Ten Unusually Specific ICD-10 Codes

  • Y93.D1: Activity, knitting and crocheting

    Y93.D1: Activity, knitting and crocheting

    Knitting is back, and it's popular with more than just your grandmother — even teenagers are picking up needles. If your patient lacks the fine motor skills or functionality required for this hobby, or is a particularly enthusiastic knitter, you may find yourself using this code.

  • T75.81: Effects of abnormal gravitation [G] forces

    T75.81: Effects of abnormal gravitation [G] forces

    Spend any time in space lately? Astronauts experiencing prolonged periods in zero gravity often return home with issues related to osteoporosis.<sup>2</sup> NASA's on the case, but until they find a solution, use this code when treating the next Neil Armstrong.

  • V10.0: Pedal cycle rider injured in collision with pedestrian or animal in nontraffic accident

    V10.0: Pedal cycle rider injured in collision with pedestrian or animal in nontraffic accident

    All physical activity comes with risk, bicycling included. Although physical activity can have a protective effect on rheumatoid arthritis,<sup>3</sup> remind your patients to make way for ducklings when out for a ride, or else they might find themselves in the middle of a pedestrian or animal nontraffic accident.

  • W27.4: Contact with kitchen utensil

    W27.4: Contact with kitchen utensil

    Is your patient the next Chopped champion? Maybe not, if pain is affecting their ability to perform activities of daily living. A 2016 population-based cross-sectional study<sup>4</sup> of people aged 65 years and older found that participants with musculoskeletal conditions were "significantly more often affected" by these issues than those without diseases such as osteoporosis or osteoarthritis.

  • Y93.E2: Activity, laundry

    Y93.E2: Activity, laundry

    As in the previous slide, some patients may struggle with basic housekeeping activities such as laundry, vacuuming (Y93.E3), and floor mopping (Y93.E5). Turns out chores are indeed a hazard to your health.

  • W56.02XD: Struck by dolphin, subsequent encounter

    W56.02XD: Struck by dolphin, subsequent encounter

    Studies published in the <i>Journal of Rheumatology,</i><sup>5</sup> the <i>American Journal of Cardiology,</i><sup>6</sup> and the <i>European Journal of Physical and Rehabilitation Medicine</i><sup>7</sup> all indicate that water-based exercise can positively affect osteoarthritis, vascular function, and ankylosing spondylitis, among other conditions — but marine mammals can certainly be hazardous to your health. Be sure to counsel patients on the dangers of striking dolphins, or they'll be back in your office sooner than you think.

  • Y93.C1: Activity, computer keyboarding

    Y93.C1: Activity, computer keyboarding

    Keeping in touch with friends and family is important, but sometimes we need to step away from social media. Prolonged typing or texting can aggravate already-swollen joints in the hands and fingers, leading to flare-ups or pain. In 2014, the <i>Journal of Orthopedic Case Reports</i> published a study<sup>8</sup> of the effect of cell phone use (and abuse) on patients' hand and finger joints.

  • Z63.1: Problems in relationship with in-laws

    Z63.1: Problems in relationship with in-laws

    The psychosocial effects of pain and arthritis are no laughing matter, much like in-law relationships. If your patients are struggling with familial relationships, consider screening them for depression and anxiety, both of which are comorbidities to rheumatic diseases.<sup>9</sup>

  • Y92.253: Opera house as the place of occurrence of the external cause

    Y92.253: Opera house as the place of occurrence of the external cause

    The social impact of arthritic diseases can take a toll on your patients.10 But once their symptoms are under control,<sup>11</sup> encourage them to get out and enjoy some extracurricular activities. For example, opera is a low-impact cultural activity, but remember: patients should beware of phantoms.

  • V97.33XD: Sucked into a jet engine, subsequent encounter

    V97.33XD: Sucked into a jet engine, subsequent encounter

    Safety first, folks.
