ICD-10-CM Codes Released for Fiscal Year 2019
The ICD-10-CM code set for 2019 includes 279 additions, 51 deletions, and 143 revised codes —for a grand total of 71,932 codes, compared to this year’s 71,701 codes (an additional 228 codes).
Codes Get Even More Specific
Most of the changes, which go into effect October 1, provide more specificity than in existing codes. For example, most of the deleted codes are replaced with multiple new codes to specify not just laterality but location, as well.
Delete: C4311 Malignant melanoma of right eyelid, including canthus
Add: C43111 Malignant melanoma of right upper eyelid, including canthus
Add: C43112 Malignant melanoma of right lower eyelid, including canthus
Delete: C4312 Malignant melanoma of left eyelid, including canthus
Add: C43121 Malignant melanoma of left upper eyelid, including canthus
Add: C43122 Malignant melanoma of left lower eyelid, including canthus
This running theme will render bilateral modifiers unnecessary.
Not all the code changes are to reference laterality. Some deleted are replaced by more specific descriptors.
Delete: K3589 Other acute appendicitis
Add: K35890 Other acute appendicitis without perforation or gangrene
Add: K35891 Other acute appendicitis without perforation, with gangrene
There are a surprising number of new codes in Chapter 7: Diseases of the Eye and Adnexa and Chapter 19: Injury Poisoning, and Certain Other Consequences of External Causes.
