Question: What is the proper code(s) to report Tensilon tests?
Texas Subscriber
Answer: The proper code is 95857 (Tensilon test for myasthenia gravis) or, if electromyography is performed at the same time, 95858 ( with electromyographic recording).
Tensilon testing is a diagnostic procedure performed in the office or hospital to help differentiate causes of weakness, double vision and drooping eyelids, such as when myasthenia gravis (358.0) is suspected. The physician performs the test by injecting Tensilon (edrophonium chloride) into a vein and comparing the patient's strength before and after administration. Tensilon improves muscle strength by increasing muscular response to nerve impulses. Effects of the drug last about 10 minutes or less. The test is considered positive when there is a definite improvement in the patient's strength.
Generally accepted ICD-9 codes for Tensilon testing include:
368.2 Diplopia
374.30 Ptosis of eyelid, unspecified
378.73 Strabismus in other neuromuscular disorders
728.9 Unspecified disorder of muscle, ligament, and fascia
780.7 Malaise and fatigue
784.5 Other speech disturbance
786.09 Symptoms involving respiratory system and other chest symptoms, other
787.2 Dysphagia.
