Toxic effect of contact with stingray, undetermined, sequela

This code signifies a long-term or late-appearing health problem resulting from exposure to a stingray's venom, where the intent of the exposure (accidental, intentional self-harm, assault) cannot be determined. It indicates that the initial acute effects of the sting have passed, and the patient is now experiencing a residual condition.

Use this code when documenting a chronic or residual condition directly attributable to a stingray encounter, and the circumstances surrounding the sting are unknown or unspecifiable. This would apply to follow-up visits for conditions like persistent pain, nerve damage, or chronic wounds that developed after the initial sting.

• Requires a seventh character 'S' to denote sequela, indicating a late effect.
• Do not use for acute stingray envenomation; refer to acute toxic effect codes.
• Always code the specific sequela (e.g., chronic pain, scar) first, followed by this code as a secondary diagnosis.
