Charging for items outside the traditional billing codes.

based on summary article by Orly Avitzur, Neurology Today based ona presentation by health care lawyer Daniel Brown.

New CPT codes for telephone/internet assessment when provided doctor to doctor by a consultant-- codes 99446-99449.  May be used for complex and urgent situations when face to face is not practical.  These are time based only codes and only available to consulting specialist.  MEDICARE DOES NOT PAY FOR THESE CODES, "check with commercial payors about their policies"

EMAIL (CPT code 98969 and 99444) and phone calls from patients (98966-98968 or 99441-99443) for after hours requests for routine refills of Rx and other requests.  Medicare does not cover these, because they are considered to be included in face to face.  With proper documentation, though you can add time of phone call to the time of the next visit IF its associated with the patient's next visit.  You can factor phone call into the time/complexity calculation of next visit.  Remember that using time , fifty percent of time must be face to face.   If a patient calls several moths after an appointment for an unrelated question, that could be considered a separate service.

Can doctor bill the patient directly for internet consults?  Answer is yes, but CMS "strongly encourages " and advanced beneficiary notice (ABN) before billing so patients can make an informed decision.  Also, MD must not duplicate a service performed at a subsequent visit, the components follow the descriptions in CPT code, and the services are adequately documented.

Bill for forms?  OK to bill for copying, filling forms for camp, or work UNLESS its part of that outpatient visit. 


Concise of brain antigens commonly tested

1.  NMDAR NR1  anti NMDAR encephalitis

2.  amphiphysin-- stiff person syndrome, encephalomyelitis,limbic encephalomyelitis, sensorimotor neuropathy

3.  ARHGAP 25, GRAF -- subacute inflammatory cerebellar ataxia

4. CASPR2 (contactin associated protein 2)-  Morvan syndrome, neuromyotonia, limbic encephalitis


6.  GAD 65-- stiff person syndrome, cerebellar syndrome, limbic encephalitis, epilepsy

7.  Ma2--  brainstem encephalitis, limbic encephalitis, cerebellar syndrome, polyneuropathy

8.  Yo-  brainstem encephalitis, cerebellar syndrome

9.  Ma1 -  brainstem encephalitis, limbic encephalitis, cerebellar syndrome, polyneuropathy

German study published in Ann Neurol July 23 show equal prevalence of these antibodies in healthy and diseased individuals.  Titers and Ig class distribution also were similar for above antigens.

NMDAR were found in 10-20 percent of normal individuals, and are higher among those who suffered influenza.

Hydroxyurea and HbF in sickle cell disease

Steinberg MH et al. Effect of hydroxyurea on mortality and morbidity in adult sickle cell anemia.    Risks and benefits up to 9 years of treatment. JAMA 1003; 289: 1645-51.  Weiner DL, et al. editorial: hydroxyurea and sickle cell disease. A chance for every patient.

HbF is inversely related to mortality in SCD, and can be increased with hydroxyurea.  Also cite Multicenter Study of hydroxyurea (MSH) in SCA (NEJM 1995; 332: 1317-1322).

299 SCA patients were randomized to hydroxyurea or placebo, morbidity was reduced by half, with no difference in mortality or stroke.  There was an open label extension of the trial on 233 patients (both arms) receiving hydroxyurea for 9 years (up to).  In this part of the study, mortality was reduced forty percent for patients receiving hydroxyurea (patient option to take or not).  Cumulative mortality corresponded with HBF levels esp .5 g/dL or higher. 

Machado Joseph disease

aka MJD, spinocerebellar ataxia type 3


adult onset, autosomal dominant
UMN and LMN signs resembling ALS may include tongue fasciculations, dystonia, rigidity, progressive external opthalmoplegia, and peripheral neuropathy.

Due to CAG triplicate repeat on chromosome 14q32.1

Cramping is far more common than in PN or SMA but not ALS and is relieved almost completely by mexilitene, supporting notion that is due to sodium conductance.

Cocaine related hallunications

Classically is the sensation of animal, bugs or insects moving under the skin (cocaine bugs or parasitosis). Other purely visual hallucinations that can occur include "snow lights" or the sensation of sunlight reflecting off snow crystals. Vibrating and pulsating geometric shapes, polyopia, and dysmorphia occur and resemble visual aura. Olfactory, tactile and gustatory hallucinations may occur. Photophobia, halos around lights, and gtrouble focusing may be due instead to pupillary mydriasis due to increased sympathetic tone.

Parkinsonism in cirrhotics

Burkhard PR et al. Arch Neurol 2003;60:521-528


Authors studied cirrhotics prospectively and found a unique Parkinsonian syndrome in 20 %.  Among 51 consecutive patients evaluated for liver transplant, 11 had Parkinsonism esp. stereotypical onset with generalized bradykinesia, dysarthira, postural instability, and prominent ACTION tremor.  Six had dystonia especially of face or feet.  Frontal findings were seen on neuropsych testing.  Levodopa resulted in improvement on UPDRS in 2 patietns.  CSF manganese was elevated in 3 patients in whom it was measured.  Allpatients had symmetric T1 abnormalities on MRI.  Liver transplantation reverses MRI findings.  Question arises of whether to chelate.
