exposure, or hereditary)
  • •If a specific cause is documented, use the appropriate D74.x code rather than the unspecified code
