What is coded for the dose per fraction in a treatment plan where a patient received 45 Gy in 25 fractions?

In a treatment plan, the dose per fraction is calculated by dividing the total dose by the number of fractions. In this scenario, the total dose is 45 Gy, and it is administered over 25 fractions.

To find the dose per fraction, you divide 45 Gy by 25, which results in 1.8 Gy per fraction. When coding this value, it is necessary to express it in a standard numerical format that aligns with the conventions used in medical coding.

In this case, the correct way to represent 1.8 Gy in a normalized code format is to show it as 00180, which indicates that the value is 1.80 expressed as an integer. The format often involves maintaining a specific number of digits, accommodating for leading zeros to ensure consistency in data entry and retrieval.

This coding standard ensures that data can be uniformly understood and processed across different systems and is crucial for effective data management within oncology treatment planning.
