Nail entering through skin, sequela

This code describes the long-term effects or complications resulting from a nail having penetrated the skin. This could include chronic pain, scarring, infection, or functional impairment that persists after the initial injury has healed. It indicates that the original injury is no longer acute but has left a lasting sequela.

Use this code when documenting a patient presenting with a current condition directly attributable to a past injury where a nail entered the skin. This is appropriate for follow-up encounters addressing chronic issues stemming from the original penetration, such as a non-healing wound, persistent nerve damage, or a foreign body granuloma related to the nail entry.

• Always use in conjunction with a code describing the specific sequela (e.g., chronic pain, scar, infection).
• Ensure documentation clearly links the current condition to the past nail penetration.
• Do not use for the initial acute injury; this code is exclusively for sequelae.
