E61.5

What This Code Means

Molybdenum deficiency is a rare nutritional condition where the body lacks sufficient molybdenum, a mineral needed for certain enzyme functions. This condition is extremely uncommon and typically only occurs in people receiving long-term intravenous nutrition without proper mineral supplementation.

Coding Tips

• •This code is rarely used in clinical practice; verify documentation clearly states molybdenum deficiency before coding, as it may be confused with other mineral deficiencies
• •Often associated with prolonged parenteral nutrition (TPN); consider coding the underlying condition (such as Z79.4 for long-term use of intravenous antibiotics or related codes) as a secondary diagnosis
