Neurology & Pain Management Coding Alert

ICD-10 2023:

Substance Use, Poisoning Code Dx Groups Swell

Another well-represented group in 2023 is 2-wheeled vehicle accident diagnoses.

Coders should look at the new list of codes for patients that report with a consumption or poisoning issue related to substance use.

Why? ICD-10 2023 has new codes aimed at making your claims for patients with various substance use issues more detailed. The new specificity should help coders “paint a picture” of the patient’s issues using ICD-10 codes. This should, in turn, lead to better patient outcomes and more directed care.

Take a look at these new ICD-10 codes, set to take effect Oct. 1, 2022.

ICD-10 Changes Several Substance Categories

When ICD-10 2023 takes effect, there will be new (but similar) additions to each of these current code sets:

  • F10.9- (Alcohol use, unspecified)
  • F11.9- (Opioid use, unspecified)
  • F12.9- (Cannabis use, unspecified)
  • F13.9- (Sedative, hypnotic or anxiolytic-related use, unspecified)
  • F14.9- (Cocaine use, unspecified)
  • F15.9- (Other stimulant use, unspecified)
  • F16.9- (Hallucinogen use, unspecified)
  • F18.9- (Inhalant use, unspecified)
  • F19.9- (Other psychoactive substance use, unspecified)

New codes: In ICD-10 2023, coders can add these codes to the above diagnosis sets:

  • F10.90 (Alcohol use, unspecified, uncomplicated)
  • F10.91 (Alcohol use, unspecified, in remission)
  • F11.91 (Opioid use, unspecified, in remission)
  • F12.91 (Cannabis use, unspecified, in remission)
  • F13.91 (Sedative, hypnotic or anxiolytic use, unspecified, in remission)
  • F14.91 (Cocaine use, unspecified, in remission)
  • F15.91 (Other stimulant use, unspecified, in remission)
  • F16.91 (Hallucinogen use, unspecified, in remission)
  • F18.91 (Inhalant use, unspecified, in remission)
  • F19.91 (Other psychoactive substance use, unspecified, in remission)

Methamphetamine Poisoning Codes Get More Specific

The ICD-10 code set T43.6- (Poisoning by, adverse effect of and underdosing of psychostimulants) will devote a new section solely to methamphetamine use. The new codes you’ll have for this condition in ICD-10 2023 are:

  • T43.65 (Poisoning by, adverse effect of and underdosing of methamphetamines)
  • T43.651 (Poisoning by methamphetamines accidental (unintentional))
  • T43.651A (Poisoning by methamphetamines accidental (unintentional), initial encounter)
  • T43.652 (Poisoning by methamphetamines intentional self-harm)
  • T43.652A (Poisoning by methamphetamines intentional self-harm, initial encounter)
  • T43.653 (Poisoning by methamphetamines, assault)
  • T43.653A (Poisoning by methamphetamines, assault, initial encounter)
  • T43.654 (Poisoning by methamphetamines, undetermined)
  • T43.654A (Poisoning by methamphetamines, undetermined, initial encounter)
  • T43.655 (Adverse effect of methamphetamines)
  • T43.655A (Adverse effect of methamphetamines, initial encounter)
  • T43.656 (Underdosing of methamphetamines)
  • T43.656A (Underdosing of methamphetamines, initial encounter)

Impact: This will make coding for these methamphetamine use conditions more specific. Previously, you would have had to code these conditions with T43.691- (Poisoning by other psychostimulants, accidental (unintentional)) through T43.696- (Underdosing of other psychostimulants).

Pay Attention to This Bulked-Up V Code Group

There are also a staggering number of new V codes in the External Causes of Morbidity (V00-Y99) code set.

There are far too many codes to list, but they mostly concern some type of accident on a two-wheeled motorized vehicle that is not a motorized scooter (e.g., motorcycle, electric bike). The new codes, which will number in the hundreds, will be bookended by V20.01 (Electric (assisted) bicycle driver injured in collision with pedestrian or animal in nontraffic accident) and V29.9XXA (Rider (driver) (passenger) of other motorcycle injured in unspecified traffic accident, initial encounter).

No scooter codes: Of note, of the dozens of new codes in this family, none describe injuries from electric or motorized scooters. Widespread use of these scooters has dramatically increased injuries, especially as many tourists use them for the first time when traveling.

Do this: Resist the temptation of using these new codes that specify bicycle or motorcycle in the descriptor for scooter-related injuries. Contact your payer if you need more information on how to report V codes for motorized scooter accident victims.

Other diagnoses in the V code additions for 2023 include:

  • V22.01 (Electric (assisted) bicycle driver injured in collision with two- or three-wheeled motor vehicle in nontraffic accident)
  • V24.19 (Other motorcycle passenger injured in collision with heavy transport vehicle or bus in nontraffic accident)
  • V27.01 (Electric (assisted) bicycle driver injured in collision with fixed or stationary object in nontraffic accident)
  • V28.99 (Unspecified rider of other motorcycle injured in noncollision transport accident in traffic accident)
  • V29.31 (Electric (assisted) bicycle (driver) (passenger) injured in unspecified nontraffic accident).
