Sequelae of vitamin C deficiency

This code represents the long-term or residual effects resulting from a past vitamin C deficiency (scurvy). These sequelae are not the active deficiency itself, but rather the lasting health problems that persist after the acute phase of scurvy has resolved. Examples include persistent joint pain, dental issues, or bone deformities.

Use this code when a patient presents with a chronic condition directly attributable to a historical episode of vitamin C deficiency. Documentation should clearly link the current manifestation to a prior diagnosis of scurvy, indicating that the active deficiency is no longer present. This code is appropriate for conditions like healed but deformed bones or chronic gingival issues stemming from past scurvy.

• Do not use this code for active vitamin C deficiency; refer to E54 for current scurvy.
• Always code the specific sequela first, if known (e.g., M25.5 for joint pain), followed by this code to indicate its etiology.
• Ensure documentation explicitly states the link between the current condition and a resolved vitamin C deficiency.
