2019 ICD-10:

Dive Into This New Round of 2019 ICD-10-CM Additions and Revisions

Get the hang of all the new ICD-10-CM changes now, just in time for October.

ICD-10-CM has a broad range of sweeping changes affecting neoplasms of the eyelid and surrounding structures. The updated ICD-10-CM index and tabular will break down the following C and D codes to further specify melanomas, carcinomas, and other malignant and benign neoplasms of the right upper, right lower, left upper, and left lower eyelid.

Additionally, radiology coders should prepare for a new set of urethral stricture codes, hemifacial spasm, and muscular dystrophy codes.

Keep reading for further instructional detail on these important additions and revisions to the radiology diagnostic code set.

I.D. Important Revisions to Malignant, Benign Neoplasm of Eyelid Codes

Any revisions to malignant neoplasm diagnoses are sure to affect those working within the radiology specialty. This year, the focus turns to malignant and benign neoplasms of the eyelid and surrounding parts. Consider these various code revisions to add to your repertoire come October 1:

  • C43.11-— Malignant melanoma of right eyelid, including canthus
  • C4A.11- — Merkel cell carcinoma of right eyelid, including canthus
  • C44.10- — Unspecified malignant neoplasm of skin of eyelid, including canthus
  • C44.11- — Basal cell carcinoma of skin of eyelid, including canthus
  • C44.12- — Squamous cell carcinoma of skin of eyelid, including canthus
  • C44.19-— Other specified malignant neoplasm of skin of eyelid, including canthus
  • D03.1- — Melanoma in situ of eyelid, including canthus
  • D04.1- — Carcinoma in situ of skin of eyelid, including canthus
  • D22.1- — Melanocytic nevi of eyelid, including canthus
  • D23.1- — Other benign neoplasm of skin of eyelid, including canthus.

Additionally, ICD-10-CM will incorporate a brand-new code to report sebaceous cell carcinomas of the right upper, right lower, left upper, and left lower eyelids:

  • C44.13- — Sebaceous cell carcinoma of skin of eyelid, including canthus

Get Ready for These New Urethral Stricture Codes

Next up, you will want to familiarize yourself with these new additions and revisions to the urethral stricture diagnosis codes:

  • N35.816 —  Other urethral stricture, male, overlapping sites
  • N35.819 — … unspecified site
  • N35.82 — Other urethral stricture, female
  • N35.919 — Urethral stricture, unspecified, male
  • N35.911 — Unspecified urethral stricture, male, meatal
  • N35.912 — Unspecified bulbous urethral stricture, male
  • N35.913 — Unspecified membranous urethral stricture, male
  • N35.914 — Unspecified anterior urethral stricture, male
  • N35.916 — Unspecified urethral stricture, male, overlapping sites
  • N35.919 — … unspecified site
  • N35.92 — … female
  • N99.116 — Postprocedural urethral stricture, male, overlapping sites.

As you can see, ICD-10-CM ups the ante on urethral stricture coding by incorporating modifying terms such as bulbous, membranous, and anterior to distinguish between varying forms. “This means that, when analyzing dictation reports of the urinary tract, you’ve got to be extra diligent in looking out for these keywords,” advises Barry Rosenberg, MD, chief of radiology at United Memorial Medical Center in Batavia, New York. “You may not find them in the impression, however, so be sure to refer back to the findings in case the provider further clarifies the diagnosis in the body of the report,” Rosenberg says.

Keep an Eye Out for These Brand-New E, G Codes

Last, but not least, make way for a few new miscellaneous codes impacting your lipoprotein, hemifacial spasm, and muscular dystrophy diagnosis coding. In October, you’ll see ICD-10-CM introduce new codes to report elevated lipoprotein(a) levels in addition to other types of hyperlipidemia:

  • E78.41 — Elevated Lipoprotein(a)
  • E78.49 — Other hyperlipidemia.

Also, you’ll have the option of reporting clonic hemifacial spasms with left, right, bilateral, or unspecified designations:

  • G51.31 — Clonic hemifacial spasm, right
  • G51.32 — Clonic hemifacial spasm, left
  • G51.33 — Clonic hemifacial spasm, bilateral
  • G51.39 — Clonic hemifacial spasm, unspecified.

Finally, instead of reporting muscular dystrophy exclusively under code G71.0 (Muscular dystrophy), you’ll have these four new options to choose from:

  • G71.00 — Muscular dystrophy, unspecified
  • G71.01 — Duchenne or Becker muscular dystrophy
  • G71.02 — Facioscapulohumeral muscular dystrophy
  • G71.09 — Other specified muscular dystrophies.
