Chapter 6: Nervous System- Pain, Hemiplegia, Chronic Pain Syndromes (G00-G99) Flashcards
(28 cards)
Which codes are used for hemiplegia or hemiparesis?
G81.-
Which codes are used for monoplegia (paralysis of one limb)?
G83.1–G83.3
If side dominance is not documented, how do you assign it?
Ambidextrous → default to dominant
Right side → default to dominant
Left side → default to nondominant
What extra info must be included when coding hemiplegia or monoplegia?
Whether the affected side is dominant or nondominant
What does Category G89 cover?
Pain not elsewhere classified, including:
Acute pain
Chronic pain
Cancer-related pain
Post-op or post-trauma pain
When can you use G89 codes as the primary diagnosis?
Only when the visit is primarily for pain control (e.g., nerve block, injection)
True or False: G89 codes should always be used when pain is present.
False — use them only when they add important info like chronicity or source
When should you use both G89 and a site-specific pain code (e.g., back pain)?
When G89 provides extra info (e.g., chronic pain not captured in the site code)
What’s the sequencing rule if the visit is for pain management?
G89 first, then the site of pain
What if the visit is for another issue and pain is just a symptom?
Site-specific code first, then G89
Should you code post-op pain if it’s routine after surgery?
No
Where do you look for codes about pain from devices or implants?
Chapter 19 (Injury and Complication codes)
What is the default type of post-op pain if not specified?
Acute
What code do you use for acute post-op pain (no complication)?
G89.18
What code do you use for chronic post-op pain (no complication)?
G89.28
If the pain is due to a complication (like painful hardware), how do you code it?
Use a complication code from Chapter 19, and optionally add G89.18 or G89.28 for acute/chronic detail
Is there a set time period that defines chronic pain?
No — it depends on the provider’s documentation
When do you use G89.3?
When pain is caused by primary, secondary, or metastatic cancer
Can G89.3 be coded first?
Yes, if the reason for the visit is pain control
Do you need to list the pain location when using G89.3?
No, it’s optional
What if the visit is to treat the cancer, and pain is present?
Code the cancer first, then G89.3
What is G89.0 used for?
Central pain syndrome (e.g., pain after brain or spinal cord injury)
What is G89.4 used for?
Chronic pain syndrome — only if that exact term is documented
True or False: Chronic pain syndrome (G89.4) is the same as chronic pain (G89.2)
False — they are separate and coded differently
