Heat exposure on board fishing boat, subsequent encounter

This code signifies a patient presenting for follow-up care or complications related to a previous heat exposure incident that occurred while they were on a fishing boat. It indicates that the initial injury or condition from the heat exposure has already been addressed, and the current encounter is for ongoing management.

Use this code for patients returning for treatment of lingering effects of heat stroke, heat exhaustion, or heat cramps sustained on a fishing vessel. This includes appointments for monitoring recovery, managing secondary complications, or addressing persistent symptoms after the initial acute phase.

• Requires a seventh character "D" for subsequent encounter.
• Always sequence this code after the primary diagnosis describing the specific heat-related illness (e.g., T67.0XXD for heatstroke).
• Ensure documentation clearly states the patient is returning for follow-up care related to the initial heat exposure.
