Clinical Documentation Tips: Reflection of Acuity & Medical Necessity

1. Clinical Documentation TipsReflection of Acuity & Medical Necessity “I Bill for It”

2. Objectives • Understand the elements of synergies in clinical documentation impacting physicians and hospitals • Understand relationship between specificity in documentation and patient acuity • Learn how patient acuity and comorbid conditions drives medical necessity and E & M assignment • Appreciate the “pitfalls” and “traps” of documentation that contribute to denials and downcoding of E & M

3. History of Present Illness • HPI is chronological description of the development of the patient’s present illness from the first sign and/or symptom or from the previous encounter to the present. • Focus upon present illness!

4. HPI • HPI → 8 elements • Location • Quality • Severity • Duration • Timing • Context • Modifying factors • Associated signs and symptoms

5. HPI that are really “HPI’s” • Mrs. Jones, a 75 year old patient presented to the Emergency Room with abdominal pain lower left quadrant of three days duration, suddenly worse last night, with associated shortness of breath, took Maalox, didn’t help. Pain described as at 10 on a pains scale of 10. Pain now 7 out of 10 after receiving Morphine in the ER.

6. Right to the Point NO Fluff

7. Right to the Point • HPI- The patient presented from the Personal Care Home with a two day history of worsening shortness of breath and nonproductive cough. She started using oxygen at home but this got progressively worse , particularly when ambulating, and she came to the Emergency Room this morning and was found to be in acute respiratory distress.

8. Right to the Point • She was evaluated and found to have acute hypoxemic respiratory failure, congestive heart failure with possible pneumonia. She was stabilized somewhat in the Emergency Room but is still short of breath, more so that at her usual baseline. She is being admitted for further evaluation and treatment.

9. Assessment & Plan • This is a 75 year old-female with 1) Acute congestive heart failure, acute left ventricular systolic dysfunction with probable chronic left ventricular systolic dysfunction. We are going to admit her, give her fluid restrictions, intravenous Lasix for diuresis and pulmonary toilet. Will monitor closely.

10. Assessment & Plan • 1) Chronic obstructive pulmonary disease exacerbation with acute on chronic respiratory failure and hypoxia and hypercapnia and acute respiratory acidosis. We are going to give her oxygen and pulmonary toilet with Duoneb treatment. Will diurese her as noted above. Will cover empirically for infection with Avelox, 400 mg, IV daily. Monitor closely and call in pulmonology service and cardiology service if clinical conditions worsen.

11. Assessment & Plan Continued • 3) Diabetes mellitus, Type II controlled, and will continue her on Lantus and start her regular insulin sliding scale and monitor • 4) Hypertension, will continue current medications and monitor • History of breast cancer. Status post lumpectomy, apparently stable. • 5) History of long QT syndrome. She does have an implantable defibrillator. Will rule out MI per protocol and monitor closely • (Total time for H & P examination one hour)

12. The Driver

13. Role of HPI • HPI drivers: • Extent of PFSH, ROS and physical exam performed • Medical necessity for amount work performed and documented • Medical necessity for E & M assignment • Medical necessity of an Evaluation and Management (E/M) encounter is often visualized only when viewed through the prism of its characteristics captured in specific History of Present Illness (HPI) elements.

14. Speaking of Medical Necessity • Federal law requires that all expenses paid by Medicare, including expenses for Evaluation and Management services, are medically reasonable and necessary. • 1862(a)(1)(a) of the Social Security Act, Title XVIII • No payment can be made for items and services that are not reasonable and necessary for the diagnosis or treatment of illness or injury or to improve the functioning of a malformed body member. • Applies to physician and hospital

15. Synergy of Clinical Documentation • Physician Responsible for patient designation assignment • Inpatient versus Outpatient Service • The decision to admit a patient is a complex medical judgment which can be made only after the physician has considered a number of factors, including the patient's medical history and current medical needs, the types of facilities available to inpatients and to outpatients, the hospital's by-laws and admissions policies, and the relative appropriateness of treatment in each setting.

16. Documentation of Acuity • Factors to be considered when making the decision to admit include such things as: • The severity of the signs and symptoms exhibited by the patient; • The medical predictability of something adverse happening to the patient; • The need for diagnostic studies that appropriately are outpatient services (i.e., their performance does not ordinarily require the patient to remain at the hospital for 24 hours or more) to assist in assessing whether the patient should be admitted; and • The availability of diagnostic procedures at the time when and at the location where the patient presents.

17. Business Synergy

18. Medical Necessity • Medical necessity of a service is the overarching criterion for payment in addition to the individual requirements of a CPT code. • It would not be medically necessary or appropriate to bill a higher level of evaluation and management service when a lower level of service is warranted. • Less Complex diagnoses potentially warrant a lower level of E & M

19. Medical Complexity Signs, Symptoms & Nonspecific Diagnoses Specific Diagnoses • Chest Pain/Acute Coronary Syndrome • Hypoxemia/Acute Respiratory Distress • Nausea and Vomiting • CHF • Postobstructive Pneumonia with right lower lobe cancer inoperable • Non ST MI with unstable angina • Acute hypoxemic respiratory failure • Food poisoning with severe dehydration • Acute on chronic systolic left sided heart failure • Suspected gram-negative pneumonia in a patient with known inoperable RLL cancer

20. Medical Necessity • Medical necessity of E/M services is generally expressed in two ways: frequency of services and intensity of service (CPT level). • Medicare’s determination of medical necessity is separate from its determination that the E/M service was rendered as billed.

21. Medical Necessity • Medicare determines medical necessity largely through the experience and judgment of clinician coders along with the limited tools provided in CPT and by CMS. • At audit, Medicare will deny or downcode E/M services that, in its judgment, exceed the patient’s documented needs

22. Elements of Medical Necessity • Medical necessity of E/M services is based on the following attributes of the service that affected the physician’s documented work: • Number, acuity and severity/duration of diagnoses/ problems addressed through history, physical and medical decision-making.

23. Common Documentation Deficiency • Progress Note • 9/13 10:10 AM- Patient had no new complaints, stable overnight. VS stable, Labs WNL. • Assessment and Plan: Continue Present Management • Deficiency • Not Clear Face-to-Face Encounter • Absence of Diagnoses • No Billable E & M service

24. Elements of Medical Necessity • The context of the encounter among all other services previously rendered for the same problem • Complexity of documented comorbidities that clearly influenced physician work. • Physical scope encompassed by the problems (number of physical systems affected by the problems).

25. Complexity Does Matter Less Complex More Complex • Acute respiratory distress • CHF • CHF worsening • COPD exacerbation • COPD exacerbation with hypoxemia • Acute respiratory failure • Acute systolic CHF • Acute on chronic systolic CHF • Acute respiratory failure with COPD exac • COPD exacerbation with chronic respiratory failure

26. Complexity Does Matter Less Complex More Complex • Acute renal insufficiency • Chronic hypoxemia • Cardiac arrhythmia • Acute renal failure • Chronic renal failure • Hypoalbuminemia • Acute renal failure • Chronic respiratory failure • Atrial fibrillation • Acute tubular necrosis/acute interstitial nephritis • Chronic renal failure stage IV • Protein calorie malnutrition

27. Medical Decision Making

28. Decision Point

29. Medical Decision Making • Medical decision making refers to the complexity of establishing a diagnosis and/or selecting a management option as measured by: • The number of possible diagnoses and/or the number of management options that must be considered; • The amount and/or complexity of medical records, diagnostic tests, and/or other information that must be obtained, reviewed, and analyzed; and • The risk of significant complications, morbidity, and/or mortality, as well as comorbidities associated with the patient's presenting problem(s), the diagnostic procedure(s) and/or the possible management options.

30. Medical Decision Making • MDM consists of 4 levels • Straight Forward Complexity • Low Complexity • Moderate Complexity • High Complexity • General Rule of Thumb is inpatient encounter should equate to Moderate or High Complexity

31. Amount & Complexity of Data • The amount and complexity of data to be reviewed is based on the types of diagnostic testing ordered or reviewed. • A decision to obtain and review old medical records and/or obtain history from sources other than the patient increases the amount and complexity of data to be reviewed

32. Number of Diagnoses & Management Options • The number of possible diagnoses and/or the number of management options that must be considered is based on the number and types of problems addressed during the encounter, the complexity of establishing a diagnosis and the management decisions that are made by the physician.

33. Documentation Tips • DG: For each encounter, an assessment, clinical impression, or diagnosis should (must)be documented. It may be explicitly stated or implied in documented decisions regarding management plans and/or further evaluation. • For a presenting problem with an established diagnosis the record should reflect whether the problem is: a) improved, well controlled, resolving or resolved; or, b) inadequately controlled, worsening, or failing to change as expected.

34. Documentation Tips • For a presenting problem without an established diagnosis, the assessment or clinical impression may be stated in the form of a differential diagnoses or as "possible,” "probable,” or "rule out” (R/O) diagnoses.

35. Best Strategy Documentation • Chief Complaint: Chest Pain • HPI- Eighty-five year old female patient unassigned presented to the ER with abdominal pain 8 out 10 radiating to the chest, associated shortness of breath, worse at night and after eating a large meal. Patient states pain was waxing and waning for last few days, became intolerable this morning, not relieved by Maalox, prompted her to seek medical attention in the Emergency Room.

36. Best Strategy Documentation • Assessment & Plan • Chest pain- possible MI but less likely given the fact the patient does not have any risk factors for MI other than age. Will still initiate the ROMI protocol to ensure we don’t get caught in situation of blind obedience • Abdominal pain- likely mesenteric ischemia in light of the fact patient’s abdominal pain is worse after eating a large meal. Will order mesenteric duplex ultrasound and CT scan with contrast to evaluate status of vasculature. Will consult surgery for their recommendations of further work-up. IV pain meds as needed and NPO for now.

37. Practical Documentation Tips • When documenting MDM, a list of established diagnoses or potential diagnoses is insufficient for coding purposes without additional indications in the record of meaningful and necessary evaluation for each problem. • Practitioners should record relevant impressions, tentative diagnoses, confirmed diagnoses and all therapeutic options chosen related to every problem for which evaluation and management is clearly demonstrated • Tip- stability of chronic conditions should be documented as well as discussion of relationship to abnormal diagnostic results to established or provisional diagnoses.

38. Documentation Approach Tell Documentation Show Documentation • Assessment: • Dizziness and headache • TIA- • Acute sinusitis • Hypertension • Hyperlipidemia • Gout • History of breast cancer • Assessment: • Dizziness and headache • TIA- with patient describing an episode of slurred speech and difficulty finding words and weakness of left arm, this may be a TIA, will order a follow-up CT as initial in ER was indeterminate. • Hypertension- BP reading in the ER indicated hypertensive urgency, 205/120, perhaps BP elevation contributing to patient’s dizziness and headache. Will monitor and step up her anti-hypertension meds

39. Clinical Case Study • HPI: Mrs. Cold Weather presented to the Emergency Room with shortness of breath of three days duration, complains of chest pain at the same time of shortness of breath, waxing and waning, stabbing at some time, 8 out of 10, not relieved by her usual nitro. • PFH: Ischemic cardiomyopathy, hypertension, EF 10-15%

40. Clinical Case Study Continued…. • PSH: quite smoking 20 years ago, lives with her husband who is in good health for his age • Past Surgical History; Non-contributory • Labs: BNP 2276, cardiac enzymes and Troponin mildly elevated • Chest X-ray shows cardiomegaly with pulmonary vascular congestion

41. Clinical Case Study Continued…. • Clinical Impression: • Chest pain and shortness of breath rule out MI, rule out MI protocol • Elevated BNP- will start IV Lasix IV 80 mg, monitor output, chest X-ray PM, • Reduced EF- left ventricular systolic dysfunction • Chronic renal insufficiency

42. Take Two

43. Clinical Case Study Continued…. • Clinical Impression: Mrs. Cold Weather with history of ischemic cardiomyopathy and end stage renal disease presents with chest pain and shortness of breath • Possible MI, will follow MI protocol • Possible Acute systolic CHF, likely chronic in nature also, continue to diurese. Will contact patient’s regular cardiologist • End stage renal disease- will need monitor renal function closely and diurese carefully

44. Table of Risk • The risk of significant complications, morbidity, and/or mortality is based on the risks associated with the presenting problem(s), the diagnostic procedure(s), and the possible management options. • DG: Comorbidities/underlying diseases or other factors that increase the complexity of medical decision making by increasing the risk of complications, morbidity, and/or mortality should be documented.
