CHAPTER 6 CHAPTER-SPECIFIC GUIDELINES (ICD-10-CM CHAPTERS 11-14)
Diseases of Digestive System, Chapter 11 • K00-K95 • Unspecified GI hemorrhage, K92.2 • Combination codes with hemorrhage • Example: K57.21, Diverticulitis of large intestine with perforation and abscess with bleeding
Diseases of the Skin and Subcutaneous Tissue, Chapter 12 • L00-L99 • Also codes to report conditions of the: • Nails • Sweat glands • Hair • Hair follicles
Infections Use additional code before L00 directs coder to report the infection with B95-B97
Pressure Ulcers Stage 1: erythema (redness) of skin Stage 2: partial loss of skin (epidermis or dermis) Stage 3: full thickness loss of skin (up to but not through fascia) Stage 4: full thickness loss (extensive destruction and necrosis)
Diseases of the Musculoskeletal System and Connective Tissue, Chapter 13 • M00-M99 • Most codes specify: • Site: Location on the body • Laterality: Right, left, unilateral, bilateral • Some codes include “multiple sites” such as: • M15.-, Polyosteoarthritis including multiple sites
Infectious Arthropathies • M00-M02 • Direct infections • Invades synovial tissue • Invades the joint • Invasive organism has been identified • Indirect infections • Reactive: Microbial infection identified but not in joint • Postinfective: Microbial antigen present, but not constant and no evidence of multiplication
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
Osteoporosis • M80 and M81 • Systemic condition that affects bones • Fracture sustained with trauma that would not usually cause a fracture • Site is not a component of codes • Category M80, Osteoporosis with current pathological fracture • Age and other osteoporosis codes • Category M81, Osteoporosis without current pathological fracture
