Immersion hand, unspecified hand, sequela

This code signifies a long-term complication or late effect resulting from an immersion injury to an unspecified hand. It indicates that the acute phase of the injury has passed, and the patient is now experiencing residual issues directly attributable to the original immersion event.

Use this code when documenting follow-up care for a patient who previously sustained an immersion injury to a hand, and is now presenting with chronic pain, stiffness, limited range of motion, or other persistent sequelae. This applies when the specific hand (left or right) is not documented or is unknown.

• Always sequence this code after the code for the specific nature of the sequela (e.g., chronic pain, scar formation).
• Ensure the medical record clearly links the current condition to a past immersion injury.
• Avoid using this code for acute immersion injuries; those require codes from the T20-T32 range.
