The Centers for Disease Control and Prevention (CDC) released the ICD-10 code changes for 2019 on June 11, 2018. The 473 ICD-10 code changes published for the upcoming year are applicable to all hospital inpatient and outpatient coding from October 1, 2018 through September 30, 2019. These include – 279 new ICD-10 codes, 143 revised codes and 51 deleted codes focused primarily around the theme of increased specificity. To ensure accurate claim submissions, it is imperative for healthcare practices and medical billing and coding companies to take note of these coding updates and get familiar on how to use the new codes correctly.

ICD-10 Updates

According to “Elana Oberstein” – MD and Medical Director of Musculoskeletal, “The new 2019 ICD-10 additions helped add more specificity for the classifications of certain conditions”. For instance, if we are taking a condition “muscular dystrophy”, it is possible to detail major forms of the condition like – Myotonic (also called MMD or Steinert’s disease), Duchenne, Becker, Limb-girdle or congenital muscular dystrophy. This level of granularity can help improve the documentation process and thus have a better understanding of specific patient conditions.

FY 2019 ICD-10 includes several code changes for Ophthalmology (Chapter 7: Diseases of the Eye and Adnexa –specifies upper or lower lids) and Gastroenterology (Chapter 11: Diseases of the Digestive System).

Here are some key coding updates of interest to Ophthalmology medical coding service providers, as reported by the American Society of Ophthalmic Administrators –

The 2019 ICD-10 updates include changes to codes for the following eye conditions –

  • Blepharitis
  • Meibomian gland dysfunction
  • Paralytic ectropion
  • Lagophthalmos
  • Rosacea conjunctivitis
  • Brow ptosis
  • Other specified disorders of eye and adnexa

The code changes generally include new specifications for both upper and lower eyelids. Other revisions, simply involve adding a specification for the eye as – right, left or bilateral.

  • K35891 – Other and unspecified acute appendicitis, without perforation, with gangrene

Ischiorectal Abscess

  • K61.31 – Horseshoe abscess

The above mentioned FY 2019 ICD-10 updates for Ophthalmology and Gastroenterology already came into effect on October 1 as there is no grace period provided for implementation.

Managing ophthalmology and gastroenterology medical billing and coding can be made much easier for physicians who partner with an experienced medical billing and coding service provider. Coders in reliable medical coding companies need to be well prepared to help ophthalmologists and gastroenterologists ensure accurate diagnosis reporting with the new code sets.
