2025 CPT code 00811

Anesthesia services for lower intestinal endoscopic procedures where the endoscope is inserted distally to the duodenum.

Adhere to the most up-to-date CPT and payer-specific guidelines for anesthesia coding.Documentation must clearly support the medical necessity of anesthesia and the level of service provided.Modifiers may be necessary depending on the circumstances of the procedure and the payer's requirements.

Modifiers may be applied to this code depending on the circumstances of the procedure (e.g., repeat procedure, unusual anesthesia).Refer to the current CPT guidelines and payer-specific instructions for appropriate modifier usage.

Medical necessity is established based on the patient's clinical presentation and the need for anesthesia to ensure patient safety and comfort during a lower intestinal endoscopic procedure. The level of anesthesia provided should be appropriate for the patient's medical condition and the anticipated complexity of the procedure.Payers may require additional documentation supporting the need for anesthesia for certain patients, especially those at lower risk.

The anesthesiologist is responsible for pre-operative evaluation, induction and maintenance of anesthesia, monitoring vital signs, administering medications, and post-operative care until transfer to post-anesthesia care.

IMPORTANT May be used in conjunction with other anesthesia codes depending on the complexity of the procedure.Code 00812 is used specifically for screening colonoscopies; code 00813 is used for combined upper and lower GI endoscopy procedures. If the screening colonoscopy converts to a diagnostic procedure (due to biopsy, polypectomy, etc.), code 00811 might be more appropriate according to CMS guidelines.

In simple words: This code covers the doctor's services for keeping a patient asleep and comfortable during a lower intestinal endoscopy (a procedure where a thin, lighted tube is inserted into the lower intestines for examination).This includes the preparation before the procedure, monitoring the patient during the procedure, giving medicine and fluids, and checking the patient’s vital signs afterwards.

This CPT code encompasses anesthesia services rendered during lower intestinal endoscopic procedures.The procedure involves the insertion of an endoscope into the intestines, reaching a point distal to the duodenum (the section of the small intestine immediately below the stomach), but not beyond.The anesthesia provider's responsibilities include pre-operative evaluation, induction and monitoring of anesthesia during the procedure, administration of necessary medications and fluids, standard monitoring (ECG, temperature, blood pressure, oximetry, capnography, and mass spectrometry), and overseeing patient transfer to post-anesthesia care.Unusual monitoring methods (Swan-Ganz catheters, intra-arterial lines, central venous lines) are coded separately if documented.

Example 1: A patient undergoes a colonoscopy for suspected colon polyps. The anesthesiologist administers general anesthesia, monitors vital signs, and administers supplemental oxygen and fluids as needed. Post-procedure, the patient is transferred to PACU., A patient with a history of heart disease undergoes a sigmoidoscopy. The anesthesiologist performs a thorough pre-operative evaluation, carefully monitors the patient's cardiovascular status during the procedure, and adjusts medication and fluids accordingly., A patient with severe anxiety presents for a colonoscopy. The anesthesiologist uses monitored anesthesia care (MAC), providing sedation and close monitoring, adjusting the level of sedation to maintain comfort while allowing the patient to cooperate during the procedure.

Detailed documentation should include the type of anesthesia administered, time of anesthesia administration, medications used and dosages, monitoring parameters and findings (ECG, blood pressure, pulse oximetry, capnography, etc.), any complications, and post-operative course.Pre-operative assessment findings, including relevant comorbidities and patient risk factors, should be well documented.

** Always verify the specific requirements of the payer before submitting claims.Accurate and complete documentation is critical for proper reimbursement. Pay close attention to whether the procedure is a screening or diagnostic colonoscopy, as this will impact coding.
