With the delay of International Classification of Diseases, Tenth Revision, Procedural Code Set (ICD-10-PCS) and International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) implementation until October 1, 2015, there was also a delay in updating the codes. It’s been four years since the last annual update, meaning that lots of changes are to be expected. Most of these changes will affect ICD-10-PCS with 3,651 new codes and 487 revised codes, where the majority of changes can be found in the cardiovascular system section. These changes can be found at the Centers for Medicare and Medicaid Services (CMS) website here.
ICD-10-CM will see 1,943 new codes, 313 deletions, and 350 revised codes. The codes and changes are posted on the Centers for Disease Control and Prevention (CDC) National Center for Health Statistics website here.
Added laterality to eye diseases associated with diabetes encompasses most of the additional codes found in code range E08 through E13 in the Endocrine, Nutritional, and Metabolic Diseases section, to give more detail to underlying conditions. For example, E08.321, “Diabetes mellitus due to underlying condition with mild nonproliferative diabetic retinopathy with macular edema” will be deleted and replaced with codes:
Code E78.0, “Pure hypercholesterolemia,” was deleted and replaced with two new codes:
Carpel Tunnel Syndrome
A single code for specific mononeuropathies affecting bilateral limbs in the Diseases of the Nervous System section has also been added to codes in the G56 through G57 code range. Instead of coding G56.01 and G56.02 when a patient is diagnosed with carpel tunnel syndrome in the right and left upper limbs, you will use code G56.03, “Carpal tunnel syndrome, bilateral upper limbs.”
The Diseases of the Eye and Adnexa section will also reflect changes to add laterality. A seventh digit has been added to codes in range H34 through H35 to add even more specificity to retinal disorders. For example, code H34.811, “Central retinal vein occlusion, right eye” will be deleted and replaced with codes:
Laterality codes 1, 2, 3, and 9 representing right, left, bilateral, and unspecified, respectively, have taken the place of the sixth-digit X-placeholder for glaucoma codes in the H40.1 range. Currently, you can report H40.11X1, “Primary open-angle glaucoma, mild stage,” but not the laterality. With the new codes, you will be able to report the laterality by using code H40.1111, “Primary open-angle glaucoma, right eye, mild state,” as well as adding laterality to other codes in this range. Codes in this range with the X-placeholder have been deleted to make way for the more specific codes.
Gastroenteritis and Colitis
Changes to the Diseases of the Digestive System section see the deletion of code K52.2, “Allergic and dietetic gastroenteritis and colitis,” and replaced with codes K52.831 through K52.839 to report specificity for colitis:
Codes K85.0, “Idiopathic acute pancreatitis,” K85.1, “Biliary acute pancreatitis,” and K85.2, “Alcohol induced acute pancreatitis” were deleted and replaced with codes in range K85.00 through K85.92 to accommodate idiopathic, biliary, acute, with and without necrosis or infection, and alcohol or drug induced pancreatitis. Some examples of the new codes are:
Look for new codes in Musculoskeletal System and Connective Tissue section as well. Code range M21.6 will no longer include the X-placeholder in order to report more specific coding options for other acquired deformities of the foot, such as M21.611, “Bunion of right foot” or M21.621, “Bunionette of right foot.”
Hand Joint Pain
Codes M25.541 through M25.549 have been added in order to code joint pain in the hands:
Temporomandibular Joint Disorder
A sixth digit has been added to temporomandibular joint disorder codes in range M26.60 through M26.63 in order to report laterality. For example, you will now be able to specifically report the disorder in the right jaw by reporting code M26.601, “Right temporomandibular joint disorder.”
Cervical Disc Disorders
Sixth digits have also been added to codes in range M50.12 through M50.92 to add the cervical level (e.g., C4-C5) specificity to cervical disc disorders. For example, you will see the deletion of code N50.22, “Other cervical disc displacement, mid-cervical region” that will make room for the more specific codes:
Code range M84.75 has been added to incorporate 59 new codes to use when diagnosing femoral fractures. You will see new codes for atypical type fractures such as:
Ovaries and Fallopian Tube
The Genitourinary System will also see some changes in code selections. Laterality will now be coded with the addition of a fifth-digit requirement for follicular cyst of the ovaries. Codes N83.0 through N83.52 have been deleted and replaced with 29 new codes in code range N83.00 through N83.529. For example, N83.0, “Follicular cyst of ovary” will be deleted and replaced with:
National Institutes of Health Stroke Scale (NIHSS) Scores/Glasgow Coma Scale Scores
The Symptoms, Signs, and Abnormal Clinical and Laboratory Findings section will report new codes R29.700 through R29.742 to report the NIHSS scores and codes R40.2410 through R40.2434 to report Glasgow coma scale scores at specific occurrences.
Laterality has been added to fracture and dislocation codes of the skull and head in code range S02.1 through S03.9. The general codes have been deleted and replaced with 261 more specific codes. For example, code S02.10XA, “Unspecified fracture of base of skull, initial encounter” will be deleted and replaced with:
New sections of codes were added to report 20 new codes for “other” fractures of the foot beginning with code S92.811A, 125 new codes to report fractures of the calcaneus beginning with code S99.001A, 125 new codes to report fractures of the metatarsal beginning with code S99.101A, and 125 new codes to report fractures of the phalanx of the toe beginning with code S99.201A.
