certain conditions, the bone may be affected at the upper or lower end, (e.g., avascular necrosis of bone, M87, Osteoporosis, M80, M81). • Though the portion of the bone affected may be at the joint, the site designation will be the bone, not the joint. jhmci.com 53 Acute traumatic versus chronic or recurrent musculoskeletal conditions 1. Many musculoskeletal conditions are a result of previous injury or trauma to a site, or are recurrent conditions. 2. Bone, joint or muscle conditions that are the result of a healed injury are usually found in chapter 13. 3. Recurrent bone, joint or muscle conditions are also usually found in chapter 13. 4. Any current, acute injury should be coded to the appropriate injury code from chapter 19. 5. Chronic or recurrent conditions should generally be coded with a code from chapter 13. jhmci.com 54 Pathological Fractures • Also known as (AKA): Spontaneous fracture • Fracture reported in addition to underlying condition responsible for fracture • Never assign a code for a traumatic fracture and pathological fracture of same bone • 7th character indicates treatment plans, such as A for initial jhmci.com 55 Coding Note:ICD-10-CM has three ICD-10 Pathological or Stress Fracture Extensions different categories for pathologic fractures – due to neoplastic disease, due to osteoporosis, and due to other specified disease.

other specified disease. jhmci.com 58 Coding of Pathologic Fractures • 7th character A is for use as long as the patient is receiving active treatment for the fracture. • Examples of active treatment are: surgical treatment, emergency department encounter, evaluation and treatment by a new physician. • 7th character, D is to be used for encounters after the patient has completed active treatment. • The other 7th characters, listed under each subcategory in the Tabular List, are to be used for subsequent encounters for treatment of problems associated with the healing, such as malunions, nonunions, and sequelae. • Care for complications of surgical treatment for fracture repairs during the healing or recovery phase should be coded with the appropriate complication codes. jhmci.com 59

fracture, identify the site of the fracture, not the osteoporosis. jhmci.com 62 Osteoporosis • M80 Osteoporosis with current pathological Fx – Systemic condition that affects bones – Fracture

Hypertensive chronic kidney disease. jhmci.com 85 Nephritic syndrome • A collection of signs (known as a syndrome) associated with disorders affecting the kidneys, more specifically glomerular disorders. • Characterized by having a thin glomerular basement membrane and small pores in the podocytes of the glomerulus, large enough to permit proteins (proteinuria) and red blood cells (hematuria) to pass into the urine. • By contrast, nephrotic syndrome is characterized by only proteins (proteinuria) moving into the urine. Nephritic syndrome, like nephrotic syndrome, may involve hypoalbuminemia due to protein albumin moving from the blood to the urine. jhmci.com 86 N00-N08 Glomerular diseases • Code Also any associated kidney failure (N17-N19). – Type 1 Excludes hypertensive chronic kidney disease (I12.-) • • • • • • • N00 Acute nephritic syndrome N01 Rapidly progressive nephritic syndrome N02 Recurrent and persistent hematuria N03 Chronic nephritic syndrome N04 Nephrotic syndrome N05 Unspecified nephritic syndrome N06 Isolated proteinuria with specified morphological lesion • N07 Hereditary nephropathy, not elsewhere classified • N08 Glomerular disorders in diseases classified elsewhere jhmci.com 87 N00 Acute nephritic syndrome • N00.0 Acute nephritic syndrome with minor glomerular abnormality • N00.1 Acute nephritic syndrome with focal and segmental glomerular lesions • N00.2 Acute nephritic syndrome with diffuse membranous glomerulonephritis • N00.3 Acute nephritic syndrome with diffuse mesangial proliferative glomerulonephritis • N00.4 Acute nephritic syndrome with diffuse endocapillary proliferative glomerulonephritis • N00.5 Acute nephritic syndrome with diffuse mesangiocapillary glomerulonephritis • N00.6 Acute nephritic syndrome with dense deposit disease • N00.7 Acute nephritic syndrome with diffuse crescentic glomerulonephritis • N00.8 Acute nephritic syndrome with other morphologic changes • N00.9 Acute nephritic syndrome with unspecified morphologic changes jhmci.com 4 character constant 88 N08 Glomerular disorders in diseases classified elsewhere • Code First underlying disease, such as: – – – – – – – – – amyloidosis (E85.-) congenital syphilis (A50.5) cryoglobulinemia (D89.1) disseminated intravascular coagulation (D65) gout (M1A.-, M10.-) microscopic polyangiitis (M31.7) multiple myeloma (C90.0-) sepsis (A40.0-A41.9) sickle-cell disease (D57.0-D57.8) jhmci.com 89 Acute kidney failure • Code Also associated underlying condition – N17.0 Acute kidney failure with tubular necrosis – N17.1 Acute kidney failure with acute cortical necrosis – N17.2 Acute kidney failure with medullary necrosis – N17.8 Other acute kidney failure – N17.9 Acute kidney failure, unspecified jhmci.com 90 N18 Chronic kidney disease (CKD) Code First any associated: – diabetic chronic kidney disease (E08.22, E09.22, E10.22, E11.22, E13.22) – hypertensive chronic kidney disease (I12.-, I13.-) – Use Additional code to identify kidney transplant status, if applicable, (Z94.0) • • • • • • • N18.1 Chronic kidney disease, stage 1 N18.2 Chronic kidney disease, stage 2 (mild) N18.3 Chronic kidney disease, stage 3 (moderate) N18.4 Chronic kidney disease, stage 4 (severe) N18.5 Chronic kidney disease, stage 5 N18.6 End stage renal disease N18.9 Chronic kidney disease, unspecified jhmci.com 91 Cystitis Use Additional code to identify infectious agent (B95-B97) • N30.0 Acute cystitis – – – – – – – – – – N30.00 …… without hematuria N30.01 …… with hematuria N30.1 Interstitial cystitis (chronic) N30.10 …… without hematuria N30.11 …… with hematuria N30.2 Other chronic cystitis N30.20 …… without hematuria N30.21 …… with hematuria N30.3 Trigonitis N30.30 …… without hematuria jhmci.com 92 Neuromuscular dysfunction of bladder Use Additional code to identify any associated urinary incontinence (N39.3-N39.4-) • N31 Neuromuscular dysfunction of bladder, not elsewhere classified – N31.0 Uninhibited neuropathic bladder, not elsewhere classified – N31.1 Reflex neuropathic bladder, not elsewhere classified – N31.2 Flaccid neuropathic bladder, not elsewhere classified – N31.8 Other neuromuscular dysfunction of bladder – N31.9 Neuromuscular dysfunction of bladder, unspecified jhmci.com 93 Bladder disorders in diseases classified elsewhere N33 Code First underlying disease, such as: schistosomiasis (B65.0-B65.9) jhmci.com 94 N40 Enlarged prostate • • N40.0 Enlarged prostate without lower urinary tract symptoms N40.1 Enlarged prostate with lower urinary tract symptoms – – – – – – – – – – – • Use Additional code for associated symptoms, when specified: incomplete bladder emptying (R39.14) nocturia (R35.1) straining on urination (R39.16) urinary frequency (R35.0) urinary hesitancy (R39.11) urinary incontinence (N39.4-) urinary obstruction (N13.8) urinary retention (R33.8) urinary urgency (R39.15) weak urinary stream (R39.12) N40.2 Nodular prostate without lower urinary tract symptoms – Additional codes (LUTS) • N40.3 Nodular prostate with lower urinary jhmci.com 95 Questions jhmci.com 96
