Botulinum Toxin Injections

Botulinum toxins are potent neuromuscular blocking agents that are useful in treating various focal muscle spastic disorders and excessive muscle contractions, such as dystonia, spasms, and twitches. They produce a presynaptic neuromuscular blockade by preventing the release of acetylcholine from the nerve endings. Since the resulting chemical denervation of muscle produces local paresis or paralysis, selected muscles can be treated. Botulinum toxins are used in the treatment of overactive skeletal muscles, smooth muscles and glands.

Documentation Requirements

Documentation recommended for the support of botulinum toxin injections includes:

  • A covered diagnosis
  • Dosage and frequency of planned injections

  • Documentation to support the medical necessity when electromyography procedures performed in conjunction with botulinum toxin type A injections to determine the proper injection site(s) (when applicable)
  • To support continuous treatment, the documentation should include the clinical effectiveness of two consecutive treatments that preceded the anticipated procedure (refer to your MAC’s LCD/LCA)
  • Documentation of the management of a chronic migraine diagnosis. A medical record must include a history of migraine and experiencing frequent headaches on most days of the month

If botulinum toxin is being used to treat chronic migraines, documentation should support that headache occurred greater than 15 days in one month and that eight of the headaches were migraines. Evidence of conservative treatment tried and proven unsuccessful should be documented.

Continuous treatment of botulinum toxin will be considered medically reasonable and necessary when the following are supported in the documentation:

  • Injections have been administered approximately 12 weeks apart.
  • Injection sites that correlate to the administration CPT code and treatment diagnosis. If the internal protocol is not well known, please include an injection site map to support the requested code(s).
