G47.62

Billable Code Confirmed

ICD-10-CM G47.62 is a valid, billable 5-character ICD-10-CM code for FY2025. The code structure is: G47 (category — Sleep disorders) + .6 (4th character — Sleep related movement disorders) + 2 (5th character — Sleep related leg cramps). No 6th or 7th character is required or available. This code is valid for claims submission from October 1, 2024 through September 30, 2025.

Non-Billable Parent Codes — Never Submit These

❌ G47.6 — 4-character subcategory header — Sleep related movement disorders; not billable

❌ G47 — 3-character category — Sleep disorders; not billable

Always submit G47.62 (all 5 characters) when the provider has confirmed sleep-related leg cramps as a diagnosis. Do NOT substitute the generic symptom code R25.2 1 (Cramp and spasm) when the provider has specifically documented sleep-related or nocturnal leg cramps — G47.62 is the more specific and clinically accurate code.

Critical Distinctions: G47.62 vs. G25.81 (RLS) vs. G47.61 (PLMD) vs. R25.2

Sleep-related leg cramps share the nighttime timing of several other sleep movement disorders, but they are clinically and coding-distinct from each other. Selecting the wrong code is one of the most common errors in sleep medicine coding:

Feature Sleep Leg Cramps G47.62 Restless Legs Syndrome G25.81 Periodic Limb Movement Disorder G47.61 Cramp/Spasm (generic) R25.2 1
Pain ✅ Yes — hallmark feature; intense painful contraction ❌ No — uncomfortable urge/crawling, not pain ❌ No — repetitive jerks, usually no pain Varies
Onset Sudden, during sleep or transition to sleep Worsening symptoms while awake at rest before sleep During sleep — patient often unaware During activity or rest
Duration Seconds to minutes, then resolves Hours until sleep; waxes and wanes Seconds, repetitive every 20-40 sec throughout sleep Variable
Movement Cramping of specific muscle (calf, foot) Urge to move legs to relieve discomfort Stereotyped limb extension/dorsiflexion Any muscle
Relieved by Massage, stretching, walking Movement (temporary); worsens with rest Usually not noticed by patient Varies
Sleep disruption ✅ Yes — awakens patient from sleep ✅ Yes — delays sleep onset Often only via partner observation Variable
Confirmed by Clinical history Clinical criteria (4 IRLSSG criteria) Polysomnography (95810) Symptom description
Excludes2 note G47.6 Excludes2: G25.81 Not mutually exclusive to G47.62 Not mutually exclusive to G47.62 Generic symptom; use specific code when available

Key Rules:

G25.81 (RLS) is Excludes2 at the G47.6 subcategory level — RLS and sleep-related leg cramps CAN be coded together if both are independently documented and diagnosed by the provider

R25.2 1 (cramp and spasm) should NOT be used when the provider has confirmed sleep-related leg cramps — use the specific G47.62 instead; R25.2 1 is for non-sleep-specific cramps

G47.61 (PLMD) and G47.62 can coexist if both are separately diagnosed; they are distinct sleep movement disorders

🔍 Code Description

ICD-10-CM G47.62 classifies sleep-related leg cramps — painful, involuntary contractions of the muscles of the lower extremity (most commonly the calf/gastrocnemius-soleus complex and the intrinsic foot muscles) that occur during sleep or in the transition from wakefulness to sleep. Cramps are sudden in onset, cause intense pain, and typically resolve within seconds to several minutes. The involved muscle is palpably hard and tender during the episode and may remain sore afterward.

Clinical diagnostic criteria for G47.62 (International Classification of Sleep Disorders, ICSD-3):

A painful sensation in the leg or foot associated with a sudden involuntary muscle hardness or tightness
The painful muscle contractions occur during the time in bed — though not necessarily always during sleep
Pain is relieved by forced dorsiflexion of the foot and/or vigorous massage of the affected muscle

Epidemiology and risk factors:

Population	Estimated Prevalence	Key Risk Factors to Code Separately
General adults	~33-50% lifetime prevalence	Idiopathic; age, female sex
Adults >60 years	~70% at least once; ~40% weekly	Age-related muscle changes; polypharmacy
Pregnant women	~30-40% (especially 3rd trimester)	Code pregnancy complication Z codes additionally
Dialysis patients	Up to 75%	N18.6 ESRD; volume/electrolyte shifts
Diabetes patients	Elevated (peripheral neuropathy contribution)	E11.40-E11.49 DM with neuropathy

Common contributing conditions that must be separately coded when documented:

E87.6 — Hypokalemia (diuretic use; code both G47.62 and E87.6)
E83.42 — Hypomagnesemia (code both; magnesium deficiency is a well-documented cause)
E83.51 — Hypocalcemia (electrolyte depletion; separately codeable)
T50.1X5A — Adverse effect of diuretics (thiazides, loops cause electrolyte-related cramps; add T-code when provider documents drug causation)
T46.5X5A — Adverse effect of other antihypertensive drugs (e.g., statins are associated; T-code when provider documents)
I73.9 — Peripheral vascular disease (vascular insufficiency precipitates cramps)
I87.2x — Venous insufficiency (chronic venous stasis; common association)
N18.x — Chronic kidney disease (dialysis-associated cramps are a major subset)
G63 — Polyneuropathy in diseases classified elsewhere (contributing peripheral nerve pathology)

Note

Quinine Is NOT FDA-Approved for Leg Cramps — Compliance Alert: Quinine sulfate was historically the most commonly prescribed drug for nocturnal leg cramps, but the FDA issued a safety communication specifically prohibiting the marketing of quinine for leg cramps (FDA Safety Announcement 2010, reinforced 2012). Quinine is FDA-approved only for uncomplicated malaria. If a provider prescribes quinine for G47.62, the billing of quinine with the G47.62 diagnosis code creates a compliance exposure — quinine claims linked to leg cramp diagnoses are frequently denied by payers and may trigger audits. Document this FDA limitation in the medical record when relevant.

❌ Excludes

Excludes2 at G47.6 Subcategory Level — CAN be Coded WITH G47.62 When Both Are Present

ICD-10 CM G25.81 — Restless legs syndrome (RLS): Specifically listed as Excludes2 at the G47.6 subcategory level — this means RLS and G47.62 are distinct diagnoses that are NOT mutually exclusive. A single patient CAN have both sleep-related leg cramps AND RLS; when both are independently diagnosed and documented by the provider, code both G47.62 and G25.81. However, the diagnoses must be clearly differentiated in the provider’s documentation — do not assume overlap; require explicit dual documentation

Excludes2 at G47 Category Level — CAN be Coded WITH G47.62 When Both Documented

Nightmares (F51.5) — a parasomnia; separately codeable when both present
Nonorganic sleep disorders (F51.-) — insomnia/hypersomnia of psychological origin; separately codeable
Sleep terrors (F51.4) — separately codeable parasomnia
Sleepwalking (F51.3) — separately codeable; some patients have both

Conditions That Require a Different Code — NOT Excludes, Just Different Diagnoses

G25.81 — Restless legs syndrome: When only RLS is present (no actual leg cramps); do NOT substitute G47.62 for RLS
G47.61 — Periodic limb movement disorder: Repetitive limb movements during sleep confirmed by PSG; NOT painful; NOT the same as G47.62; code separately when both independently diagnosed
R25.2 1 — Cramp and spasm (generic): When provider uses this symptom code for non-sleep-specific cramps; when provider confirms sleep-specific cramps, upgrade to G47.62
M79.1 — Myalgia: Daytime muscle pain; not sleep-associated; do NOT use for G47.62
I73.9 — Peripheral vascular disease: PVD causes leg pain/cramps but is coded as the underlying vascular condition; code PVD separately AND G47.62 when both are documented by provider

🛠️ CPT Procedural Crosswalk — wRVU & Assistant Payable Status

ICD-10 CM G47.62 is primarily a primary care, internal medicine, and sleep medicine outpatient diagnosis. Management is largely non-procedural — focused on evaluation, patient education, treatment of underlying causes, and exercise-based interventions. Polysomnography may be ordered when PLMD or other sleep disorders cannot be excluded clinically.

Evaluation & Management

CPT / HCPCS	Description	wRVU (Facility)	Asst. Payable?	Co-Surgeon?
99214	Office visit, moderate complexity — new or established patient with sleep leg cramps requiring evaluation of contributing conditions (electrolytes, medications, vascular history)	1.50	❌ No	❌ No
99213	Office visit, low complexity — routine follow-up, review of treatment response	0.97	❌ No	❌ No
99215	Office visit, high complexity — new patient with multiple contributing conditions (CKD + PVD + polypharmacy cramps) requiring comprehensive assessment and management	2.11	❌ No	❌ No

Sleep Diagnostic Studies

CPT	Description	wRVU	Notes

97530	Therapeutic activities — 15 minutes; functional activity training related to sleep positioning and mobility	0.45	❌ No
J3475	Injection, magnesium sulfate, per 500 mg — when IV magnesium is administered for severe or refractory cramps with documented hypomagnesemia; typically hospital/infusion setting only; link with E83.42 as primary diagnosis	N/A (drug)	N/A
96365	IV infusion, therapeutic; initial hour — administration code when J3475 or other IV treatment is given	0.17	❌ No

⚠️ Quinine Billing Compliance Note: Quinine sulfate (oral) has no FDA-approved indication for leg cramps. The FDA prohibits marketing quinine products specifically for muscle cramps. Billing any quinine drug code (injection or oral) linked to G47.62 creates a significant compliance risk — most payers will deny this combination and it may trigger a fraud/abuse review. If a provider is prescribing quinine for leg cramps, document the off-label rationale thoroughly and verify individual payer policies before claim submission. In general, it is best practice to discuss the FDA guidance with the prescribing provider.

💊 Coding Scenarios

Scenario 1 — Primary Care Evaluation of Nocturnal Leg Cramps

Clinical Vignette: A 68-year-old male presents to his primary care physician for evaluation of nightly calf cramps that awaken him from sleep 3-4 times per week. The cramps involve the right and left calves and resolve with massage and walking. Onset 6 months ago. No daytime urge to move legs. No repetitive leg movements observed by wife. He takes hydrochlorothiazide 25 mg daily for hypertension. Labs drawn. Physician documents “sleep-related leg cramps; likely thiazide diuretic-associated; checking electrolytes.” Stretching program prescribed.

CPT / HCPCS Codes:

99214 — Office visit, moderate complexity (evaluation of new symptomatic complaint with medication review and lab ordering)
80048 — Basic Metabolic Panel (checking for hypokalemia and metabolic contributors)
83735 — Magnesium (evaluating hypomagnesemia as contributing cause)

ICD-10-CM:

G47.62 — Sleep related leg cramps (the confirmed diagnosis)
I10 — Essential (primary) hypertension (the condition for which HCTZ is prescribed; always code the underlying condition)

🏥 Outpatient Coder Tip: G47.62 is the primary diagnosis driving this encounter. If labs return and confirm hypokalemia (E87.6) or hypomagnesemia (E83.42) as a contributing cause at a follow-up visit, add those electrolyte codes. If the provider documents “adverse effect of hydrochlorothiazide causing leg cramps,” add T50.2X5A (Adverse effect of carbonic-anhydrase inhibitors, benzothiadiazides and other diuretics, initial encounter) as an additional code to reflect the drug-causation relationship.

Scenario 2 — Sleep Leg Cramps with Hypomagnesemia, IV Magnesium Administration

Clinical Vignette: A 72-year-old female on long-term furosemide and a proton pump inhibitor (PPI) presents to an infusion center with severe, nearly nightly leg cramps for 3 weeks. Labs reveal serum magnesium of 1.1 mg/dL (low). Her physician documents “sleep-related leg cramps secondary to hypomagnesemia; IV magnesium replacement indicated.” IV magnesium sulfate 2 g in 100 mL NS is administered over 1 hour.

CPT / HCPCS Codes:

96365 — IV infusion, initial hour (magnesium sulfate infusion)
J3475 × 4 — Injection, magnesium sulfate, 4 units × 500 mg = 2,000 mg (2 g) administered
99213 — Office visit (if separately documented and performed on the same day; append -25)

ICD-10-CM:

Primary: E83.42 — Hypomagnesemia (driving the IV infusion order and clinical urgency; the direct cause of cramps)
Secondary: G47.62 — Sleep related leg cramps (the symptomatic manifestation of the hypomagnesemia)
Secondary: T50.1X5A — Adverse effect of loop diuretics (furosemide causing Mg wasting), initial encounter
Secondary: T47.1X5A — Adverse effect of antacids and anti-gastric-secretion drugs (PPI impairs Mg absorption), initial encounter

🏥 Outpatient Infusion Coder Tip: Sequence E83.42 (hypomagnesemia) as primary at the infusion visit — it is the diagnosis directly driving the IV replacement therapy. G47.62 is the symptomatic secondary. Both T-codes (furosemide AND PPI) should be added when the provider documents both as causative — they are NOT mutually exclusive. Always report J3475 in 500 mg units (total dose ÷ 500 mg = units to bill).

Scenario 3 — Differentiating G47.62 from G25.81 (RLS): CDI Scenario

Clinical Vignette: A 58-year-old female presents to a sleep medicine clinic with “leg problems at night — my legs bother me every night and I can’t sleep.” The chart from her PCP has a diagnosis of “restless legs syndrome” coded as G25.81. On interview by the sleep specialist, the patient describes: sudden, painful calf muscle contractions at 2-3 AM that wake her from sleep, resolve with massage in under 5 minutes, and leave the calf sore the next morning. There is no urge to move legs while awake or at rest. The sleep specialist documents “sleep-related leg cramps; NOT restless legs syndrome; patient’s symptoms do not meet IRLSSG criteria.”

CPT / HCPCS Codes:

99245 — Consultation, high complexity (or 99215 in a consultation state) — detailed sleep medicine evaluation with differentiation of two sleep movement disorders
83735 — Magnesium
82607 — Vitamin B12
82728 — Ferritin (relevant as RLS is also now fully excluded; iron deficiency is a RLS trigger, not applicable here but may have been workup)

ICD-10-CM:

G47.62 — Sleep related leg cramps (the corrected, specific diagnosis per sleep specialist)
❌ Remove G25.81 — the sleep specialist has explicitly documented that RLS criteria are NOT met

🏥 CDI Tip: This is a common scenario in sleep medicine — RLS is over-diagnosed and is sometimes assigned when the patient actually has G47.62. The two conditions have fundamentally different clinical features, treatments, and coverage criteria (e.g., dopamine agonist therapy requires G25.81 for authorization; assigning G25.81 incorrectly to a G47.62 patient is both inaccurate coding AND creates downstream prescribing compliance issues). When a specialist explicitly overrides a referring provider’s diagnosis, the specialist’s documented diagnosis governs the code assignment for that encounter.

Scenario 4 — Leg Cramps + PLMD: Dual Sleep Movement Disorder

Clinical Vignette: A 65-year-old male with reported nighttime leg problems undergoes polysomnography (95810). The study demonstrates a periodic limb movement index (PLMI) of 38 (markedly elevated) with associated arousals AND separate recorded episodes of muscle cramping (distinguished by EMG morphology and duration). The sleep physician documents “Periodic limb movement disorder; co-existing sleep-related leg cramps; distinct entities confirmed on PSG.”

CPT / HCPCS Codes:

95810 — Polysomnography, attended, 4+ parameters (the diagnostic PSG)
99214 — Office visit (results interpretation and treatment planning visit)

ICD-10-CM:

G47.61 — Periodic limb movement disorder (PSG-confirmed; code as first sleep diagnosis)
G47.62 — Sleep related leg cramps (co-occurring; separately documented and confirmed by PSG; NOT Excludes to G47.61)

🏥 Coder Tip: G47.61 (PLMD) and G47.62 (leg cramps) are NOT mutually exclusive and CAN be coded together when the provider explicitly documents and distinguishes both diagnoses. These are separate conditions within the G47.6x subcategory — not alternate codes for the same condition. When polysomnography objectively confirms both PLMD and leg cramping episodes, dual coding is both accurate and supported by the diagnostic record.

⚠️ Coding Pitfalls and Tips

	Pitfall or Tip
❌	Do NOT substitute R25.2 1 (cramp and spasm) when G47.62 is documented. R25.2 1 is a non-specific symptom code. Once the provider has confirmed “sleep-related leg cramps” or “nocturnal leg cramps,” G47.62 is the specific, correct code — R25.2 1 is less precise and will not accurately reflect the clinical diagnosis
❌	Do not assume G47.62 = G25.81 (RLS). These are two completely different conditions with different pathophysiology, diagnostic criteria, and treatment. Never code G25.81 based on a description of painful, brief nocturnal cramps — only code RLS when the provider explicitly documents it using IRLSSG criteria
❌	Do not bill quinine for G47.62. Quinine sulfate is FDA-approved only for malaria; its use for leg cramps violates FDA guidance. Billing quinine drug codes linked to G47.62 creates a compliance exposure and will likely result in payer denial or audit
❌	Do not code from labs alone. If a lab shows low magnesium but the provider has not documented either hypomagnesemia or leg cramps as diagnoses, do not assign either E83.42 or G47.62 — the provider must document the clinical correlation
✅	Always separately code underlying contributing conditions. Hypokalemia (E87.6), hypomagnesemia (E83.42), CKD (N18.x), PVD (I73.9), diabetes with neuropathy (E11.40), and drug adverse effects (T50.x) are all separately codeable and may be the primary diagnosis when they are the driving reason for the encounter
✅	Add adverse effect T-codes when drugs are the documented cause. Thiazide diuretics (T50.2X5A), loop diuretics (T50.1X5A), PPIs (T47.1X5A), statins (T46.5X5A), and other medications causally linked to leg cramps per provider documentation should each receive a T-code adverse effect code — this accurately reflects clinical causation and supports medical necessity
✅	Code G47.61 (PLMD) and G47.62 separately when both are confirmed. These are distinct G47.6x conditions that can co-exist; when PSG or clinical evaluation confirms both, code both
✅	G25.81 (RLS) is Excludes2 to G47.6 — code both when both are documented. If the provider documents both RLS AND sleep-related leg cramps as independent diagnoses, code both G25.81 and G47.62 — they are Excludes2, not Excludes1 at the G47.6 subcategory level
