Coding in PD can be cumbersome. Time to collect medical history, physical examination and assessment of treatment can vary for each patient.
Here are some guidelines that you can use when addressing this issue:
ICD-9 code: 332 Parkinson’s disease
ICD-9 code: 332.1 Secondary parkinsonism
ICD-9 code: 333 Other extrapyramidal disease and abnormal movement disorders
99201-99205 New patient (not seen by specialists in your practice within 3 years)
99211-99215 Established patient
99354-99359 Prolonged Services (bill level of service then prolonged service for additional time
greater than 30 minutes)
Modifiers Modifier 25–Same day separate procedure (EM visit and procedure with separate
documentation such as DBSi or botulinum injection)
There are two set of guidelines for billing, the 1995 or the 1997 guidelines. You must check with your institution, what set is being used. The following information is based on the 1997 E/M guidelines.
The following components will determine the codes that you can use when billing:
History levels are determined by chief complaint (CC), history of present illness (HPI), review of systems (ROS) and past, family, and/or social history (PFSH).

For purposes of ROS, the following systems are recognized:
• Constitutional symptoms (eg, fever, weight loss) • Eyes
• Ears, Nose, Mouth, Throat • Cardiovascular • Respiratory • Gastrointestinal
• Genitourinary • Musculoskeletal • Integumentary (skin and/or breast) • Neurological
• Psychiatric • Endocrine • Hematologic/Lymphatic • Allergic/Immunologic
Notes:
1997 E/M guidelines require you to document the examination using specific bullets. Document if you are conducting a problem focused examination (1-5 bullets); an expanded problem-focused (6+ bullets); a detailed examination (at least 2 bullets from 6 organ systems OR 12 bullets from 2 or more organ systems); or a comprehensive evaluation (2 bulletsfrom each of nine organ systems). For details on the bullets click here.
These types of examinations have been defined for general multi-system and the following single organ systems:
• Cardiovascular • Ears, Nose, Mouth and Throat • Eyes • Genitourinary (Female)
• Genitourinary (Male) • Hematologic/Lymphatic/Immunologic • Musculoskeletal
• Neurological • Psychiatric • Respiratory • Skin
Medical decision making is divided into four levels: (a) Straight-forward, (b) Low complexity, (c) Moderate complexity, and (d) High complexity. Medical decision making refers to the complexity of establishing a diagnosis and/or selecting a management option as measured by (a) the number of diagnoses or treatment options, (b) the amount or complexity of data to be reviewed and, (c) the risk of complications and/or morbidity/mortality. The following chart shows the progression of the elements for each level of medical decision making. Two of the three elements in the table must be either met or exceeded:
|

Amount and/or complexity of data to be reviewed |
Risk of complications and/or morbidity or mortality |
