Pregnancy related peripheral neuritis, first trimester

This code signifies the presence of inflammation or damage to peripheral nerves that is directly attributable to the physiological changes of pregnancy, occurring specifically within the first trimester. Symptoms often include pain, numbness, tingling, or weakness in the extremities. This condition is distinct from pre-existing neurological disorders.

Apply this code when a pregnant patient in her first trimester presents with new-onset peripheral neuropathy symptoms, and the clinician explicitly links the condition to the pregnancy. Documentation should clearly state "pregnancy-related" or "gestational" peripheral neuritis and specify the trimester.

• Ensure the documentation explicitly states "first trimester" to support this specific code.
• Do not use for pre-existing peripheral neuropathies exacerbated by pregnancy; those require codes from Chapter 6 (Diseases of the Nervous System) with an additional pregnancy code.
• Verify the physician's documentation clearly establishes a causal link between the pregnancy and the neuritis, not just a co-occurrence.
