Spinal and epidur anesth induce hdache dur preg, first tri

This code describes a headache experienced by a pregnant patient during her first trimester, specifically caused by spinal or epidural anesthesia. This type of headache is a known complication of neuraxial anesthesia, often resulting from a dural puncture and subsequent cerebrospinal fluid leakage.

Apply this code when documentation clearly links a headache in a first-trimester pregnant patient to recent spinal or epidural anesthesia. This typically occurs post-procedure, such as after an epidural for pain management or spinal anesthesia for a surgical procedure during early pregnancy. The provider's notes should explicitly state the causal relationship.

• Ensure the documentation specifies "first trimester" for accurate trimester assignment.
• Do not use this code for headaches unrelated to anesthesia or for headaches occurring in later trimesters.
• Code the specific type of headache (e.g., postdural puncture headache) if further detail is provided and a more specific code exists.
