Review of systems. A review of systems (ROS) is a series of questions inquiring about additional signs, symptoms, or problems currently or previously experienced by the patient as related to the CC or presenting problem. The recognized systems are constitutional; eyes; ears, nose, mouth, throat; cardiovascular; respiratory; gastrointestinal; genitourinary; musculoskeletal; integumentary (including skin and/or breast); neurological; psychiatric; endocrine; hematologic/lymphatic; and allergic/immunologic.2,3
The physician may choose to document the ROS by making a notation for individual systems: “no fever/chills (constitutional) or blurred vision (eyes); no chest pain (cardiovascular) or shortness of breath (respiratory); intermittent nausea (gastrointestinal) and occasional runny nose (ears, nose, mouth, throat).” Alternatively, the physician may inquire about all of the systems but only document the positive and pertinent negative findings related to the CC, along with an additional comment that “all other systems are negative.” Most Medicare audit contractors currently accept this method as long as all systems were reviewed.5,6,7,8,9
Be advised that ROS information can be documented by anyone, including the patient. The physician must remember to reference ROS information that is completed by individuals other than residents or nonphysician practitioners (the physician is already required to reference the documentation of the latter individuals under the Teaching Physician Rules or Split-Shared Billing Rules).
Past, family, and social histories. Documentation of past, family, and social histories (PFSH) involves data obtained about the patient’s previous illness or medical conditions/therapies, family occurrences with illness, and relevant patient activities. An auditor credits the physician for a single comment correlated to each history for the PFSH. Using the term “noncontributory” (N/C) with any of the histories can result in downcoding. Many contractors do not allow this statement due to previous misunderstandings over its use.
- Incomplete PFSH example: “Patient is status-post cholecystectomy in August 2013; family history N/C; patient is former smoker” (Note: “family history N/C” is not accepted by most contractors).
- Better PFSH example: “Patient currently on Prilosec 20 mg daily; family history of Barrett’s Esophagus; no tobacco or alcohol use.”
PFSH data can also be documented by anyone, including the patient, and the physician must reference the PFSH information in his own progress note. Re-documenting the PFSH is not necessary unless a revision is required. PFSH documentation is only required for initial care services (i.e., initial hospital care, initial observation care, consultations). It is not required for subsequent care services, unless additional pertinent information that impacts care is obtained during the hospital stay.
Common Problems to Avoid
Information cannot be obtained. Some contractors will not penalize the physician for the inability to ascertain complete historical information as long as there is evidenced documentation of an attempt to obtain the information. When the physician cannot extract historical information from the patient directly and no other source is available, the physician documents that he is “unable to obtain” the history. Additionally, the physician must provide a comment to explain why the information is unobtainable (e.g. patient confused, no caregiver present) along with the available information from the limited resources (e.g. emergency medical technicians, records from previous hospitalizations at the same facility).
Previous information referenced. When referencing items from a previous encounter, be sure to include the referenced information when documentation is requested by the payer. Per CMS guidelines, the ROS and/or PFSH obtained during an earlier encounter does not need to be re-recorded if there is evidence that the physician reviewed and updated the previous information. The review and update may be documented by either describing any new ROS and/or PFSH information or noting that there has been no change in the information and noting the date and location of the earlier ROS and/or PFSH.2
