Anesthesia complicated by the use of controlled hypotension; this add-on code is used with a primary anesthesia procedure code.
Modifiers 59 (Distinct Procedural Service) or others may be applicable depending on the circumstances of the anesthesia services rendered.Consult the CPT manual for appropriate modifier use.
Medical necessity for code 99135 is established when controlled hypotension is required to improve surgical visualization and reduce bleeding during a procedure, thereby improving surgical outcome. The specific procedure must justify the need for this technique.
The anesthesia provider is responsible for inducing and maintaining controlled hypotension, continuously monitoring the patient's blood pressure, and documenting these actions.
In simple words: This code is for when a doctor uses special medicine during surgery to lower the patient's blood pressure.This helps the surgeon see better and reduces bleeding, but it makes giving anesthesia more complex. This code is added to the main anesthesia code, not used alone.
This CPT code, 99135, reports anesthesia complicated by the utilization of controlled hypotension.It's an add-on code, meaning it must be reported in addition to the primary anesthesia procedure code.Controlled hypotension is the deliberate reduction of a patient's blood pressure during surgery to improve surgical visualization and reduce bleeding.The anesthesia provider must induce and monitor the controlled hypotension throughout the procedure. Proper documentation of the induction and monitoring of controlled hypotension is crucial for reimbursement.
Example 1: A patient undergoes a complex neurosurgical procedure.Controlled hypotension is induced to minimize bleeding in the delicate brain region, improving surgical precision.Code 99135 is added to the primary anesthesia code., During an orthopedic surgery involving significant vascularity, controlled hypotension is used to reduce blood loss and improve visibility. The anesthesia provider carefully monitors the patient's blood pressure and documents the use of controlled hypotension. Code 99135 is appended to the primary anesthesia code., A patient requires head and neck surgery with a high risk of significant bleeding. Controlled hypotension is employed to minimize blood loss, optimizing the surgical field. The anesthesia professional meticulously monitors vital signs and documents the procedure. Code 99135 is added to the main anesthesia code.
* Comprehensive anesthesia record* Detailed documentation of the induction and maintenance of controlled hypotension* Continuous blood pressure monitoring data throughout the procedure* Specific medications used to induce hypotension and their dosages* Any adverse events related to controlled hypotension and interventions taken.
** Payers may have specific requirements for documentation and reimbursement. Always refer to the payer's guidelines.This code reflects a complex anesthesia management technique that requires careful documentation for successful claim processing.
