An example of the staggering difference between ICD-9 and ICD-10

We’ve talked plenty about ICD-9 and ICD-10, including the differences and improvements. The best way to truly see how much better and more precise ICD-10 diagnosis codes are than ICD-9 is through some examples.

ICD-9-CM ICD-10-CM
Description Mechanical complication of other vascular device, implant, and graft Mechanical complication of other vascular grafts
Number of codes 1 code (996.1) 49 codes, including:
T82.311A — Breakdown (mechanical) of carotid arterial graft (bypass), initial encounter
T82.312A — Breakdown (mechanical) of femoral arterial graft (bypass), initial encounter
T82.329A — Displacement of unspecified vascular grafts, initial encounter
T82.330A — Leakage of aortic (bifurcation) graft (replacement), initial encounter
T82.331A — Leakage of carotid arterial graft (bypass), initial encounter
T82.332A — Leakage of femoral arterial graft (bypass), initial encounter
T82.524A — Displacement of infusion catheter, initial encounter
T82.525A — Displacement of umbrella device, initial encounter
Description Pressure ulcer Pressure ulcer
Number of codes 9 location codes (707.00 — 707.09); show broad location, but not stage 150 codes that show more specific location and stage, including:
L89.131 — Pressure ulcer of right lower back, stage 1
L89.132 — Pressure ulcer of right lower back, stage 2
L89.133 — Pressure ulcer of right lower back, stage 3
L89.134 — Pressure ulcer of right lower back, stage 4
L89.139 — Pressure ulcer of right lower back, unspecified stage
Page 3L89.141 — Pressure ulcer of left lower back, stage 1
L89.142 — Pressure ulcer of left lower back, stage 2
L89.143 — Pressure ulcer of left lower back, stage 3
L89.144 — Pressure ulcer of left lower back, stage 4
L89.149 — Pressure ulcer of left lower back, unspecified stage
L89.151 — Pressure ulcer of sacral region, stage 1
L89.152 — Pressure ulcer of sacral region, stage 2
Description Angioplasty Angioplasty
Number of codes 1 code (39.50) 854 codes: Specifying body part, approach, and device, including:
047K04Z — Dilation of right femoral artery with drug-eluting intraluminal device, open approach
047K0DZ — Dilation of right femoral artery with intraluminal device, open approach
047K0ZZ — Dilation of right femoral artery, open approach
047K34Z — Dilation of right femoral artery with drug-eluting intraluminal device, percutaneous approach
047K3DZ — Dilation of right femoral artery with intraluminal device, percutaneous approach
047K4ZZ — Dilation of Right Femoral Artery, Percutaneous Endoscopic Approach

ICD-10 offers a lot more codes and much more specificity, right? That’ll certainly help documentation accuracy.
