Pnctr w/o fb of left thumb w/o damage to nail, sequela

This code describes the long-term effects or complications arising from a past puncture wound to the left thumb, where no foreign object was embedded and the nail was not damaged at the time of the original injury. It indicates a condition or symptom that persists or develops as a consequence of that previous wound.

This code is appropriate when a patient presents with a current condition directly attributable to a puncture wound of the left thumb that occurred in the past, and that original injury did not involve a foreign body or nail damage. Examples include chronic pain, scar tissue complications, or nerve damage that developed after the initial wound healed.

• Requires a seventh character "S" for sequela, indicating a complication or condition resulting from a previous injury.
• Ensure documentation clearly links the current condition to a past puncture wound of the left thumb.
• Do not use for acute or initial encounters of a puncture wound; those would use the A or D seventh characters.
