Pregnancy related peripheral neuritis, unspecified trimester

This code describes nerve inflammation or damage in the peripheral nervous system, occurring specifically due to pregnancy. It encompasses conditions like carpal tunnel syndrome, meralgia paresthetica, or other neuropathies that arise during gestation. The "unspecified trimester" indicates that the exact timing within the pregnancy is not documented.

Use this code when a pregnant patient presents with symptoms of peripheral neuropathy, such as numbness, tingling, weakness, or pain in the extremities, and the physician explicitly links the condition to the pregnancy. Documentation should clearly state "pregnancy-related peripheral neuritis" or a similar phrase, without specifying the trimester.

• Always sequence an obstetric code (from category O09-O9A) as the primary diagnosis when applicable.
• Avoid using this code if the peripheral neuritis is pre-existing or clearly unrelated to the pregnancy; consider codes from G50-G59.
• If the specific trimester is documented, use the more specific codes O26.821, O26.822, or O26.823.
