DETERMINING PRIMARY DIAGNOSIS: The logic for determining the primary (first listed) diagnosis remains unchanged. CMS definition The principal diagnosis is the diagnosis most related to the current plan of treatment. It may or may not be related to the patient s most recent hospital stay, but must relate to the services the home health agency rendered. If more than one diagnosis is treated concurrently, enter the diagnosis that represents the most acute condition and requires the most intensive services. Skilled services (SN, PT, OT and SP) only. DETERMINING PRIMARY DIAGNOSIS: The assessing clinician has to determine the primary and secondary diagnoses and symptom control rating, after completing the OASIS Assessment Why am I seeing this patient? What is the primary focus of skilled services? Are there co-morbidities that may impact the POC? Do not consider the number of visits per discipline as a basis for your decision! Determining Primary/Secondary Diagnoses: INCLUDE those conditions actively addressed as well as any co-morbidities affecting the patient s response to treatment EXCLUDE diagnoses that no longer pertain to the plan of care, i.e., hip fracture, appendicitis, gangrene, etc. 2

Co-Morbidity Information: There are some co-morbidities that should always be coded because they are impacted or they may impact the care. CMS states that any co-morbidity affecting the patient s responsiveness to treatment and rehabilitative prognosis, even if the condition is not the focus of any home health treatment itself, should be listed. ALWAYS CODE THESE CO-MORBIDITIES Diabetes HTN COPD CHF CAD Status Sausamputation pua PVD Blindness Chronic diseases, such as Parkinson s History of malignant neoplasm when care is directed at a current neoplasm or otherwise impacts the care Co-Morbidity Information Plan of Care should reflect all diagnoses including co-morbidities #21 SN to assess diabetes and HTN for potential impact on plan of care #22 Patient will have no complications related to diabetes and HTN this episode If therapy only, co-morbidities must also be addressed in therapy Plan of Care PT to check blood pressure every visit and report to physician if >185/95 and/or < 90/60 Patient s blood pressure will remain within parameters this episode 3

Primary/Secondary Diagnoses DO NOT automatically code something without physician documentation ti or communication with the physician documented, i.e., urinary retention or neurogenic bladder Guidance from Official Coding Guidelines A joint effort between the healthcare provider and the coder is essential to achieve complete and accurate documentation, code assignment, and reporting of diagnoses and procedures. In the context of these guidelines, the term provider is used throughout the guidelines to mean physician or any qualified health care practitioner who is legally accountable for establishing the patient s diagnosis. Guidance from Medicare CoP 484.18(a) Standard: Plan of Care If a physician refers a patient under a plan of care that cannot be completed until after an evaluation visit, the physician is consulted to approve additions or modification to the original plan. 4

Guidance from OASIS Manual Agencies should avoid listing diagnoses that are of mere historical interest and without impact on the patient progress or outcome. (OASIS-C Guidance Manual Chapter 3 Item Intent C-9) Coding Impact on Reimbursement Payment based on an HHRG (Home Health Resource Group) OASIS items M0110 and M2200 determine payment equation 20 additional OASIS items determine Clinical severity score Functional severity score Service Utilization severity score ICD-9-CM codes are part of the clinical severity score Coding Impact on Reimbursement Clinical Domain 22 Diagnostic Categories 1 - Blindness & Low Vision 12 - Neuro 3 (Stroke) 2 - Blood Disorders 13 - Neuro 4 (MS) 3 - Cancers & Neoplasms 14 - Ortho 1 (Leg) 4 - Diabetes 15 - Ortho 2 (Other) 5 - Dysphagia 16 - Psych 1 (Affective) 6 - Gait Abnormality 17 - Psych 2 (Degenerative) 7 - Gastrointestinal Disorder 18 - Pulmonary 8 - Heart Disease 19 - Skin 1 (Trauma & Burns) 9 - Hypertension 20 - Skin 2 (Ulcers & Other) 10 - Neuro 1 (Brain) 21 - Tracheostomy Care 11 - Neuro 2 (Peripheral) 22 - Urostomy/Cystostomy Care 5

(M1020/1022/1024) Diagnoses, Symptom Control, and Payment Diagnoses: List each diagnosis for which the patient is receiving home care (Column 1) and enter its ICD-9-C M code at the level of highest specificity (no surgical/procedure codes) (Column 2). Diagnoses are listed in the order that best reflect the seriousness of each condition and support the disciplines and services provided. Rate the degree of symptom control for each condition (Column 2). Choose one value that represents the degree of symptom control appropriate for each diagnosis: V-codes (for M1020 or M1022) or E-codes (for M1022 only) may be used. ICD-9-C M sequencing requirements must be followed if multiple coding is indicated for any diagnoses. If a V-code is reported in place of a case mix diagnosis, then optional item M1024 Payment Diagnoses (Columns 3 and 4) may be completed. A case mix diagnosis is a diagnosis that determines the Medicare P P S case mix group. Do not assign symptom ratings for V- or E- codes. Code each row according to the following directions for each column: Column 1: Enter the description of the diagnosis. Column 2: Enter the ICD-9-C M code for the diagnosis described in Column 1; Rate the degree of symptom control for the condition listed in Column 1 using the following scale: 0 - Asymptomatic, no treatment needed at this time 1 - Symptoms well controlled with current therapy 2 - Symptoms controlled with difficulty, affecting daily functioning; patient needs ongoing monitoring 3 - Symptoms poorly controlled; patient needs frequent adjustment in treatment and dose monitoring 4 - Symptoms poorly controlled; history of re-hospitalizations Note that in Column 2 the rating for symptom control of each diagnosis should not be used to determine the sequencing of the diagnoses listed in Column 1. These are separate items and sequencing may not coincide. Sequencing of diagnoses should reflect the seriousness of each condition and support the disciplines and services provided. Column 3: (OPTIONAL) If a V-code is assigned to any row in Column 2, in place of a case mix diagnosis, it may be necessary to complete optional item M1024 Payment Diagnoses (Columns 3 and 4). See OASIS-C Guidance Manual.
