Pregnancy related peripheral neuritis, second trimester

This code identifies the occurrence of peripheral nerve inflammation or damage, such as carpal tunnel syndrome or meralgia paresthetica, that develops specifically due to pregnancy. It indicates that the condition manifested or was diagnosed during the second trimester of gestation.

Apply this code when documentation clearly states a diagnosis of peripheral neuritis directly attributed to the pregnant state, with the onset or diagnosis occurring between the 14th and 27th week of gestation. Supporting documentation would include physician notes detailing symptoms, diagnostic findings, and the gestational age at diagnosis.

• Ensure the documentation explicitly links the neuritis to the pregnancy and specifies the second trimester.
• Do not use for pre-existing peripheral neuropathies exacerbated by pregnancy; those would typically be coded with a chapter 6 code (G00-G99) and a secondary pregnancy code.
• Sequence this code as the primary diagnosis if it is the main reason for the encounter; otherwise, it would be a secondary diagnosis.
