Endo, nutritional and metab diseases comp preg, unsp tri

This code signifies a maternal condition where pre-existing or gestational endocrine, nutritional, or metabolic disorders adversely affect the pregnancy, without specifying the trimester. It covers a broad range of conditions such as thyroid disorders, diabetes (not otherwise specified as gestational or pre-existing), obesity, or nutritional deficiencies that complicate the pregnancy.

Use this code when documentation indicates an endocrine, nutritional, or metabolic disease is complicating the pregnancy, but the specific trimester is not recorded. This is appropriate when the physician's notes clearly link the maternal condition to the pregnancy's management or outcome, and a more specific code for the condition or trimester is unavailable.

• Always attempt to identify the specific endocrine, nutritional, or metabolic condition and the trimester for more precise coding.
• This code should be sequenced as a secondary diagnosis, with a code from Chapter 15 (O00-O9A) as the primary diagnosis.
• Avoid using this code if a more specific code exists for the documented condition (e.g., O24.4- for gestational diabetes).
